Swing Browser [message #1396068]

How can I make the browser field work in swing? It works in swt and RAP. I've seen that there is a solution related with fragments but I don't really understand how this works, and I didn't find anything in the forum.
Thanks

Hi Betty,

I did try the browser field with our demo widget app and it works fine in swing:
index.php/fa/18499/0/

Can you provide some more information?

1) Can you paste the java code of the browser part in your project?
2) Which version of Scout are you using?

Best regards,
Matthias

I'm using Luna 32 bits I downloaded it a week before the official release.
The code I'm using is the same that I saw in a forum topic. The weird thing is that it works fine with swt and RAP. In swing it says "placeholder for

@Order(20.0)
      public class BrowserField extends AbstractBrowserField {

        @Override
        protected int getConfiguredGridH() {
          return 10;
        }

        @Override
        protected boolean getConfiguredGridUseUiHeight() {
          return true;
        }

        @Override
        protected int getConfiguredGridW() {
          return 2;
        }

        @Override
        protected void execInitField() throws ProcessingException {
          setLocation("http://www.eclipse.org");
      }

This is the picture
index.php/fa/18501/0/

There are no error messages in the console only the "Placeholder for Browser Field"

Hi Betty,

I just tried with the latest Luna release and I experience the same problem.

Solution:
1) open your swing development product file: In my case it is <my-project>.ui.swing/products/development/swing-client-dev.product
2) Go to Dependencies tab
3) Click on "Add..." button
4) Choose "org.eclipse.scout.rt.ui.swing.browser.swt.fragment"
5) Go to Overview tab
6) Press synchronize
7) Press Launch application

Does this solve your problem?
I will open a bug for this later on.

Thanks for helping me.
Well it made the "placeholder for browserfield" go away but it doesn't display the URL yet..

I get this:

1) Which operating system are you using? Windows, Mac, Linux?
2) 32Bit or 64Bit?

The strange thing about this is, that when we start SWT, the Browser is working

Another question, did you run your application with the Rayo look and feel enabled? Can you try to use the plain Swing UI? Is it the same error message?
