Hello,

After the rev. 15229 (IDE: designer: implemented loading lists of ancestors) from Mattias, something got wrong with the parsing of one of my forms. I cannot create a sample project, don't know what is happening. Everytime I open such unit, the .lfm file is opened instead of an instance of the form. If I close the page that present the .lfm, move to the .pas and press F12, the .lfm file is opened again, and no form. Rev 15228 is ok. Tips?

Thanks.

Probably some sub function returned an error code without notifying the user about the error.
Start lazarus in a console with
--debug-log=log.txt
and send the log.txt to me.

The relevant line is:
[TJITComponentList.AddJITChildComponentFromStream] ERROR reading form stream of Class 'TOrcamentoEditForm' Error: Error reading FaturasStringGrid.ColWidths: Access violation

and the object is:
object FaturasStringGrid: TStringGrid
Left = 8
Height = 81
Width = 209
ColCount = 5
DefaultColWidth = 32
DefaultRowHeight = 16
FixedColor = clBtnFace
Options = [goFixedVertLine, goFixedHorzLine, goVertLine, goHorzLine, goRangeSelect, goSmoothScroll]
RowCount = 4
TabOrder = 0
ColWidths = (
32
32
27
32
32
)

       end

If I remove the ColWidths property from the .lfm, the form is streamed flawlessly.

Now it's a bit easier.

Fixed in 15264, in my opinion Filer.Ancestor should have ancestor of component being streamed, instead it has ancestor's form, I made sure ancestor is a compatible grid.

Now I could resolve 11363 if I had access to the bug tracker, can somebody please do that for me?.

Perfect, here it works flawlessly with my projects. Thanks Jesus and a special thanks to Mattias.

Now back to PressObjects.

If being available (during read) means that Filer.Ancesor is not nil, then I think there is a problem, I did some debugging and found that is currently the case. In fact that's why it failed.

I said "instead it has ancestor's form" my foult I wanted to say "instead it has component's form".

Arrgh. This was experimental code. I removed it.
