Re: [e4-dev] Horizontal extension possibility for e4 tooling
|
https://git.eclipse.org/r/#/c/18813/
I found a „minimally invasive“ solution, which I do not really like, so I hope for a better proposal:
I extended my classes in general by giving them dependency injection, and if one extends the MApplication.class
and has a method with @Persist in it, it gets called by the „parent“ so one can handle oneselves persistence.
==== ModelEditor:line 1366
@Persist
public void doSave(@Optional IProgressMonitor monitor) {
try {
setSaving(true);
if (modelProvider.isSaveable()) {
modelProvider.save();
List<AbstractElementEditorContribution> aeec = getTabContributionsForClass(MApplication.class);
for (AbstractElementEditorContribution aeecChild : aeec) {
try {
ContextInjectionFactory.invoke(aeecChild, Persist.class, context);
} catch (InjectionException e) {
// ignore
}
}
}
} finally {
setSaving(false);
}
}
