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/src/org/eclipse/birt/report/designer/internal/ui/util/UIUtil.java
return containElement( input, provider, element );
	}
	private static boolean containElement( Object parent,
			ITreeContentProvider provider, Object element )
	{
		if ( parent == null )
		{
			return false;
		}
		if ( parent == element || parent.equals( element ) )
		{
			return true;
		}
		if ( provider == null )
		{
			return false;
		}
		Object[] children = provider.getChildren( parent );
		for ( int i = 0; i < children.length; i++ )
		{
			if ( containElement( children[i], provider, element ) )
			{
				return true;
			}
		}
		return false;
	}
