Assembly: BOM generation failures (v1.0)

[wooddragon48]

Is there an existing issue for this?

• [X] I have searched the existing issues

Problem description

The Create Bill of Materials tool for the Assembly workbench only creates an empty spreadsheet regardless of the parts in the assembly. After saving, closing, and reopening the file the spreadsheet has a single column labeled "Index". See attached images for the before and after saving view of the spreadsheet.

I have attached a exceedingly simple file that exhibits the problem.

Can confirm:

@PaddleStroke @adrianinsaval @chennes this is the same error as the issue which was never found

It does create the BOM spreadsheet. But I have to add the columns to the BOM twice and add a custom column in order for it actually populate the SS.

I can reproduce the error in V1.0. But not in the version listed below. Some mysterious commit must have fixed it?

Sounds like a regression of https://github.com/FreeCAD/FreeCAD/pull/16671 If the error is not in main then perhaps it's a backport issue. Though I don't remember fixing regression on the BOM tool, only on the exploded view tool (https://github.com/FreeCAD/FreeCAD/pull/17724)

Now it s reproduce for Mac M1 2020.

[H-Tsubota]

I have same problem and did some research.

This issue is same as #18615 and the problem (i.e. lack of "doCommandEval") is fixed with commit "d1707fdf10e0468155bf57ace64e219e2ab17b7e" at 2024/12/20.

Maybe we can close this issue.
