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: Tim Fennell
Priority: Minor
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).
