java.lang.IllegalArgumentException: Cannot determine the graph element type because the document class is null.

Hello I'm creating a widget for Samsung Gear. Im using Tizen IDE for wearable. I followed their youtube tutoria: How to Create a Basic Integrated Gear Application.

I tried Build Project in Tizen IDE and there was a build error:

Errors occurred during the build. Errors running builder 'Web Widget Builder' on project 'SimpleSAPConsumer'. Build Error : Cannot determine the graph element type because the document class is null. Probably this is a projection, use the EXPAND() function Build Error : Cannot determine the graph element type because the document class is null. Probably this is a projection, use the EXPAND() function

Then Error Log said:

eclipse.buildId=
java.version=1.7.0_67
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en
Command-line arguments:  -os win32 -ws win32 -arch x86_64

Solution

  • There is probably a small spelling mistake or something somewhere because my guess is that there is no 'document' class since it probably doesn't exist in memory or you're referencing a class (Foo dingDong = new Foo(); foo.getStats()) that does not exist in memory.
