Chris,
You seem to be using template strings without any reason. Just write
ordinary Xtend with var if, else etc. directly instead of embedding it
within ''' and escaping with << and >>
def Foo(String filterPath, String filterName) {
var fullFilterName = ""
if (filterPath.length() > 0)
fullFilterName = filterPath + "." + filterName
else
fullFilterName = filterName
...
}

The reason why I used Templates is:
When trying to mix Templates into the Xtend Code, the Error "This expression is not allowed in this context, since it doesn't cause any side effects." tends to occur.
Am I not allowed to use Templates within a for-Loop?
for(use : monitor.use)
{
if(use.measinstance != null)
{
'''«printAllFiltersMeasinstance(use.measinstance.type, use.measinstance.name, suffix)»''' << Causes the Error
}
}
