The fix was primarily to ensure that templated paths with elements that resolved to empty strings, did not lead to the creation of illegal paths in the FileFolderService. An example would be //foo/bar.
Added a Java test case that reproduced the issue.
Added a JavaScript test case that partially reproduced the issue.
Also needed to add extract method in ScriptAction to allow some internal code to be called by subclasses. This had the serendipitous benefit of reducing repeated code. This was a secondary issue whereby parameters set in the renditionDefinition were not being correctly passed from the Script layer to the Java layer.
