Build Identifier: 20110301-1815 If a MultiEditor is started using a extension point of org.eclipse.ui.editors using a concrete MultiEditor class and a file as input leads to a ClassCastException because the MultiEditor expects a MultiEditorInput. More precisely, the EditorReference calls the method openMultiEditor(...) of the EditorManager and there is never any method triggered of the MultiEditor where it is possible to change the input. This problem can be bypassed if you are using an IEditorLauncher where you can change the the FileEditorInput to MultiEditorInput. An easier way would be if the EditorReference would check the IEditorInput and if the part is a MultiEditor but the editorInput not a MultiEditorInput that it would call a method editorInput=((MultiEditor)part).convertInput(editorInput) and to extend the MultiEditor by abstract public IEditorInput convertInput(IEditorInput input) which returns a MultiEditorInput. Reproducible: Always
The javadoc needs to be updated on MultiEditor that a MultiEditorInput needs to be supplied (it has always worked this way and I thought that it was documented, but I can't see it in the doc) PW
