Hi all,

I just started to develop my first query with the modsico query manager. I
followed the examples I found in the help menu. However, there seems to be a
bug in the indigo release. When I want to create a query to my query set,
the parent query set field remains empty. I exactly followed the
instructions in the help sections.

Any suggestions on this?

Hi,

I couldn't reproduce your problem. When I created a query set and then opened the create query wizard, the query set appeared in the "parent query set" list.

Does your query set have errors? Does it appear in the "Query Sets" view?
You can try doing a "Project > Clean..." on the project containing your query set to force the query set catalog to recompute its state.

I guess the problem was related to the fact that I did not create the query
set within a dedicated MoDISCO project. Is this a bug or a feature?

Anyway, I plan to use the CustomizableContentProvider and -LabelProvider
from MoDISCO for my metamodel browser to allow users a more fine-grained
customization. Shall I have to take anything else into account except those
two classes?

I'm a bit puzzled due to the fact that query set apparently only work within
modisco projects.

Best Regards,

Timothy

This is by design : the QuerySet catalog is filled with query sets found by an Eclipse builder that is only defined on MoDisco projects (i.e. projects that have at least the MoDisco nature and builder, but may have additional natures and builders).

Yes, you must also instantiate a CustomizationManager and pass it to the providers.
And depending on the customizations you are using, you may have to call CustomizationManager#installCustomPainter on your tree control, to install a painter that draws customizations that can't be displayed natively with JFace.

see:
http://wiki.eclipse.org/MoDisco/Components/ModelBrowser/Architecture
You may also want to look at this project, which uses the customizable content and label providers:
http://dev.eclipse.org/svnroot/modeling/org.eclipse.mdt.modisco/examples/trunk/org.eclipse.gmt.modisco.infra.browser.uicore.examples.cnf

Please note that you can also deploy/install plug-ins that contain query sets registered through an extension point (org.eclipse.gmt.modisco.infra.query.registration).

Thanks a lot for your prompt reply. I guess I will have to take a look into
Papyrus, since they've done it quite well.
