Hi all,

there seems to be no activeFocusControlId when a view has been detached.
The <activeWhen> expression for my handler looks like

<activeWhen>
<and>
<with variable="activeFocusControlId">
<equals value="graphicalViewer">
</equals>
</with>
<with variable="selection">
<count value="1">
</count>
<iterate>
<adapt type="MyType">
</adapt>
</iterate>
</with>
</and>
</activeWhen>

If the view is attached it works like expected.

This might be related to

https://bugs.eclipse.org/bugs/show_bug.cgi?id=212292

TIA,
Marco

One way to test that would be to pick up a version of 3.4 M5 and see if
you still have the problem, or simply remove your 'with
variable="selection"' clause and see if your handler becomes active when
the focus control is active.

Thanks for your quick answer.

We are developing against a target platform, which is something between
3.3.0 and 3.3.1.
I debugged the WithExpression and the activeFocusControlId was null. I
will try to setup a target platform with 3.4M5, but this may take
awhile. Are there any plans to fix the bug mentioned above and this one
in 3.3.2?

TIA,
Marco

No, 3.3.2 is pretty well closed (and should be available by the end of Feb).

If your control has focus but the FocusControlSourceProvider is not
providing that variable that's a bug (of some kind). Please open a bug
report at
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Platform &component=UI&short_desc=[Services]

It can't be fixed in 3.3.2 but it should be fixed in 3.4

Later,
PW
