Use code like this to create an instance of the DynaFormBean:
Guy
DynaActionForm accountAdjustmentForm = (DynaActionForm) form;
ConfigHelper configHelper = new
ConfigHelper(getServlet().getServletContext(), request, response);
DynaActionFormClass formClass =
DynaActionFormClass.createDynaActionFormClass(configHelper.getFormBean("acco
untAdjustmentForm"));
if (accountAdjustmentForm == null) {
accountAdjustmentForm = (DynaActionForm) formClass.newInstance();
accountAdjustmentForm.initialize(mapping);
}

Subject: Pre-Setting DynaValidatorForm attributes
Hi!
I have the follow situation:
- I get an Circuit Data Object from a manager
Then I want to edit the Circuit in HTML form, using an DynaValidatorForm
I
don't know to how to do correct set for the propertyes priorly!
How should I set the properties priorly?
I'm tring to do the usual set(key, object), but I get an
NullPointerException on
getter:

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() );
}

Thanks
