There seems to be yet another problem with the latest Chrome plugin where it won't load in dev mode when the codesvr argument is pointing to your local ip address. Try switching the ip adress portion of the argument to either "127.0.0.1" or "localhost" in your browser. You might also have to add "-bindAddress 0.0.0.0" to you eclipse launch config.

This worked for me but I didn't dig any deeper to understand the problem more thoroughly. I also don't know how this will effect remote debugging. Perhaps someone else has better info.

On a side note, this latest plugin fixes the Chrome22/OSX issue that was plaguing everyone for the last several weeks. Unfortunately, it now introduces this new issue.

Started getting 'Could not load GWT DMP Plugin' yesterday when I start my app from Eclipse using Chrome.  Happening on both work and home computers.  From web searches, it looks like this has happened in the past, which seemed to indicate that in those cases a new plugin was deployed that had issues.  In those cases there was no clear fix except some people has success rolling back to an earlier version of the plugin.

I've tried reinstalling the latest plugin.  Didn't see any option for downloading previous versions from the app store.  Tried restarting Chrome, Eclipse, and rebooting the machine.

Has there been a recent update to the plugin?  Where can I get the previous one to roll back to?  Is there another update coming soon that will fix this?

My home set up is:
Windows XP SP 3
Eclipse Helios Service Release 2 build ID 20110218-0911
Chrome 22.0.1229.94 m
GWT Developer Plugin 1.0.11338

My work set up is similar but with Window 7

Not to mention Chrome loads an old version of my site that I can't seem to clear when I don't use the plugin...kinda left dead in the water here.

Tony, thanks for the reply.  I didn't have much luck using different ip addresses though.  Initially, the url generated for launching in dev mode was 127.0.0.1.  I tried changing it in the Chrome address bar to local host and the machine's URL.  I also added the "-bindAddress 0.0.0.0" to the eclipse configuration.  That changed the url generated for launching dev mode to my machine's url, but still no luck.

I'll keep playing with it.

Same here. Glad I'm not the only one.

I'm on Windows as well, using v22 of Chrome.

Bah!

Yes, we released a new version of the plugin on Friday. For some reason, upgrading to the new plugin loses your preferences for the hostnames that Dev Mode is allowed to connect to. So you'll have to add them again. Sorry about that!

If it's not connecting and the toolkit icon on the right side of URL bar is gray instead of red, click on the gray icon to pop up the dialog to add the hostname.

An alternate way to get to the same options page:

2. Find the entry for GWT Developer Plugin
3. Click on "Options".

Suppose the URL is: http://myhost.example.com:1234/something?gwt.codesvr=anotherhost.example.com:456

You need to add an entry to the list for "myhost.example.com" and "anotherhost.example.com" to allow this connection.

However, it's usually easier to visit the URL and click the grey icon to the right of the URL bar. If you use that dialog, it will automatically use the correct hostnames.

The Eclipse setup shouldn't matter. What error do you get in the browser when it doesn't work? Are there any messages in the Console?

Also, could you check chrome://plugins/ to make sure that there's an entry for "GWT Development-Mode Plugin"?

Hi Brian,

She and I are using Windows XP SP3, Eclipse 4.2 Juno, JDK 1.6 U32, Standard eclipse GWT Plugin version 2.4. The webserver and code server addresses are both 127.0.0.1 . We've set both localhost and 127.0.0.1 in the plugin options but it still doesn't work. Is there anything on the Eclipse side that needs to be set to be compatible with the Chrome extension?

Thanks

This workaround is also not working for me. I don't even see the toolkit icon in the statusbar. 

I'm using m2eclipse and everything worked fine out of the box until last week. 

Setup: Juno, m2eclipse, Chrome 24 dev (but also tried 22), Windows 7

Hello Brian,

until now I've never had an entry in my preferences for the hostnames because I always used localhost as code- and webserver.
(by the way... adding localhost to the list does not work either...)

A new version is now live in the Chrome store. The only difference is that the Windows version is statically linked.

I don't have a sufficient number of Windows machines available for testing, so I don't know how much this will help. However, it shouldn't make things worse.

In my testing, I can start the "Showcase" sample in dev mode and it seems to work, but if I leave the browser open for a while, the plugin will eventually crash.

I'm still seeing some crash reports but I'm not sure they're the same issue. Has the situation improved at all with yesterday's release?

I just figured this out: you can report the crash to me by visiting chrome://crashes and telling me the crash id (if it's listed there).

(There is a link on that page to file a bug, but that goes to Chromium and they won't know what to do with it.)
