> I have created a custom implementation of the FunctionMapper, which provides a custom function I want to use in an email template.
> Now, after I add the reference to this FunctionMapper to jbpm.cfg.xml:
> <bean name="jbpm.function.mapper" class="org.jbpm.jpdl.el.impl.DateFormatFunctionMapper" singleton="true" />
> it will get picked up, but unfortunately, the default Mail class does not use it because it always sets the FunctionMapper to null in the evaluate method (last parameter):
>   String evaluate(String expression) {
>     //...
>     return (String) JbpmExpressionEvaluator.evaluate(expression, executionContext, variableResolver, null);
> this should be :
>     return (String) JbpmExpressionEvaluator.evaluate(expression, executionContext, variableResolver, JbpmExpressionEvaluator.getUsedFunctionMapper());
