Replacing property tab did overwrite all model objects? [message #1691158]

Hi,

I created a custom Task model element wich extends the standard task model element (see the CustomTask Tutorial)
Next I tried to configure one of my custom propertySections to replace one of the default tabs of the Task element when my CustomTab element is selected:

<propertyTab
            class="org.imixs.bpmn.ui.process.ProcessApplicationPropertySection"
            id="org.imixs.bpmn.propertytab.application"
            label="Application"
            replaceTab="org.eclipse.bpmn2.modeler.task.tab"
            runtimeId="org.imixs.workflow.bpmn.runtime"
            type="org.eclipse.bpmn2.Task">
</propertyTab>

This works. But now also for all other Task Model Objects the default 'Task' tab is hidden.

My goal was just to replace this tab if my customTask was selected.
Is it possible to configure this or to overwrite this behavior?

Thanks for help

Hi Ralph,

I think it IS possible to do this within the current API somehow. I'll let you know what I find out....

OK, try this:

Override the method public boolean doReplaceTab(String replacedId, IWorkbenchPart part, ISelection selection) in your ProcessApplicationPropertySection class. In there you will have to examine the business object associated with the selection and determine if you want the tab to be replaced. You can use this:

		EObject businessObject = BusinessObjectUtil.getBusinessObjectForSelection(selection);

to get the business object.

I haven't had a chance to test this out, so let me know if this works!

Cheers,
Bob

Hi Bob,

yes this works. Thanks!

	@Override
	public boolean doReplaceTab(String id, IWorkbenchPart part,
			ISelection selection) {

		EObject businessObject = BusinessObjectUtil
				.getBusinessObjectForSelection(selection);

		EStructuralFeature feature = ModelDecorator.getAnyAttribute(
				businessObject, "processid");
		if (feature != null && feature instanceof EAttribute) {
			if (ImixsRuntimeExtension.targetNamespace
					.equals(((EAttributeImpl) feature).getExtendedMetaData()
							.getNamespace())) {
				return true;
			}
		}

		return false;
	}

I will add this into the tutorial...
