smartGWT and Eclipse with WindowBuilder

I am using eclipse Helios with SmartGWT. If I start the WindowBuilder to design a GUI I always get this error message:

WindowBuilder supports only SmartGWT versions 2.2, 2.3. But 2.4 found.

I tried to use SmartGWT Version 2.2 by removing the 2.4 jars and adding the 2.2 jars.

However the message remained the same. If I use the开发者_开发知识库 GWT Designer it works, but I do not get the SmartGWT controls, but just he usual ones fropm GWT. I know that I had it working with SmartGWT 2.4 some ancient time but I have no idea what's wrong now... Does anybody have an idea ? It would already help I could get the smartgwt controls to the WT designer but I have no idea on how to do that...

Thanks very much

You have to follow the instructions here.

To summarize:

1. create a new java project with the gwt designer class found here

2. add the version numbers to the VALID_VERSIONS and VALID_VERSIONS_STRINGS in the code (eg, "3.0", "3.1", "4.0")

3. you'll have to add the following JAR's from your Indigo plugins folder:

   com.google.gdt.eclipse.designer.SmartGWT_2.6.0.r37x201206111253.jar com.google.gdt.eclipse.designer_3.1.2.r37x201303061530.jar org.eclipse.wb.core_1.5.0.r37x201206111201.jar org.eclipse.jdt.core_3.7.3.v20120119-1537.jar org.apache.commons.lang_2.4.0.v201005080502.jar

4. close eclipse

5. open com.google.gdt.eclipse.designer.SmartGWT_2.6.0.r37x201206111253.jar with 7Zip or something and replace the class files, which will be under your project bin folder

This seems to be working well with SmartGWT 4.0 also. Unfortunately we're still stuck with using Indigo with WindowBuilder. Juno might work for simple GWT, but I don't remember. Kepler isn't working at all.
