Hi all.
I have a problem with providing an IObservableMap for a list feature.
My viewer needs to update the label when a list of a displayed entry
changes.
The label font will be italic if the list is not empty and normal if the
list is empty.
How can I create an IObservableMap to pass as attribute Map to the
ObservableMapLabelProvider on creation?
For a value property I can do:
EMFProperties.value(FooPackage.Literals.FOO__FOO_VALUE)
.observeDetail(ObservableListContentProvider.getKnownElement s())
But what to do for a list property, e.g. FooPackage.Literals.FOO_FOO_LIST?
If there is no possibility to create a map for that, how can I trigger a
label update when the list of any displayed foo item changes?
Cheers.

Hi Tom.
Sorry for confusion.
I ment that the label font of my tree entry is dependend of a list
feature of the entry.
It is more or less the same problem you have in your "Project
Administration" example application. The label of the viewer in the
ProjectExplorerPart displays the number committers in square brackets.
You pass to the ObservabelMapLAbelProvider the following maps:
IObservableMap[] map = new IObservableMap [4];
map[0] =
EMFProperties.value(ProjectPackage.Literals.PROJECT__SHORTNA ME).observeDetail(set);
map[1] =
EMFProperties.value(ProjectPackage.Literals.PROJECT__COMMITT ERS).observeDetail(set);
map[2] = EMFProperties.value(
FeaturePath.fromList(ProjectPackage.Literals.COMMITTER_SHIP_ _PERSON,
ProjectPackage.Literals.PERSON__FIRSTNAME)).observeDetail(se t);
map[3] = EMFProperties.value(
FeaturePath.fromList(ProjectPackage.Literals.COMMITTER_SHIP_ _PERSON,
ProjectPackage.Literals.PERSON__LASTNAME)).observeDetail(set );
The PROJECT__COMMITTERS is a list feature, but you create a value
property from it. I guess the intention is to trigger a label update
when a committer is added. But this does not work! The label provider
does not get a LabelProviderChangedEvent when you add a committer, the
number of committers in the square brackets stay the same after you have
added a committer. only when the name is edited for example, the number
of committers is updated, as the label provider is triggered with the
PROJECT__SHORTNAME map.
So I guessed that the problem is because you use a value property for
the list feature.
I hope makes the problem a bit easier to understand.
Cheers.

Hi,
Ok. This make sense, I know that this thing is not working but I had no
time to fix it. I'll take a look how I can fix this in my example and
then you can probably copy it :-)
I guess what we'd need is a ValueProperty to observe the size of a List
which shouldn't be too hard to implement.
