There was a time recently that I discovered that several tag attributes had "rtexprvalue" being true when it should not have been. Most of these should be changed now in the nightly build. As I said, any attribute that specifies the name of a scriptlet variable to create cannot use an rtexprvalue for the attribute value. In general, I believe the name of this tag attribute will be "id". I don't remember if there were any others.
If you can demonstrate a case of an attribute that is reasonable to have an rtexprvalue, but it isn't working, then you should report that as a bug (but you might ask about it first here). -----Original Message----- From: Tom Carey [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 29, 2003 9:52 AM To: Struts Users Mailing List Subject: RE: what does RT Expr mean Just getting in to the mix here.... That's good to know. The Struts taglibs have every attribute set with <rtexprvalue>true</rtexprvalue>. But I found that using an expression scriptlet was inconsistent. It would work for some tags and not for others. Has anyone else experienced that? -----Original Message----- From: Karr, David [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 29, 2003 12:05 PM To: Struts Users Mailing List Subject: RE: what does RT Expr mean A custom tag attribute can only use an expression scriptlet if the attribute specification in the tag library descriptor has a value of "true" for the "rtexprvalue" attribute. This is not the default, because some attributes of some tags will not work if an expression scriptlet is used to specify them. For instance, if an attribute value specifies the name of a scriptlet variable to declare, then that value has to be available at compile time. It won't do any good to wait until run-time to get the value, as that would be too late. -----Original Message----- From: Sundar Narasimhan [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 29, 2003 8:49 AM To: [EMAIL PROTECTED] Subject: Re: what does RT Expr mean Thank you for all your replies. I had guessed RT Expr might mean that. But now for the follow up. >As others have said, it means "run-time expression". Specifically, it >means the value CAN be specified by a JSP expression scriptlet >(beginning with "<%="). Ironically, calling it a "run-time expression" I'm now confused. I've been able to previously put <%= %> in similar places in other JSP's that did not use the struts tags. Are you all telling me that there are now cases when certain tags are marked w/out RT Expr .. that these struts tags explicitly disallow me typing <%= %> in those attributes? If so that would be a step backward IMHO.
