[BjBe82]

Checklist before submitting a bug report

• I have reviewed CONTRIBUTING.md document
• I have done a quick search on the issue tracker to check if the bug report is not redundant

Context

Based on the "Kernel Modeling Language Version 1.0 Beta 2.6" chapter "7.4.9.4 Base Expressions" the instantiation of classes should be possible. But the example provided there shows errors in the SysIDE.

Note: Syntax has changed and now uses the "new" keyword: ... new Member(...) based on spec "Kernel Modeling Language Version 1.0 Beta 3"

Steps to reproduce the bug

Add the following to the editor:

private import ScalarValues::*;

class Member {
    feature firstName : String;
    feature lastName : String;
    feature memberNumber : Integer;
    feature sponsor : Member [0..1];
}
feature thisMember = Member("Jane", "Doe", 1234, null);
feature nextMember = Member(
    firstName = "John",
    lastName = "Doe",
    sponsor = thisMember,
    memberNumber = thisMember.memberNumber + 1
);

Current result

Error reported:

Expected result

No errors.

Hi, this repository (and the sensmetry.sysml-2ls extension with the name SysIDE Editor Legacy) is no longer being maintained and will be archived soon.

We strongly recommend switching to the new Syside Editor (ID sensmetry.syside-editor) extension (VSCode Marketplace, Open-VSX), which supports the newest SysML v2 spec and this issue fixed, while also being significantly more performant.

For more information about the switch, read our announcement.
