From 975452f5d5c36e43e84df52835bbdf1f687ac494 Mon Sep 17 00:00:00 2001 From: stagknee <241821830+stagknee@users.noreply.github.com> Date: Thu, 22 Oct 2026 03:02:35 -0500 Subject: [PATCH 1/8] fix(widgets): read an object property's sub-properties declared without a propertyGroup (mendixlabs/mxcli#1632) Every Marketplace Calendar written by mxcli failed a plain `mx check` with CE0463 "The definition of this widget has changed". The Calendar has no embedded template, so its Type is generated from the .mpk, and its toolbarItems object list declares its sub-properties directly under , each with a element. modelsdk/widgets/mpk read only , so toolbarItems had no Children and was stored with ValueType.ObjectType null. The parser now reads both shapes, as sdk/widgets/mpk already does; a direct sub-property takes its category from its own . On an 11.12.5 app the stored Calendar equals a copy rewritten by `mx update-widgets` (ids stripped), and the object-list widgets of doctype-tests/32 are stored byte-identical to before.

The same writer serves an object-list item's template (an Accordion group's `headerText`) and a Data grid 2 column's dynamic text, and all three failed; on Mendix 11.12.4 they now build with 0 errors. `describe page` printed such a parameter as the bare attribute (`{1} = Label`), which re-executed into CE1613 "The selected attribute 'M.Parent.Label' no longer exists"; it now prints `M.Parent_Child/Label`. The companion report, an expression parameter (`{1} = if 1 = 1 then 'A' else 'B'`) stored as an attribute name (mendixlabs/mxcli#1495), was fixed in v0.25.0 (#823) and is now pinned by a test. - **`alter entity … add event handler` adds a second handler for the same event** (mendixlabs/mxcli#1540) — `add event handler on before commit call M.Second($currentObject)` failed with "event handler already exists for Before Commit" when the entity already had one, though Studio Pro allows several handlers for one event and `create or modify entity` with two `on before commit` clauses stores both (measured on 11.12.4: two Before Commit handlers are 0 errors, a void-returning one is CE7247, so the check does look at them). A handler is now identified by its moment, event and microflow: another microflow adds a second handler, the same microflow again is still a duplicate. The same key had made `add event handler if not exists … call M.New` skip — reporting "already exists" — whenever any handler for the event existed, and `drop event handler on before commit` remove whichever handler was stored first. `drop event handler` now takes `call M.Mf` to say which one; without it, a drop that matches several handlers is refused and names them. +- **A Marketplace Calendar written by mxcli passes a plain `mx check`** (mendixlabs/mxcli#1632) — every Calendar failed with CE0463 "The definition of this widget has changed" until `mxcli fix widgets` or Studio Pro's "Update all widgets"; `mxcli docker check` hid it, since it runs that update on a temporary copy first.

Measured on Menditect's MtaPluginModule 11.5.5 (Marketplace 214717) into an 11.15 MPR v2 app: 32 units, `mx check` 0 errors, module listed as *Protected AddOn*, and the plugin starts and serves its endpoint. - **`test --attach` on Mendix 11.14.0 says why it is refused instead of blaming an entity** — that version's `mxbuild --serve` fails every build after its first, so since ako/mxcli#1917 the attach builds on a fresh serve process, whose first build asks for a runtime restart whatever changed. The refusal claimed "an entity or association changed" and suggested restarting the dev loop, which does not help; it now says the build could not be done incrementally and points to `--local`. The hosting app's pages survive either way. 11.15.0 builds incrementally and attaches as before. - **`describe microflow` no longer leaves out a note linked to the start event or to another note** (ako/mxcli#1933, mendixlabs/mxcli#1731) — such a note counted as linked, so it was not printed as a free note, and the element it is linked to prints no `@annotation`, so it was not printed at all; re-executing the description deleted it. It is now described as a free note, after a `-- WARNING` line saying the link itself has no MDL form and a rewrite drops it. - **Rebuilding a described decision no longer adds a merge** (ako/mxcli#1929, mendixlabs/mxcli#1727) — a `case`, `split type` or `if … elsif` one of whose branches returns is described with its own merge as a label (`end case; join shared1; merge shared1;`). Executing that as a fresh create built the decision's merge and a second one for the label, wired merge to merge, and every further describe → drop + create added another (`join junctionN; merge junctionN;`).

The reference project is also read for the package's Java and JavaScript sources (DESCRIBE JAVA/JAVASCRIPT ACTION), so marketplace diff and update would report every action of such a module as changed locally (mendixlabs/mxcli#1441). Write the package's declared files beside it, as mx module-import does. The units are not converted to the project's Mendix version, so refuse a tree saved with a newer Mendix than the project. Split units only out of modules and folders, read the package entry and module name once, and keep the refcache comment true for a reference that stays MPR v2.

It is now printed as stored, `if X then else end if;`, which builds Studio Pro's shape.

