    Attachment:     (was: cheap-levitra.html)

> Invoking HtmlTagSupport#set with a null value doesn't clear the attribute
> -------------------------------------------------------------------------
>
>                 Key: STS-377
>                 URL: http://www.stripesframework.org/jira/browse/STS-377
>             Project: Stripes
>          Issue Type: Bug
>          Components: Tag Library
>    Affects Versions: Release 1.4.3
>            Reporter: Levi Hoogenberg
>            Assignee: Ben Gunter
>            Priority: Minor
>             Fix For: Release 1.5

> It's not possible to clear attributes of tags that extend from 
> HtmlTagSupport. Most (all) attribute setters delegate to set (String, 
> String), which always puts a value in the attribute map (which in turn causes 
> writeAttributes to actually print the attribute). IMO set should look 
> something like
>     protected final void set(String name, String value) {
>         if (value == null) {
>             this.attributes.remove(name);
>         } else {
>             this.attributes.put(name, value);
>         }
>     }
> I noticed this behaviour with DefaultTagErrorRenderer, when my labels started 
> looking like
>     <label class="null" for="password">Password:</label>
> (caused by Tomcat 6.0.10s tag pooling mechanism).
