aharui commented on issue #654: TypeError: Cannot read property 'length' of null (dbzUtil) URL: https://github.com/apache/royale-asjs/issues/654#issuecomment-571387839 PickList.mxml appears to have two ways of setting the dataProvider. One is in the handleResult which looks correct, the other is in the mx:AdvancedDataGrid tag where it binds to arrDGDataProvider which appears to be incorrect as handleResult is expecting an ArrayCollection of ArrayCollections. ``` dataProvider="{arrDGDataProvider}" ``` This causes the labelFunction to throw the exception as it is getting an ArrayCollection instead of the list of items.
