RE: id attribute

[van Hilten, Clive]

Actually, on reading my reply again, I think we are talking about different
things altogether - I see that you are trying to have the attribute _name_,
not its _value_, determined at runtime - no idea about this, sorry.

Here is an example of something I have along the lines you suggest. It is a
JSP that generates WML code to be viewed in a WML browser on a mobile
device. The JSP container I am using is Tomcat 3.2 on Windows 2000
Professional. It compiles just fine. The custom tag library I am using is
the Openwave Usability Interface (OUI).

Hi all,

Does anybody know what a JSP container is supposed to do when an 'id'
attribute of a custom tag is specified through a run-time expression
value? For example:

in mytaglib.tld

<tag>
   <name>mytag</name>
    ....
   <attribute>
        <name>id</name>
        <rtexprevalue>true</rtexprvalue>
   </attribute>
</tag>

and then in a JSP:

<mylib:mytag id='<%= someFunction() %>'/>


I know the intent of the 'id' attribute is to be specified at
translation time, but if no scripting variable is created why not have
an id that takes one its value dynamically?

Thanks in advance,
Boris
