[Opensource] Problem with ClassValue attribute for TransitionTag

[Brian Chow]

I'm trying to apply a style to the transition submit button generated by 
the TransitionTag tag.

The Expresso Taglib documentation lists ClassValue as an attribute for 
TransitionTag.

I first tried using:

    <expresso:TransitionTag name="processUserInfoUpdate" 
ClassValue="formButton"/>

But this resulted in the exception:

    org.apache.jasper.compiler.CompileException: 
/jsp/member/updateUserInfo.jsp(130,3) Attribute ClassValue invalid 
according to the specified TLD
        ...

I took a look at expresso.tld and found "classvalue" in all lowercase.

When I tried using:

    <expresso:TransitionTag name="processUserInfoUpdate" 
classvalue="formButton"/>

I got the following exception:

     org.apache.jasper.compiler.CompileException: 
/jsp/member/updateUserInfo.jsp(130,3) Unable to find setter method for 
attribute: classvalue
