-----------------------------
Assign To: Craig McClanahan (was: Struts Developer Mailing List)
> logic:iterate doesn't accept primitive values
> ---------------------------------------------
>
> Key: STR-472
> URL: http://issues.apache.org/struts/browse/STR-472
> Project: Struts Action 1
> Type: Improvement
> Components: Taglibs
> Versions: Nightly Build
> Environment: Operating System: All
> Platform: All
> Reporter: Martin Rose
> Assignee: Craig McClanahan
> Priority: Minor
> Fix For: 1.1 Family
> Attachments: primitiveIterate.diff
>
> The struts logic:iterate tag doesn't except arrays of primitives to iterate
> over. I've included a relatively simple patch that allows this, and makes
> the
> logic:iterate tag much more intuitive and complete as it will handle
> collections and arrays of anything appropriately.
> Could a person with access to the tree PLEASE COMMENT on this to me either
> publically or privately, as I would like to do my best to see this included
> in
> the 1.1.x release.
