gwt Designer problem

[Eric Clayberg]

Open the class using the Designer Editor rather than Java Editor (which is what it sounds like you are using).

[Eric Clayberg]

No idea. A test case and your Eclipse ".log" file would be helpful.

I am also nit sure what the 3rd "it" is in your description.

[Eric Clayberg]

3rd time I refresh my hosted mode..

Sounds like a good issue for Google's GWT forum.

it is the subject of java but may be helpfull,
If I write this -> variable = new String[100];
do I have to write anythink like free(); delete(); , etc..
in order to free my memory?

No.

[Eric Clayberg]

What exact version/build for Eclipse are you using?

Have you tried increasing the amount of memory assigned to Eclipse.

If you are having a problem launching Google's KitchenSink example, you should post a description of yoru problem in Google's GWT forum.

[ERROR] Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M ...)

hi,
if you are running into memory issues when running application from within Eclipse (e.g. from within GWTD project using Run as GWT Application) incrase VM option for memory (-Xmx####). Just open run configuration and switch to Arguments section,

regards,
Peter

The Designer FAQ offers suggestions on how to increase the memory used by Eclipse.

Also, if you are using any version of Eclipse 3.3.x prior to 3.3.2, you should immediately upgrade to 3.3.2 to avoid known memory usage issues.
