Make the
org.apache.tapestry.services.impl.ExpressionEvaluatorImpl.createContext()
method public/protected
----------------------------------------------------------------------------------------------------------
Key: TAPESTRY-906
URL: http://issues.apache.org/jira/browse/TAPESTRY-906
Project: Tapestry
Type: Improvement
Components: Framework
Versions: 4.0.1
Reporter: B.S.Navin
Priority: Minor
I have my own OGNL property accessor to handle nulls in my object graph. But I
have some logic in it, which needs to know if the root ognl operation was a
set/get.
OGNL provides a feature called "traceEvaluations" in which we call
"setTraceEvaluations(true)" on the OgnlContext and the property accessor is
provided with the evaluation. Using this evaaluation, it is possible to find if
the root ognl operation was a set/get.
Tapestry creates the OgnlContext in the
org.apache.tapestry.services.impl.ExpressionEvaluatorImpl.createContext()
method. As it is currently private, I had no choice but to duplicate the class
source in my own class, add the required line and replace it as the
implementation of the ExpressionEvaluator service.
It would be good if it is made protected/public. Then I can subclass it /
intercept the createContext() method and do my stuff.
