Subject Re: Correct Prepopulate Method
Date Fri, 11 Mar 2005 16:35:39 GMT
You would usually do prepopulation in a setup form.  Which scope you
place the form in depends on how you configure the action that the
form will be submitted to.  For example, if you have "/"
and "/", where submitForm is configured as:

<action path="/submitForm" name="myForm" ...>....</action>

Then in the action for showPage, you'd:

    ModuleConfig moduleConfig =
    FormBeanConfig formBeanConfig = moduleConfig.findFormBeanConfig("myForm");
    DynaActionForm myForm = (DynaActionForm)
    request.getSession().setAttribute("myForm", myForm);

If you want to use request scope, change /submitForm to:
<action path="/submitForm" name="myForm" scope="request"...>....</action>

then in showPage:
    request.setAttribute("myForm", myForm);
