I need help figuring out how to generate and use dynamic forms with Struts.
Is there already an eloquent MVC solution in Struts?
Is DynaActionForm the answer?
I can't see how extending the ActionForm behavior accomplishes this. It
seems that to really implement a dynamic form, the form Bean would need to
be defined and instantiated at run-time, based on the HttpResponse generated
by the forms JSP.
For example:
Say the JSP for looks like the following:
<%-- myDynamic.jsp --%>
<html:form action="/work">
<logic:iterate id="y" name="a" property="b"/>
<html:text>
property="x-"<bean:write name="y" property="z"/>
</html:text>
</logic:iterate>
</html:form>
This will not work since "property" is required in the <html:text> tag.
However, if it did work, then it seems there would need to be some Action
that gets the HttpResponse from "myDynamic.jsp" and generates the source
(Java) form definition, e.g.:
// MyDynamicAction.java
...
for(Iterator i = A.iterator(); i.hasNext;)
a = i.next();
buffer.append("public setX-" + a.getB() + "(String s) { ");
buffer.append(" x-" + a.getB() + " = s ;");
...
And, then compiles and instantiates it.
Does this make any sense, whatsoever? If I'm completely lost, then someone
please try and help point me in the right direction.
Thanks,