The package's declared files (`javasource/`, `javascriptsource/`, …) are written beside the reference project as `mx module-import` would, so `marketplace diff` and `update` do not report every Java or JavaScript action as changed; the units are not converted to the project's Mendix version, so a package saved with a newer Mendix than the project is refused. - **`test --attach` on Mendix 11.14.0 says why it is refused instead of blaming an entity** — that version's `mxbuild --serve` fails every build after its first, so since ako/mxcli#1917 the attach builds on a fresh serve process, whose first build asks for a runtime restart whatever changed. The refusal claimed "an entity or association changed" and suggested restarting the dev loop, which does not help; it now says the build could not be done incrementally and points to `--local`. The hosting app's pages survive either way. 11.15.0 builds incrementally and attaches as before. - **`describe microflow` no longer leaves out a note linked to the start event or to another note** (ako/mxcli#1933, mendixlabs/mxcli#1731) — such a note counted as linked, so it was not printed as a free note, and the element it is linked to prints no `@annotation`, so it was not printed at all; re-executing the description deleted it. It is now described as a free note, after a `-- WARNING` line saying the link itself has no MDL form and a rewrite drops it. - **Rebuilding a described decision no longer adds a merge** (ako/mxcli#1929, mendixlabs/mxcli#1727) — a `case`, `split type` or `if … elsif` one of whose branches returns is described with its own merge as a label (`end case; join shared1; merge shared1;`). Executing that as a fresh create built the decision's merge and a second one for the label, wired merge to merge, and every further describe → drop + create added another (`join junctionN; merge junctionN;`). The label's merge is now the decision's merge when nothing else reaches it, so the round trip keeps one merge. diff --git a/cmd/mxcli/marketplace/moduletree.go b/cmd/mxcli/marketplace/moduletree.go index b38a3f4b79..e59339e96e 100644 --- a/cmd/mxcli/marketplace/moduletree.go +++ b/cmd/mxcli/marketplace/moduletree.go @@ -7,6 +7,8 @@ import ( "bytes" "fmt" "io" + "path/filepath" + "strings" modelsdk "github.com/mendixlabs/mxcli" "github.com/mendixlabs/mxcli/internal/zipentry" @@ -28,6 +30,22 @@ import ( // transplant uses.

A unit already synced by an earlier version keeps its doubles; re-create the page to repair it. - **`alter workflow` no longer guesses which outcome to drop** (ako/mxcli#808) — `drop X outcome 'V'` with two outcomes of value `V` dropped the first; it is refused as ambiguous now. `check --references` also resolves an activity reference by name before caption, as `exec` does, so its guards no longer go silent on a target captioned like another activity's name. - **describe → exec keeps a decision whose true branch is empty** (ako/mxcli#1963, mendixlabs/mxcli#1742) — `describe microflow` folded such a decision into `if not(X) then end if;`, and executing that stored `not(X)` with the true and false outcomes swapped: the same behaviour, a different model in Studio Pro. It is now printed as stored, `if X then else end if;`, which builds Studio Pro's shape.

The reference project is now built by splitting that tree into units and writing them with the same raw-unit writer the transplant uses; protection settings travel unchanged. Measured on Menditect's MtaPluginModule 11.5.5 (Marketplace 214717) into an 11.15 MPR v2 app: 32 units, `mx check` 0 errors, module listed as *Protected AddOn*, and the plugin starts and serves its endpoint. The package's declared files (`javasource/`, `javascriptsource/`, …) are written beside the reference project as `mx module-import` would, so `marketplace diff` and `update` do not report every Java or JavaScript action as changed; the units are not converted to the project's Mendix version, so a package saved with a newer Mendix than the project is refused. diff --git a/mdl-examples/bug-tests/1976-widget-sync-keeps-integer-widths.mdl b/mdl-examples/bug-tests/1976-widget-sync-keeps-integer-widths.mdl new file mode 100644 index 0000000000..c316aca47f --- /dev/null +++ b/mdl-examples/bug-tests/1976-widget-sync-keeps-integer-widths.mdl @@ -0,0 +1,41 @@ +mdl 1; +-- ============================================================================ +-- Regression: ako/mxcli#1976 (mendixlabs/mxcli#1748) - widget sync wrote +-- every integer inside a changed widget as a BSON double +-- ============================================================================ +-- +-- Symptom (before fix): +-- When `mxcli widget sync` changed a pluggable widget, every int32/int64 in +-- its Type and Object came back as a double, including a text box held in +-- the widget's slot.

The difference is upstream tickets the fork already closed as fixed: mirror.py leaves closed mirrors alone, and the triage session cannot read upstream, so nothing listed which upstream tickets are waiting to be closed. mirror.py, which can read upstream from GitHub Actions, now labels a mirror `upstream-open` while it is closed here as completed and its upstream original is still open, and removes the label when upstream closes it or the mirror is reopened. It confirms an upstream closure with a direct lookup before removing the label, so a short upstream listing cannot strip them all. The run summary lists the upstream numbers as `fixed_here_open_upstream`, and the triage board lists the labelled mirrors. test_mirror.py adds seven scenarios (H-N); the script on main fails all seven and passes the existing seven.

The Calendar's `toolbarItems` object list declares its sub-properties directly under ``, not inside a ``, and the `.mpk` parser behind generated widget templates read only the grouped shape, so the list was stored with no definition of its items. Both shapes are now read, a direct sub-property takes its category from its own `` element, and the stored Calendar equals what `mx update-widgets` writes.
