Subject Re: Passing a List through a hidden field
Date Wed, 23 Apr 2008 23:36:16 GMT
Thanks Gabriel and Jeromy,

I had thought of iterating through the List but was trying to avoid
generating a mass of HTML hidden fields.

I like it how the hidden tag translates the List into a meaningful
String, it's just a shame that Struts/XWork doesn't handle it when the
form is submitted.

I have raised an Improvement request on the JIRA
(https://issues.apache.org/struts/browse/WW-2612) and will continue to
investigate a way around this.  If anyone else has some bright ideas
it would be more than welcome.

Regards,
Steve
