[edgar <ed...@blue-moose.net>]

In the struts-html.tld is <rtexprvalue> set to true for the disabled
attribute?

Subject: Why would disabled="..." not take a runtime expression? The

Greetings all...

I'm trying to control whether or not some form fields are editable using
a custom security tag. So, at the top of the page, I have something like
this:

<%-- Page security --%>
<bean:define id="readOnly" type="java.lang.String" value="false"/>
			
<ngt-security:hasNoPermission deny="deny">
	<bean:define id="readOnly" type="java.lang.String"
value="true"/> </ngt-security:hasNoPermission>

If the deny attribute is anything but null or an empty string, readOnly
is set to "true". Then I try to do this:

<html:select property="priority" styleClass="fullwidth" disabled="<%=
readOnly %>">
	...
</html:select>

What I get back is that the readOnly symbol cannot be resolved...
However, the following tests work:

- <html:select property="priority" styleClass="fullwidth"
disabled="true">
- <%= readOnly %> (On its own... This prints out "true")

This is just strange. According to the documentation, disabled should be
able to take a runtime expression, and I use runtime expressions of the
form <%= someVariable %> all over the palce elsewhere.

Any insight would be greatly appreciated.

Cheers...
