I found the following advice in the struts archive regarding a "tag within a tag" problem: ---------------------------------------------------------------------------------------------------- From: John Raley Subject: Re: nesting bean:write inside of html:link Date: Mon, 27 Aug 2001 13:22:41 -0700
As a workaround, I wrote an 'eval' tag that captures its content to a bean. You can bind the content to a scripting variable and use the variable. It's ugly but it works. So, you'd do this: <x:eval id='idValue'><bean:write name="somebean" property="id" /></x:eval> <html:link href="somepage.jsp?action=someaction&id=<%= idValue %>" >link text</html:link> The actual implementation of eval is very simple - just a body tag that captures its content to a String and puts the String into the page context. ---------------------------------------------------------------------------------------------------- John's example implies that the tag somehow puts the <x:eval> id attribute, "idValue", into the pageContext such that it can be accessed from the scriptlet <%=idValue%>. In my implementation, the best I can do is set "idValue" as the name in the pageContext.setAttribute() method. Then the jsp page has to get it like so: <x:eval id="idValue"><bean:write name="somebean" property="id" /></x:eval> <%String idValue= (String) pageContext.getAttribute( "idValue" ); %> <html:link href="somepage.jsp?action=someaction&id=<%= idValue %>" >link text</html:link> Is John's example just pseudo code that leaves out the pageContext.getAttribute step, or is there some way to set a variable in a custom tag such that it can be directly accessed from a scriptlet? Thanks, Craig R.
