Eddie O'Neil updated BEEHIVE-749:
---------------------------------
Assign To: (was: Eddie O'Neil)
> No way to pass a nullable value through netui-data:callPageFlow
> ---------------------------------------------------------------
>
> Key: BEEHIVE-749
> URL: http://issues.apache.org/jira/browse/BEEHIVE-749
> Project: Beehive
> Type: Improvement
> Components: NetUI
> Versions: v1m1
> Reporter: Rich Feit
> Priority: Minor
>
> I've got the following in a JSP, where "${requestScope.mayNotExist}" may
> evaluate to null:
> <netui-data:callPageFlow method="doit" resultId="result">
> <netui-data:methodParameter value="${requestScope.mayNotExist}"/>
> </netui-data:callPageFlow>
> This produces the following tag error when the value is null:
> "The MethodParameter tag must have either the isNull attribute set to
> true or the value attribute set to a valid value."
> That's OK, but since null is a valid value for the argument to 'doit', I want
> to do this:
> <netui-data:methodParameter value="${requestScope.mayNotExist}"
> null="${requestScope.mayNotExist==null}"/>
> This violates the 'databindable' flag on that attribute ("According to TLD or
> attribute directive in tag file, attribute null does not accept any
> expressions"). Seems like there's no easy way to pass a nullable value to a
> method...?
