GWT internal error No or multiple broswer support plugins

[doubtintom]

I'm really excited about this product and have two clients waiting with projects!

I have Designer 1.7.1 latest build working great with Swing and SWT on my Suse 10.1/x86_64 box. But the GWT Designer tutorial example, as soon as I click the designer tab, shows "Unknown Window Type" and gives the following trace in .metadata/.log file. Any clues or suggestions?

The GWT hosted web browser does not work in 64-bit Linux. See...

http://code.google.com/p/google-web-too ... ail?id=134

A work around is suggest there.

Thanks! That helped some. I can run the GWT hosted web browser as long as I use a x586 java and have the path to mozilla-1.7.12 in the LD_LIBRARY_PATH. I can run the shell versions of all of the examples now.

However...the Designer Design tab in the Eclipse browser still does not work.

I have my Eclipse GWT Designer tutorial project set to the x586 JRE. The LD_LIBRARY_PATH is set to mozilla-1.7.12 in my .bashrc, but when I click on the "Design" tab, I get "Unknown Window Type" and the design, property and palette areas are all blank. Looks like this: http://meddevsqa.com/designer-problem.png

Notworthy, though, is that the first two errors in the .log file have vanished, i.e.:
!MESSAGE Designer internal error [6.3.1.20070601074650]: No or multiple broswer support plugins.
and
!MESSAGE Designer internal error [6.3.1.20070601074650]: java.lang.reflect.InvocationTargetException

That is encouraging progress. Only the
!MESSAGE Designer internal error [6.3.1.20070601074650]: java.lang.NullPointerException
remains, exactly as before.

Does any of this data suggest a next step?

Thanks,
Tom Miller

Does any of this data suggest a next step?

It could just be a simple configuration problem of some sort at this point. We don't have any 64 bit Linux machines to know for sure. I would suggest reviewing the following FAQ entries to see if anything helps...

What should I do if Designer does not work after installation?

What should I do if I encounter "Unknown Window Type (Parsing Error)"?

What should I do if I encounter an UnsatisfiedLinkError:DOMImplIE6.init() exception using GWT Designer?

[doubtintom]

Thanks Eric

I've come much farther along, still hitting problems.

Here's what I did:
1. downloaded & installed a 32 bit JDK

2. put this in my .bashrc

Code: Select all

export LD_LIBRARY_PATH=/home/tmiller/bin/gwt-linux-1.3.3/mozilla-1.7.12:/lib64

export PATH=/usr/lib/jvm/jre-1.5.0-sun/bin:$PATH
export JAVA_HOME=/usr/lib/jvm/jre-1.5.0-sun


3. installed a 32 bit copy of Eclipse

4. Used Gnome, GWT Designer just doesn't work properly with KDE

So, now the "Unknown Window Type" problem is gone, the "Design" tab works, and I'm able to do drag and drop widgets into the design area. This is great!

5. However, when I attempted to use the CSS Style Selection dialog by clicking on the ellipsis in the "styleName" row in the properties window, I got
org.eclipse.swt.SWTError: No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]

So, after a bit of googling and adding:
export MOZILLA_FIVE_HOME=/usr/lib/firefox
to my .bashrc, the CSS Style Selection dialog works!

6. On to right clicking the "Sign In" button to add an event handler. As soon as I select the "onClick" handler, the following is added to the workspace/.metadata/.log file. Eclipse pops a large message box containing the same.
!ENTRY com.swtdesigner 1 1 2007-06-04 07:37:00.291

So that is as far as I got, which is a long way, and encouraging. Can you give me any suggestions for the next step?

Turn off diagnostic mode ("Designer > General > Enable diagnostic checking" pref). You shouldn't turn that on unless we ask you to for some reason.

http://download.instantiations.com/Desi ... neral.html

"Enable diagnostic checking

This preference controls whether diagnostic checking is turned on. Diagnostic checking traps certain types of code generation errors. Diagnostic mode is intended to flag differences between the source that exists and the source as recreated by the Eclipse parser. Normally, the two will match exactly, but syntactical differences or problems in the source (even minor ones) will cause a diagnostic failure (this is intentional). In general, you should not turn this option on unless asked to for some reason by Instantiations technical support."
