Incorrect default expression language for property aliases
----------------------------------------------------------
Key: ODE-638
URL: https://issues.apache.org/jira/browse/ODE-638
Project: ODE
Issue Type: Bug
Components: BPEL Compilation/Parsing
Affects Versions: 1.3.2
Reporter: Mark Ford
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.
