Issue
Niagara R2 GCM driver version 2.304.522 may generate errors when uploading VEO information.
Environment
Niagara R2 GCM driver version 2.304.522
Cause
This error is generated if there are attributes in VEO## list but there is no LABEL block associated with this VEO.
Resolution
There is a CreateVeoGxPages button located on the Block List Manager screen. This feature is intended to upload the GCM's View/Edit/Override information and generate the appropriate display screens. This function uploads the VEO information successfully, however it may fail to complete the process and generate a "NullPointerException".
To work around this error, create LABEL blocks in the GCM for each VEO used. Make sure to properly name each LABEL block starting with VEO and ending with 01 to 10.
It is also possible a "ClassNotFoundException" will be generated during this upload process. This error is caused by the attribute types found in the VEOs uploaded. The GCM driver can only handle AV and DV types in the list. Any other types in the list will cause this error.
To eliminate the error all non AV or DV attributes must be removed from the VEO attribute list(s) in the GCM.
