Read only tag attributes?
G'day all,
Deployed all the WARs with Orion now - my last instructions should work
perfectly.
However when accessing the registration page I get:
"Error parsing JSP page /registration.jsp line 32
Property 'size' of bean/tag 'org.apache.struts.taglib.TextTag' is read only"
Any Struts / Orion users ever seen it? I've used custom tags under Orion for
ages and this one has me baffled.
Mike

I'll clear this up. I never used the tag. :) I merely was responding to what
I thought might be the problem. Sorry to confuse you.

The oddest thing is that I installed an older version at home last night and
the example didn't die at that point. (Incidentally it threw up trying to
add a mail host). At home I installed the build from the 19th of June (no
read only error), and at work I installed the build from 25th June (has a
readonly error) - what has changed between these two dates with the TextTag?
(Or any of it's superclasses?)
Should give you a big headstart on finding the problem!

I think you're right ... Depending on how Orion chooses to implement bean
introspection, it's entirely possible that it will decide there is no setter
method there (even though there are two of them) and thus decide that the bean
is read-only.
I really should not have two setters -- and I suspect there are problems on some
containers if there is only the "int" version of the setter (which is the way it
really should be). I will do some experiments and try to correct this ASAP.

What's puzzling to me is why Kevin didn't run into this. Are you guys running
the same versions of Orion? How about JVMs?

Hi,
I haven't tried using it myself..Craig is probably the one to ask about
that. I would think only one method is allowed..but it is a taglib, not a
setter method for a javabean, so its possible it is allowed in the taglib
itself.

Kevin,
Already checked this. It has two setSize() methods, one for int's and one
for String's. I have a sneaking suspicion this may be the problem (two
methods) as I know the spec is very vague about whether this sort of
overloading is allowed.
Have you got the text tag working under Orion? If so the above can't be the
problem. What about the struts-example?

I bet the code for the taglib doesn't have a set method in the taglib code
that matches the attribute name. Look at the source of TextTag and see if it
has a setSize() method..it could be mispelled or something. Or, maybe Craig
meant for it to be this way.

I bet the code for the taglib doesn't have a set method in the taglib code
that matches the attribute name. Look at the source of TextTag and see if it
has a setSize() method..it could be mispelled or something. Or, maybe Craig
meant for it to be this way.
