Google Web Toolkit (GWT) + Google App Engine (GAE) + Detached Data Persistence

I would like to develop a web-app requiring data persistence using GWT and GAE. As I understand it, my only (or at least by far the most convenient) option for data persistence is GAE's Datastore, using JDO or JPA annotated objects. I would also like to be able to send my objects back and forth client-server using GWT Remote Procedure Ca...

Has anyone used "GWT Designer"?

Haven't seen anything about it here but it seems to solve one of the problems with GWT - the fact that you have to write Java code to generate your GUI. Instead this software allows you to design the GUI using drag-and-drop tools - a WYSIWYG interface. I'm not trying to sell the product, by the way. I just want to know whether it wor...

GWT JavaScriptObject reading "delete" property

I have the following native method in a extended JavaScriptObject class: public final native boolean getDelete() /*-{ return this.delete; }-*/; but this apparently doesn't work as "delete" is an javascript operator. How can I read this property correctly. The thrown exception is: com.google.gwt.dev.js.JsParserException: missing n...

GWT upgrade from 1.5 to 1.6

Has anyone upgraded an app from GWT 1.5 to GWT 1.6? I'd like to hear if you had a strategy that you liked for this, or if you even needed a strategy. Obviously, I can read the upgrade doc. Just wondering if someone's done the upgrade and hit any gotchas. ...

Has Jquery/MooTools/Prototype eliminated the need for GWT?

I don't hear much about GWT any more. When it first came out, it seemed to be all the rave in certain RIA circles. But lately my impression is that GWT has suffered a dip in popularity because solutions like Jquery/MooTools/Prototype offer a much easier way of solving the same problem. Is this accurate or does GWT solve a different ty...

Paging a GWT-EXT datagrid with GWT-RPC ?

I need to display data coming from a GWT-RPC service in a paginated datagrid. The gwt-ext showcase does not provide an example combining gwt-rpc calls and datagrids. That is too bad because the original javascript Ext grid components offer paging and remote sorting. How to take advantage of these features with GWT ? ...

No response in Eclipse: File ->Import->Existing Projects into Workspace

I'm trying to import one of the GWT samples into Eclipse by following the instructions below. But when I browse to the directory containing the "Hello" sample and uncheck "Copy projects into workspace", the Finish button is grayed out, preventing me from completing the import. Any ideas why? -- Option A: Import your project into Ecli...

How much support does GWT have for Java layout managers?

This seems to be a question where the answer is implicit, hence I can't find anything explicit. Does Google Web Toolkit only support custom layout managers, or a sub-set of the Java layout managers? For example, is it possible to take a Java Swing application using GroupLayout and get it to work with GWT? ...

GWT: FlexTable vs Table

Under what circumstance I should use FlexTable instead of HTMLTable? ...

Is it possible to separate totally the HTML/CSS layout from the GWT logic?

I'd like to allow our web developers to continue to work in pure HTML and to let developers to write GWT Java-only code to write the rest of the business logic. Is it even possible? Have anyone tried to work with the web developers in the GWT environment? How do you incorporate the web developers into the GWT development process? ...

Why might gwt be getting more popular?

I've noticed a dramatic increase in GWT popularity during the past 6 months. More evidence can be seen here: http://www.indeed.com/jobtrends?q=gwt&l= Can someone explain the cause? ...

Importing Groovy classes in a GWT module in Intellij

Basically I can't even import Groovy classes in a regular GWT EntryPoint: import com.google.gwt.core.client.EntryPoint; // OK import groovy.lang.Binding; // NOT OK import groovy.util.GroovyScriptEngine; // NOT OK Intellij 8.0's inspector keeps telling me this: Class 'groovy.lang.Binding' is not present in JRE Emulation Library so it...

How can I build a GWT Loading Dialog?

I have a page with a mix of HTML and GWT components. I'd like to not make the content viewable to the user until the content has completely loading (perhaps showing a simple loading dialog during the process). What is the easiest way of achieving this? ...

Why are there so few open source GWT apps?

Something I have found strange since I started working on GWT is how few open source projects there are in this technology. Initially I was surprised to discover this mainly because GWT itself is open source. But after puzzling over this, my suspicion is that it is mainly used for internal projects by large corporations who already use...

GWT Incubator: single row in PagingScrollTable does not have proper height in IE7

I'm using the PagingScrollTable from GWT Incubator version 1.5-Dec_28, along with GWT 1.5.3. When I have only a single row in the table, the table height shrinks such that the row is no longer visible. If I add more rows, everything is properly sized. It seems as if maybe the height of the horizontal scrollbar is not being taken int...

Adding a GWT tab from a different tab

I want to add a tab to a certain tab bar from inside the content area. The content area is dynamic, and as such, is located in a different class file. The only way I know of to get the current state of the tab bar (not create a new tab bar object) is to create a static method and variable to access the object. However I'm having probl...

Google Web Toolkit: RichTextArea installation for PHP application

Google Web Toolkit features gwt-RichTextArea, a simple but effective WYSIWYG editor. Now I would like to use this editor in my PHP application but don't know how to implement it. I'm not sure but it seems it's only possible to implement when you're using JAVA. Tell me I'm wrong! ...

GWT 1.6 project war layout- mixing source code & compiler-generated artifacts?

Having just wrapped up a GWT-1.5 based project, I'm taking a look at what we'll have to do to migrate to 1.6. I'm very surprised to see that GWT seems to want to write its compiled output to the war directory, where you would normally have items under source control. What's the reason behind this? Did Google really think this was a go...

gwt socket connections

hi, I am trying to write an application that uses java.net.Socket. I have also written an app in Java using GWT to display the contents from an ArrayList. However, I now need to populate that ArrayList via a socket connection. Apparently Google Web Toolkit does not support socket connections. Can anyone please give me a workaround f...

I am writing an application using GWT on Windows that needs to do some network calls. I know that if these aren't to the same machine I'm developing on I need to setup a proxy, right?
