Description

LiveCycle DataService has lazy loading feature where the property of an object isn't loaded until the client access it. When the client access it, LCDS throws an ItemPendingError and fetch data from server. I have a main datagrid, and a second datagrid is inside tabnavigator. This second datagrid dataprovider databind to first datagrid selectedItem.lazyLoadedProperty. If I selected the tab which contain the datagrid before I select an item from first datagrid, it works. If I selected the item on the first datagrid before the tab, I get an error
Steps to reproduce:
1.install LCDS (please contact wichan for installation instruction if needed
2.use lcds war
3.replace data-management-config.xml in WEB-INF/flex
4.compile java source with -cp flex-messaging-data.jar(can find in WEB-INF/lib) into WEB-INF/classes
5. compile testLazyTab.mxml using -services=WEB-INF/flex/services-config.xml -context-root=lcds
6. run compiled swf
7. click fill and wait the datagrid to be filled
8. select an item on the datagrid
9. select the lazy Children tab
