Error trying to remove widget while importing

[alon24]

Hi all,

I am writing my own STVI tools.
I am trying to do some cleanup after I broke some child parent relationship, and clean house.
I am trying to do RemoveWidget but it fails with the following error:

private static void removeLeftOvers()
        throws InvocationTargetException
    {
        ArrayList lst = new ArrayList();
//        Object[] widgets =(Object[]) SageApi.Api("GetAllWidgets");
//        int size = SageApi.IntApi("Size", new Object[]{widgets});
//        log("all widgets = " +widgets+", " + size);
//        log("children size = " + size);
        List imported = Arrays.asList((Object[])_importedWidgets);
        for (Iterator iter = imported.iterator(); iter.hasNext();)
        {
            Object widget = (Object) iter.next();
            Object[] parents =(Object[]) SageApi.Api("GetWidgetParents", new Object[]{widget});
//            log("checking " + widget);
            if (parents.length>0)
                continue;
 
            ImportAction act = isImportActionsWidgets(widget);
            if (act != null)
            {
                lst.add(widget);
                log("found to delete " + widget);
            }
        }
 
        for (Iterator iter = lst.iterator(); iter.hasNext();)
        {
            Object widget = (Object) iter.next();
            log("the widget to del = " + widget);
            SageApi.Api("RemoveWidget", new Object[]{widget});//line 109
        }
    }
