[ http://mc4j.org/jira/browse/STS-377?page=all ]
Ben Gunter resolved STS-377.
----------------------------
Fix Version/s: Release 1.5
Resolution: Fixed
If value is null, the attribute is removed from the map. This makes sense. If
the desired value is an empty string, then an empty string should be passed to
set(...).
> Invoking HtmlTagSupport#set with a null value doesn't clear the attribute

> Key: STS-377
> URL: http://mc4j.org/jira/browse/STS-377
> Project: Stripes
> Issue Type: Bug
> Components: Tag Library
> Affects Versions: Release 1.4.3
> Reporter: Levi Hoogenberg
> Assigned To: 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).
