Html Buttons & DynaValidator Forms

[Mike Young <mi...@e-mage.com.au>]

Hi,

I am trying to implement antonio lagnada's  html buttons 'pattern'
(http://j2ee.lagnada.com/struts/html-buttons.htm) with DynaValidatorForms
however I am have problems in the Action form when I try to interrogate
the getters to find which button has been pressed.

I am fairly new to struts so I may have interpreted how to implement this
'pattern' with DynaValidatorForms incorrectly, and would really appreciate
some direction.

here is where my problem lies ... I have my action 'AddTrainer' as follows
...

public ActionForward execute(ActionMapping mapping,
                             ActionForm     form,
                             HttpServletRequest request,
                             HttpServletResponse response){

  ActionForward forward = mapping.getInputForward(); AddTrainerForm
  addTrainerForm = (AddTrainerForm) form;

  String foo = (String)addTrainerForm.get("buttons.submit.name");
---snip----
At this point it stack dumps because property buttons.submit.name doesn't
exist. I have toyed with the idea of creating it as a form-property but I
don't think that this is right.

I understand that when submit is pressed 
---snip----
<html:submit property="buttons.submit.name">Submit</html:submit>
---snip----

It will carry out a getButtons().getSubmit().setName("Submit")

But how do I interrogate that setter when I am using dynamic forms?

Here is the other bits of pertiment code ...

strus-config.xml
---snip----
<form-beans>
       
  <form-bean name="addTrainerForm"
  type="com.struts.addtrainer.AddTrainerForm">
    <form-property name="tnrId" type="java.lang.String"/> <form-property
    name="tnrFirstname" type="java.lang.String"/> <form-property
    name="tnrSurname" type="java.lang.String"/>
  </form-bean>
			
</form-beans>
---snip----
<action path="/addTrainer"
  input="/jsp/addTrainer.jsp"
  name="addTrainerForm"
  scope="request"
  validate="true"
  type="com.struts.addtrainer.AddTrainer"> <forward
  name="addtrainer.cancel" path="/app/homePageSetup"/> <forward
  name="addtrainer.success" path="/app/trainerDetailSetup"/>
</action>
---snip----

Created HtmlButton class as per example in url metioned above

Created AddTrainerButtons as per example in url mentioned above
{ExampleButtons.java}

Modified my AddTrainerForm as follows ...

public class AddTrainerForm extends DynaValidatorForm
 private AddTrainerButtons m_buttons = null;
---snip----
 public void reset(ActionMapping mapping, HttpServletRequest request)
    {
        ActionServlet servlet = super.getServlet(); m_buttons = new
        AddTrainerButtons();
    }
---snip----
 public AddTrainerButtons getButtons() {
  return m_buttons;
 }
 }
 public void setButtons(AddTrainerButtons buttons) {
  m_buttons = buttons;
 }
---snip----

thanks to anybody and everybody who may be able to help my understanding
of this!
