struts-el tags overwrite property values

           Summary: struts-el tags overwrite property values
           Product: Struts
           Version: 1.1 RC1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Custom Tags
        AssignedTo: struts-dev@jakarta.apache.org
        ReportedBy: michael@mage.net


for example, in struts-el:text, if you have a property that is set to an
expression, like ${i}, then the tag evaluates the expression and then stores the
result in the property setting. if the tag is reused (as per the jsp 2.3 spec),
then the expression will not be reevaluated. this is a particular problem for
looped html form elements. this won't show up in some servlet containers because
they don't recycle tags. the problem doesn't happen in tomcat, but does happen
in caucho resin.

the fix seems simple; instead of calculating and overwriting the properties in
doStartTag(), just have the individual getters return evalExpr(the property
value). there are other, more invasive, solutions, of course.
