[Lazarus] ListView.OnSelectItem - which LCL backend is correct?
Hi, I found a bug in LCL's TListView. The OnSelectItem event. When you select an item in the Listview, that event is triggered twice. Once with the Selected = True (indicating the new selection) and once with the Selected = False (indicating the old selection). But the order of those events are reversed between LCL-Win32/64 and LCL-GTK2. I haven't tried other LCL backends, so don't know the order of them. So which backend has the correct behaviour, so I can file a bug report for the other one. Seeing has LCL by design is very Windows centric, I'm assuming the LCL-Win32/64 is the correct behaviour? Unfortunately the documentation doesn't specify the expected behaviour. http://lazarus-ccr.sourceforge.net/docs/lcl/comctrls/tcustomlistview.onselectitem.html Also, it seems that under LCL-GTK2 the first time you select a new item, it generates this event more times than under LCL-Win32/64.

from forum:
you can set the webclient.logfile to some valid filename and examine the resulting

Following the response for:

that is the same (except for 1st line where response begins with

maybe missing headers?

Looks like it, a header 'Content-type: application/javascript' should be added.
Look in googleservice.pp, line 522
Req.SetContentFromString(AInput);
There add a
if (AMethod'GET') then
Req.Headers.Add('Content-Type: application/json');
Strange.
I have created a calendar sync app which does both POST and PATCH.
Probably I have forgotten to copy some changes to the FPC repo.
Please test and report, if this helps, I'll update the API.
(I need to do some other changes anyway)

Re: [Lazarus] IDE unable to load form due to missing property
It probably should - but I see this error all the time when modifying components and you do need to do something more than just ignore the error. Maybe a bug report is needed. Another thought - at run time an unknown property error might be better reported as a warning rather than as an error.
