Re: How to open a popup in onSubmit() of a Form

[thomas jaeckle]

Hi again.
I found a solution, but it isn't very nice:

First I implemented a AjaxForm like the AjaxButton is implemented (why isn't
there a AjaxForm delivered with Wicket?):

public abstract class AjaxForm extends Form
{
   public AjaxForm(String id)
   {
      super(id);

      add(new AjaxFormSubmitBehavior(this, "onsubmit")
      {
         private static final long serialVersionUID = 1L;

         protected void onSubmit(AjaxRequestTarget target)
         {
            AjaxForm.this.onSubmit(target);
         }

         protected void onError(AjaxRequestTarget target)
         {
            AjaxForm.this.onError(target);
         }

         protected CharSequence getEventHandler()
         {
            return new
AppendingStringBuffer(super.getEventHandler()).append("; return false;");
         }

         protected IAjaxCallDecorator getAjaxCallDecorator()
         {
            return AjaxForm.this.getAjaxCallDecorator();
         }
      });
   }

   protected IAjaxCallDecorator getAjaxCallDecorator()
   {
      return null;
   }

   protected void onError(AjaxRequestTarget target)
   {
   }

   protected abstract void onSubmit(AjaxRequestTarget target);
}



Now I can do:

AjaxForm form = new AjaxForm("form")
{
   private static final long serialVersionUID = 1L;

   protected void onSubmit(AjaxRequestTarget target)
   {
      PopupSettings popupSettings = new PopupSettings(PageMap.forName("id_"
+ textField.getConvertedInput()),
PopupSettings.RESIZABLE).setHeight(768).setWidth(1024);
      
      PageParameters tmpParameters = new PageParameters();
      tmpParameters.add("id", (String)
partnerSearchTextField.getConvertedInput());

       popupSettings.setTarget("'" + urlFor(PrBrsPage.class,
tmpParameters).toString() + "'");

       final String orgPopupString = popupSettings.getPopupJavaScript();
       int i = orgPopupString.indexOf("return false;");
       String popupString = popupSettings.getPopupJavaScript().substring(0,
i-1);
            
       if (target != null)
       {
          target.appendJavascript(popupString);
          // focusComponent(null) to prevent that the main window regains
focus
          target.focusComponent(null);
       }
   }
};


But I don't really like this solution. If someone has an idea how to make
this nicer, please speak ;)

regards Thomas
