Subject [jira] Resolved: (WW-3306) Null value accepted from action property, but not model property when throwExceptionOnFailure=true
Date Fri, 06 Nov 2009 22:11:13 GMT

Musachy Barroso resolved WW-3306.
---------------------------------

    Resolution: Fixed

Actually the solution was easier than expected, I removed the mentioned code and did some
tuning here and there, and now all your examples work, and the code is generic(existing ognl
and xwork code), no more hand parsing of expressions to see if a part is missing

> In this project, we experiment with setting struts.el.throwExceptionOnFailure=true to
catch errors.
> We use <s:property value="myprop" /> in our JSP.
> Occasionally, the property thus referenced is null. We want struts to insert an empty
string in that case.
> This it duely does, when either struts.el.throwExceptionOnFailure=false or when the property
is from an action object.
> However, if the property is from a model object and struts.el.throwExceptionOnFailure=true,
this bombs out.
