You have to be careful of the lifecycle of modeldriven w/ validators, etc...
Your model needs to be created before getModel() is called, so it needs to be created at Action object creation (or in the getModel() method) You need to make sure your ModelDrivenInterceptor is applied before your ParamsInterceptor so your Model is set onto the ValueStack before the parameters are set using the valuestack I think the ModelDrivenInterceptor is the one you're missing. To answer your question: Static-params sets the params set in xwork.xml Params sets the params from the request Hope that helps, Jason > -----Original Message----- > From: Jan-Peter Hagenmüller [mailto:[EMAIL PROTECTED] > Sent: Tuesday, January 06, 2004 7:25 AM > To: [EMAIL PROTECTED] > Subject: Spam:Re: RE: Spam:Re: AW: [OS-webwork] Passing model > from one action to another > > > Hi Jason and all, > > yes indeed, i still have this problem... :-) > > I wan't to do field validation with model driven action > having a model bean as usual... > > - if i provide getModelBean() and setModelBean() in > actionsupport class the model reference will be handled as > normal fields > and fields of the bean can be accessed from jsp or > velocety by 'modelBean.fieldX' ... > - field validation can be done via the action-validation.xml > holding field 'modelBean' via 'visitor' type > and a ModelBean-validation.xml holding the fields of the > bean e.g. via 'required' type > > so everything works fine > > then i tried: > - implementing the ModelDriven interface in actionsupport > class, instanciating modelbean class and implementing > getModel() method > > what does not work is: > - then simply access fields of the ModelBean instance via > the field name like <input type="text" value="<ww: property > name="fieldname" />"> > because while action is performed webwork don't updates > the fields of the bean via its setters and because of this > validation always fails and > says: field errors (requiredstring e.g.) ... > > here some code: > > bean class > ----------------- > public class Identity { > String identityName = ""; > String firstName = ""; > public String getIdentityName() { return identityName;} + > setter public String getFirstName() { return firstName;} + setter } > > Identity-validation.xml > ------------------------------------ > ... > <validators> > <field name="identityName"> > <field-validator type="requiredstring"> > <message>Identitaetsname fehlt</message> > </field-validator> > </field> > ... > </validators> > > do i still need a validating.xml for the AddIdentityAction > action ? if yes, what fields in it? identity's fields or > identity as field via visitor type or both > > AddIdentityAction class > ------------------------------------- > public class AddIdentityAction extends > MyValidatingActionSupport implements ModelDriven { Identity > identity = new CIdentity(); public Object getModel() { > return identity;} public String execute() throws Exception { ... } } > > action mapping in xwok.xml > ------------------------------------------- > <action name="addIdentity" class="AddIdentityAction"> > > what interceptors do i really need ? > > <interceptor-ref name="static-params"/> what does they (or > where can i read about it) :-) > <interceptor-ref name="params"/> > <interceptor-ref name="conversionError"/> > <interceptor-ref name="validationWorkflowStack"/> > <result name="input" type="dispatcher">identityAdd.jsp</result> > <result name="error" type="dispatcher">identityAdd.jsp</result> > <result name="success" type="dispatcher">...</result> </action> > > > thanks for reading up to this line :-) > and hopin someone could help > > jp > > > > > > > > > > > > > 05.01.2004 18:35:13, "Jason Carreira" > <[EMAIL PROTECTED]> wrote: > > >I see Hani's suggestion fixed question 1, are you still > having problems > >with question 2? > > > >Applying field validators for the fields of your Model (or > your Action, > >as they are both on the ValueStack) should work.
