All that means is you can have
<mysimpleTag value="<%=scripletVariable%>"/>
false means you cannot have a scriplet variable as a value
That's not quite what i wanted to do, but in a way accomplishes a similar task without
modifying struts. Its not sexy enough for me ;)
The whole point of MVC is seperation presentation, business logic, code
<html:form
action="<%=request.getAttribute("formaction")!=null?(String)request.getAttribute("formaction"):"/Default/url"%>"
method="post"/>
If i start putting scriptlets like that in my code, im basically breaking the MVC
design pattern. Because now, my JSP page is dependent upon that scriptlet variable
being in the environment, and if it used an object, say like this:
<html:form
action="<%=request.getAttribute("myForm")!=null?(MyForm)request.getAttribute("formaction").getFormaction():"/Default/url"%>"
method="post"/>
The method I used, I believe, is a tad better because the JSP page will still function
in the absence of that scriptlet variable, and is cleaner JSP code.

Mark
