GWT-EXT compatibility problem

[cyril.lakech]

Hi,

We use GWT-EXT 2.0.5 with GWT designer (2 days ago build).

We have many problems when we open existing GWT-EXT UI with GWT Designer...

So i try the GWT EXT Showcase samples to know if the compatibility between GWT Designer and GWT-EXT is OK

I just try the button and the borderLayout samples:
http://www.gwt-ext.com/demo/#buttons
http://www.gwt-ext.com/demo/#borderLayout

The samples use a Viewport so i try to remove this ligne with "RootPanel.get().add(panel);".

I get many errors when i open these samples with GWT Designer... What is the problem ?

Thanks a lot for your help...

Here is my errors:

[cyril.lakech]

The buttons sample (http://www.gwt-ext.com/demo/#buttons) works fine if i removed the listeners.

I think their is a problem with ButtonListenerAdapter:

Caused by: com.google.gwt.core.client.JavaScriptException: (TypeError): 'listener' a la valeur Null ou n'est pas un objet.
number: -2146823281
description: 'listener' a la valeur Null ou n'est pas un objet.

Ok i can remove my listeners from my UI.

Now i'm going to look to the bordellayout problem. (http://www.gwt-ext.com/demo/#borderLayout)

[Eric Clayberg]

GWT Designer will probably not work with any of their showcase examples as we don't support any of the GWT-Ext panel types yet.

If you want to use GWT-Ext, you should create new code using the widgets on the GWT-Ext palette.

[cyril.lakech]

Thanks for the answer!

So, i have to change my mind about using GWT Designer for the dev team.

We need to create a full GWT-EXT powered application with sexy widgets and layout. Basics GWT widgets are too simple and we can't use them.

Maybe in e few mounths we will try GWT Designer again... we are ready to buy licences only if GWT-EXT and/or EXT-GWT is fully supported.

I will keep an eye on the forum and the news, just in case i see a thread called "Latest build = GWT-EXT full support"

Regards,

[Eric Clayberg]

GWT Designer will already let you use almost all of the "sexy" GWT-Ext widgets, and the standard GWT layouts are generally good enough for just about anything.

[cyril.lakech]

Yes, i just have a discussion with a colleague, and we decided to try another way to use GWT Designer.

We will use native GWT Panel/Layout mixed with GWT EXT UI Components.

If you have a list with the supported Widget and the unsupported one, we are very interested ! We would know with part of GWT EXT we can use for sure, and the part we must wait before to use it. We would like to choose the Component when we design the screen (at conception phase).

By the way, we are going to buy only 1 licence at the end of the free trial, and we will wait for a while before buying more licences.

Thanks a lot for the responsiveness !

You would need look at the GWT-Ext palette within the product.
