What specific strategy are you using (you only say "return to the controller")? Are you "chaining" actions by forwarding to a "setup" (form prepopulation) action from your POST-handling action?

Why can't you do this?
in MyAction.java
String formName = mapping.getAttribute();
request.setAttribute("formName", formName);
Struts.config.xml
On the HTML/JSP page
do all your bean writes according to the value of
<%
String name = request.getAttribute("formName");
foo.MyForm theForm = request.getAttribute(name);
%>
etc.
etc.

No -- changing it to a list makes no difference whatsoever:

for (int ndx = 0 ; ndx < ENTRY_ROW_COUNT; ndx ++) {
ProblemItem a = new ProblemItem();
a.setInteger_value( new Integer(ndx));
entries.add( a );
}
}
private String working_perfectly = "A Value";
public String getWorking_perfectly() {

I still believe that lists work -- it's not lack of belief that's the problem,
it's lack of results. There's some magic involved that, if documented
anywhere is somewhere I have yet to uncover.
Based on the general principal of orthogonality if the get method is properly
invoked (which it apparently is) then the equivalent set method should also
be invoked. That's simply not happening. However, orthogonality aside, if
writing a separate indexed set method would make the problem go away I'd
gladly use it.
Alas, however, that doesn't make the slightest difference. I added two
indexed set methods as you suggested with depressingly familiar results:

ProblemItem pi = (ProblemItem)getEntries().get( ndx );
pi.setInteger_value( iValue );
}

Re: Specifying HTML form names
IIRC, the form tag used to have an attribute so you can specify the form name, though I never used it because I never needed to. It was deprecated and eventually removed.

Re: Specifying HTML form names
Just sharing a simple test I just did.
It looks that you can't have two forms with the same name on one document.
I created a page with two forms with the same name, then checked how the
browser sees them with a quick javascript:
var result = "Forms in this document:\n\n";
for (var i=0; i < document.forms.length; i++) {
result = result + "document.forms[" + i + "]=" + document.forms[i] +
"\n";
result = result + "document.forms[" + i + "].name=" +
document.forms[i].name + "\n\n";
}
alert(result);
There was only one entry for the two similarly named forms. Checking the
fields of the form showed me that only the latest definition of a form with a
given name is recognized.
So, you should probably add a formbean declaration (with a different name)
for your action form, and also add another mapping for the same action. It
can be the same ActionForm and Action object, but would need different
mappings in struts-config.

Specifying HTML form names
I have a JSP with two forms, and they both need to go to the same action. But Struts assumes that the "name" property of the HTML form (e.g. ) should be the same as the name of the associated form bean. As a result, I can't use JavaScript to refer to one of the forms, since they both have the same name. Is this a situation where I need to write my own version of ? Why does Struts make this assumption? Things I've already considered: - Using two different actions with different form beans. This doesn't work, since the JSP needs to refer to the form bean by name (for example, in ). If I use two actions that return the same JSP, they need to use the same form bean. - Combining the two forms into one. This doesn't work in my situation, since the forms need to submit different values for the same fields. - Referring to the forms by number in my JavaScript (e.g. document.forms[0]). This doesn't work, since there may be other forms on the page, which would throw off the numbering. Any ideas?

problem occured while validating form
when validating form,some problems occured. As MVC Model2 suggest,I use a controller to query imformations and store them into javabeans.Then the javabeans is used by the page which contains a form. when the form submits,the form is validated.If some errors occured,struts will return to input page.As the input page need some informations to render the page,so I make the struts return to the controller which queries information required by the input page.some informations may be changed when the form submitted,but the controller doesn't know this. How to solve this problem?
