MyEclipse: GWT Plugin

Post subject: GWT Plugin

Hi,

I've got something very weird happening using the Google plugin with
MyEclipse 9, but I am out of ideas as to what it could be. I've
developed and deployed Java websites to GAE, using older versions of
the Google plugin, but with the latest one, I seem unable to do
anything. I simply cannot click on the "sign in to Google" button, and
have anything happen. I click it, and zero, zilch, nada, nothing
happens at all. I can right-click it, and get prompted for "Icon only"
or "Sign out on exit", but cannot actually sign in.

It seems to be a problem with the internet connection to google!
I installed plain Eclipse 3.6 IDE incl. Google GWT Plugin there the logon Buttons works, when I log on, and start MyEclipse in parallel, I'm logged on to google to, so GAE deployment works fine?

reich,

Sorry that you are running into this issue.

Can you answer some more questions for me to be able to replicate the issue at my end ?

1) How did you install MyEclipse 9 ? Is it through All-In-One installer/Pulse/Archived Update site ?

2) Can you share your build id from Help > About MyEclipse Enterprise Workbench > Build Id ? Paste the build id here.

3) How did you install the GWT plugin and which version? Can you please check if the version of GWT is compatible with base Eclipse version 3.6.1 for MyEclipse 9 ?

4) Did you install any other third party plugins lately ?

5) Start the IDE with -clean, switch to a new workspace and check if the issue persists. If yes then check for related errors logged in the .log file which is located at <workspace dir>/.metadata/.log. Paste the entire error message here for me.

Let me know how this works for you.

David,

The issue no longer exists in MyEclipse version 10. The issue is fixed by Google in Eclipse 3.7 version. I recommend you install our latest release version 10 and check.

You can download MyEclipse 10 from this link :
http://myeclipseide.com/index.php?name=Recommend_Us&req=Download&version=ME

Alternatively you can use Pulse to install MyEclipse 10. Here is the FAQ: http://www.myeclipseide.com/PNphpBB2-viewtopic-t-25976.html

You do not have to uninstall MyEclipse 9. You can install ME 10 alongside version 9 or to a new location.

Let us know how it works for you.
