I have composite projects setup in my workspace and I am encountering the same problems and more:
1. Hitting windows file path limits
2. SoapUI does not copy over non-source files (.xls data source files for instance) to the new composite folders.
3. Any attempt to re-locate data sources to reside outside of the composite project (a measure taken to prevent future issues like this) results in an error: Unexpected record type (org.apache.poi.hssf.record.StringRecord)
Not to mention the headache of having to incorporate changes to file names and folder structure into my source repository.
Any assistance in resolving my issues would be appreciated. In the meantime I will remain with 5.0.0
