Tim Fennell updated STS-579:
----------------------------
Fix Version/s: Release 1.5
Assignee: Aaron Porter
This is definitely a bug. Tag pooling causes a lot of confusion and it looks
like code was introduced in the 1.5 codebase that cleared tag state set by the
container (which the container assumes will be kept, unmodified, between pooled
uses).
What that code should be doing is:
- clearing any derived or created state variables within the tag that are not
set directly by the container
- preserving any attributes set directly by the container
> multiple <stripes:radio> tags with same name attribute causes NPE

> Seems when I have two radios with the same name, I get NPE. One difference I
> found between 1.4.3 and 1.5rc1 is that all of the attributes except for
> "type" are cleared out in InputTagSupport#doEndTag(). When I remove that bit
> of code, everything seems to work...
