----------------------------------

Mark any chance you can provide a test case to replicate?  I know it's been a while since you filled the bug.

> If a property alias does not define a query language then the default should be XPath 1.0 as per the WS-BPEL 2.0 spec. BpelCompiler.compile(PropertyAlias) uses the same compileExpr(Expression) call as other expressions so the default language becomes whatever the default is for the process definition or XPath 1.0 if not defined.
> I found this problem by setting a default expression to XQuery in my process def. This results in an error at execution since the XQuery compiler inserts a variable declaration for $ode:pid which doesn't resolve in the property alias context.
> One workaround is to add the queryLanguage attribute to each propertyAlias. Another workaround is to not define a default expression language for the process.
> Time permitting, I'll add a test case or patch at some point.
