Hello!
I'm getting a error with LCDS 3.1.0.315496
I'm using a DataService to edit some entities with
dataService.autoCommit = false;
I fill a arrayCollection like:
dataService.fill(entitiesAC); //fill with all entites
If i want to update a entity i do:
dataService.commit([entitiy]); //works fine
If i want to create a entity i do:
dataService.createItem(entity);
dataService.commit([entity]); //works fine
If i want to undo my made changes i do:
dataService.revertChanges( entity ); //works fine
If i want to delete a entity i do:
dataService.deleteItem( entity );
dataService.commit( [entity] );
In this case the entity will be deleted, but i get this ugly flex error:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at mx.data::DataList/getItemIndex()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\DataList.as:376] at mx.collections::ListCollectionView/getFilteredItemIndex()[E:\dev\4.x\frameworks\projects\framework\src\mx\collections\ListCollectionView.as:710] at mx.collections::ListCollectionView/addItemsToView()[E:\dev\4.x\frameworks\projects\framework\src\mx\collections\ListCollectionView.as:1102] at mx.collections::ListCollectionView/listChangeHandler()[E:\dev\4.x\frameworks\projects\framework\src\mx\collections\ListCollectionView.as:1284] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.data::DataList/internalDispatchCollectionEvent()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\DataList.as:2296] at mx.data::DataList/internalDispatchOneAddRemoveEvent()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\DataList.as:2285] at mx.data::DataList/http://www.adobe.com/2006/flex/mx/internal::applyUpdateCollectionRangeIndex()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\DataList.as:1920] at mx.data::DataList/http://www.adobe.com/2006/flex/mx/internal::applyUpdateCollection()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\DataList.as:1703] at mx.data::DataList/http://www.adobe.com/2006/flex/mx/internal::applyPendingUpdateCollections()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\DataList.as:1466] at mx.data::DataList/http://www.adobe.com/2006/flex/mx/internal::processUpdateCollection()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\DataList.as:1634] at mx.data::ConcreteDataService/http://www.adobe.com/2006/flex/mx/internal::processUpdateCollection()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\ConcreteDataService.as:4683] at mx.data::DataStore/http://www.adobe.com/2006/flex/mx/internal::commitResultHandler()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\DataStore.as:2264] at mx.data::CommitResponder/internalProcessResults()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\CommitResponder.as:559] at mx.data::CommitResponder/processResult()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\CommitResponder.as:487] at mx.data::CommitResponder/result()[C:\depot\DataServices\branches\hotfixes\lcds31_hotfixes\frameworks\projects\data\src\mx\data\CommitResponder.as:228] at mx.rpc::AsyncRequest/acknowledge()[E:\dev\4.x\frameworks\projects\rpc\src\mx\rpc\AsyncRequest.as:84] at NetConnectionMessageResponder/resultHandler()[E:\dev\4.x\frameworks\projects\rpc\src\mx\messaging\channels\NetConnectionChannel.as:547] at mx.messaging::MessageResponder/result()[E:\dev\4.x\frameworks\projects\rpc\src\mx\messaging\MessageResponder.as:235]
I don't get any error if i do
dataService.deleteItem( entity );
dataService.commit( ); //but this also will commit unsaved changes in other entities
Thanks for your help
