RE: Random tag library - dynamic range

First of all, thanks Kris.

Sadly though, it didn't work. 

I keep getting the same error, even though I changed the TLD:
/WEB-INF/tags/scene4.tag(124,2) According to TLD or attribute directive in
tag file, attribute range does not accept any expressions

Looking at the docs
(http://jakarta.apache.org/taglibs/doc/random-doc/index.html), it doesn't
appear that the taglib really supports request-time attr values. Strange.
Personally, I'd grab the TLD and change this:

<tag>
    <name>number</name>
    ...
    <attribute>
      <name>range</name>
      <required>no</required>
      <rtexprvalue>no</rtexprvalue>
    </attribute>
    ...

to this:

<tag>
    <name>number</name>
    ...
    <attribute>
      <name>range</name>
      <required>no</required>
      <rtexprvalue>yes</rtexprvalue>
    </attribute>
    ...

and see what happens...
