Re: S2 tags - dynamic attributes
More like... Ah... hrm. Tell 'em look at the TLD, then tell 'em to check the freemarker template, then tell 'em they might have to escape the attribute. I love Java.

S2 tags - dynamic attributes
What I need to do is very simple, but I'm beginning to wonder whether Struts2
actually lets me do it.
Firstly, I want the id attribute of any HTML tag to take a dynamic value, so
that I can code it at runtime.
Secondly I want the tag to take e.g. dojoType as an attribute:
s:iterator value=#xxx status=itStatus var = yyy
s:radio dojoType = zzz id = #{itStatus} list=#{'0':'', '1':'',
'2':'', '3':'', '4':'', '5':''}
/s:radio
s:iterator
Neither of these work.
If I can't do this (or use a simple workaround), I cannot use Struts tags.
Is it possible?

(1) Your OGNL expression for the id attribute is incorrect, plus you need to
force evaluation for id:
id=%{#itStatus.index}
Or .count, if you want it starting at 1. See [1,2].
(2) You can't just randomly add attributes to JSP tags... Depending on what
your actual needs are you may be able to get by with an onclick handler and
some JavaScript.

Re: S2 tags - dynamic attributes
1) It can't see why not. BTW, id=#{...} doesn't work because the
expresions start with %, like in id='%{itStatus}'
2) Extrange enough, I tested this with S2.1.2: It works with
s:select but it doesn't work for s:radio.

RE: S2 tags - dynamic attributes
Also, as far as dynamic attributes is concerned, some tags accept them,
some don't. This was added at some point. I looked at s:radio and I
don't think it does. If you find an instance where you think support for
dynamic attributes should be added, file a JIRA. It's not particularly
difficult to put them in, but at the same time, it's not trivial. So,
file a JIRA (preferably with a patch) and it will make its way in.

...and adding this line to the radiomap.ftl file:
#include /${parameters.templateDir}/simple/dynamic-attributes.ftl /
should suffice I think.
However, I would like to know what kind of visual effect or
functionality the dojo library adds to the radio button (I can't find
the dojo 0.4.3 documentation right now.)
2008/9/3 Wes Wannemacher [EMAIL PROTECTED]:
It's a mix of both... There is a @StrutsTag attribute
(allowDynamicAttributes=true) that will tell the TLD generator to add
the appropriate parameter to the tag's entry in the TLD file. However,
it is essentially useless unless you are going to do something with
them. As mentioned in the OOOP, the s:select tag will take extra
attributes, but s:radio doesn't. If the TLD file declares
dynamic-attributestrue/dynamic-attributes for a tag, the tag's class
must implement the DynamicAttributes interface as well.

I'm thinking there is none. I was on a bit off on a tangent...
If the original poster makes a good case for adding dynattribs to
s:radio though (in a JIRA) I wouldn't see why it couldn't be done.
