Empty widget property list `()` is a parse error in CREATE PAGE — for every widget form, not just pluggable

[MohamedGamalEzzatAli]

mxcli version: v0.20.0 (release 2026-08-28) · parse-level, no project needed

A widget with an empty property list fails to parse; omitting the parens entirely works. Bites anyone generating MDL from a template where the property list can be empty (the natural emitter output is name (…props…) with zero props).

Repro

CREATE PAGE MyModule.ProbePage (Layout: Atlas_Core.Atlas_Default) {
  PLUGGABLEWIDGET 'com.mendix.widget.web.fileuploader.FileUploader' fileUploader1 ()
};

Syntax errors found:
  - line 2:83 mismatched input ')' expecting the start of a statement (create, alter, drop, show, describe, …)

Same for built-in widgets — CONTAINER c1 ():

  - line 2:16 mismatched input ')' expecting the start of a statement (create, alter, drop, show, describe, …)

Control: PLUGGABLEWIDGET '<key>' fileUploader1 (no parens) and CONTAINER c1 { } both parse and exec fine.

Expected

() accepted as an empty property list (SQL-ish grammars generally allow it), or a targeted error message ("empty property list — omit the parentheses") instead of the generic mismatched-input cascade.
