Just for close this post I want to say this:
- I had a bug for something stupid I made and I didn't realise what was referred by the exception.
The code that I presented here is the correct one. Since we are in a Action or JSP nested to an Action Form, a bean exists in the correct scope with the respective attribute name.
Thanks anyway.

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
