Bug 116706 Bad Class Cast in IDEReportEditor.java
So I'm trying to open a report with BIRT/Eclipse API using the BIRT 2.0 nightly build code (as of 11/16/2005). the file IDEReportEditor.java method private IFile getFile( IEditorInput input ) { return ( (ReportFileEditorInput) input ).getFile( ); } However, input can be ReportEditorInput which is also an IEditorInput (to support reports found outside projects and workspaces) which doesn't even have a getFile() method on it. This causes a deeply nested exception that causes the report desinger to not be able to show a report that might be physically located outside a workspace.
UI/org.eclipse.birt.report.designer.ui.editors.schematic/src/org/eclipse/birt/report/designer/ui/editors/pages/ReportXMLSourceEditorFormPage.java
if ( type == PROP_DIRTY )
		{
			if ( editor != null )
			{
				markPageStale( IPageStaleType.CODE_CHANGED );
				editor.editorDirtyStateChanged( );
			}
		}
		else
		{
			super.firePropertyChange( type );
		}
	}
	/*
	 * 
	 */
	public Object getAdapter( Class required )
	{
		if ( required.equals( ActionRegistry.class ) )
		{
			if ( registry == null )
			{
				registry = new ActionRegistry( );
			}
			return registry;
		}
		return super.getAdapter( required );
	}
}
