unknown component issues with v21 (1121)
lazarus / 8-Other

I am getting unpublished property errors with TDateEdit (Text) and
others (TCalcEdit). I was forced to switch to v21 from v18. My first
opportunity to check existing code produced load failures.

This is a fragment of the LFM

          object DTEDeparture: TDateEdit
            Left = 640
            Height = 23
            Top = 71
            Width = 80

            TabOrder = 4
            Text = '15-8-06'
            ButtonWidth = 23

Text and ParentColor both error as unpublished. Were there changes to
the Misc tab components?

Thanks

So what is the error ?
You get this when you switch from .18 to .21  or do you get this when
swithcing back from .21 to .18 ?

In bothacases, removing the offending properties from the lfm will
solve it

I asked on the mailing list what the reasons were. I haven't had a
reply yet.

Its a very long list of errors. (The clipboard isnt available at that
point) My impression was that it could be something else - as removing
the properties it claimed were now unpublished makes no sense.

It basically says that (I use these two examples, this also happens
with calcedit). Text and ParentColor are unpublished properties of
dateedit. (At this point the line of code in my program that
references Text is selected).

 I havent allowed automatic removal as it just hasnt seemed correct
that Text would be unpublished. I did a test with a new application
with dateedit and text was available via code completion. This
application was started some time ago with v16 and has been moved
forward.

I suspect it is something else. These 'misc' components have always
been problematic. They are also the most likely to fail with GTK2 for
example. (The edits with buttons. If you place them on a panel or 'tab
page etc' they lose their glyph. I havent tried that in several
versions. That might be fixed. But they have been breakable - and
useful  )
