I am not sure if I understand you correctly, but I will try.

What you basically need is to create a form bean without actually
invoking the action that claims that it uses it. Did I understand you
correctly?

I use "/planning/circuitEditForm" as a mid tier view action to set some Request Attributes with ArrayList. Those ArrayList have data from the DB tier to help build some combo.
If I didn't have any combo dynamic data to build the form I could simple substitute "/planning/circuitEditForm.do" for "/planning/circuitEditForm.jsp".

But my problem is that beownd the data for those combos I need to set in advantage de value for the bean, so with <html:text property="designation" maxlength="50" /> in the JSP I get the value existing in the database, to do some editing of existing data.

That's why I'm trying to do the code that I gived here. 


Anway to create your form bean manually you would do something like
this:

ModuleConfig mc = RequestUtils.getRequestModuleConfig (request);
ActionMapping am = (ActionMapping) mc.findActionConfig (actionName);
return RequestUtils.createActionForm (request, am, mc, getServlet ());
I'm trying to do this, I'll be back.


where action name is the action name that uses the form you create, in
your case /planning/circuit/edit

I was reading my post and reallise that I omitted an importante
information.
The action where I want to set DynaValidatorForm properties is the one

to

forward into the JSP that builds the all form, and not the action
associated
with the bean.

Just for more complete information:
The actio that contains the initial form bean:
        <action path="/planning/circuit/edit"
            type="com.esegur.sims.web.CircuitEditAction"
            scope="request"
            name="CircuitEditForm"
            input="/planning/circuitEditForm.do"
            validate="true">
            <forward name="ok"

path="site.planning.circuit.edit.result"/>

<forward name="ko"

path="site.planning.circuit.edit.form"/>

</action>


The action where I want to set some properties:
        <action
            path="/planning/circuitEditForm"


type="com.bla.bla.web.formaction.CircuitEditFormJSPAction"

parameter="/planning/circuitEditForm.jsp"/>

BasicDynaValidatorForm is just an helper for getString, getInteger

and

so on.

The code I'm using for setting is:
---
       if (actionForm instanceof BasicDynaValidatorForm ) {
           BasicDynaValidatorForm circuitEditForm =
(BasicDynaValidatorForm)actionForm;

circuitEditForm.initialize(actionMapping);

           CircuitDO cDO =
Planning.getCircuitSessionAttr(httpServletRequest);
           circuitEditForm.set( "circuitId", cDO.getCircuitId() );
/*...*/
           circuitEditForm.set( "designation", cDO.getDesignation()

);

       }
