Problem: During MBO development, if the data volume is large, for example, either a large number of rows, or a large object in the returned result, Unwired WorkSpace may run out of memory and fail when you click Preview or Test Execute.
To avoid these errors, either do not select the Preview or Test Execute options, or increase the Java VM arguments -Xss -Xms, and -Xmx in UnwiredWorkSpace.bat to increase the stack and memory (heap) size.
