Hi:
This is for JIRA TRINIDAD-2038, please let me know your suggestion.
There are cases that exception is thrown in update model phase, like
model layer validation failure, by model outside of JSF and the
exception is also handled and reported outside of JSF. To avoid the
component's local value getting reset to null, JSF needs to be notified
when it happens. The proposed solution is to re-throw a special
exception to JSF to notify it and also let JSF know whether it needs to
report the exception.
Here is the interface of the exception:
package org.apache.myfaces.trinidad.context;
/**
* Interface for exceptions that tells whether the exception needs to
be reported.
* If an exception is thrown during JSF lifycycle and aleady reported,
then it should let
* JSF know not to report it again.
*
*/
public interface Reportable
{
/**
* Return false if JSF doesn't need to report this exception,
otherwise true.
*/
public boolean isReportingMessage();
}
Thanks,
Hongbing
