DevMode woe

[Shawn Brown]

Can’t get DevMode to work.

Think it’s related to my app.gwt.xml using:

<module rename-to=‘app’>

Trying my page give me:

Error:Couldn’t load app from Super Dev Mode server at http://127.0.0.1:9876.

Am seeing (in Chrome brower dev console)

app.nocache.js:54 GET http://127.0.0.1:9876/recompile-requester/app net::ERR_FAILEDinjectScriptTag @ app.nocache.js:54

I think the codeserver is fine:

Super Dev Mode starting up

…

Initializing App Engine server

…

The code server is ready at http://127.0.0.1:9876/

I can view my data in the admin console fine

http://127.0.0.1:8888/_ah/admin/ <—- works great

Hints? Tips? Suggestions?

And can you access http://127.0.0.1:9876/ ?

 

[Shawn Brown]

Thanks for the quick response.

Yes and I get:

GWT Code Server

1. Drag these two bookmarklets to your browser's bookmark bar:
   Dev Mode On Dev Mode Off
2. Visit a web page that uses one of these modules:
   • app
3. Click "Dev Mode On" to start development mode.

So I did 1, but 2 gives me an error:

app (GWT Code Server)

This module hasn't been compiled yet.

Output Files

(From the last successful compile.)

• blank.html
• app.nocache.js
• app.nocache.js
• reset.css

Recompiling (from Eclipse GWT Compile Project) and trying again does nothing.  Restarting the server and trying again gives the same result.

 Sorry that was...

• app.recompile.nocache.js

 Setting (in eclipse) the GWT code server port and the Appengine built-in server both to automatically select an unused port (ended up 58777) and accessing it at

http://127.0.0.1:58777/MyApp.jsp

gets me a response of:

Compiling app

There aren’t any process open on my computer though using any significant amount CPU. 

So checking Chrome Dev Mode gives a error with a link

http://127.0.0.1:59040/recompile/app?gxt.device=desktop&gxt.user.agent=chrome&locale=en&user.agent=safari&user.agent.os=mac&_callback=__gwt_sdm_globals.callbacks.c1472993865970

Trying that link in a new tab shows this in my Eclipse server 

GET /recompile/ap

   Job com.k.app.MyApp_1_1

      starting job: com.k.app.MyApp_1_1

      binding: gxt.device=desktop

      binding: gxt.user.agent=chrome

      binding: locale=en

      binding: user.agent=safari

      binding: user.agent.os=mac

      skipped compile because no input files have changed

      0.410s total — Compile completed

Maybe the underlying confusion is that I am using an offline cache and it loads from that… 

Document was loaded from Application Cache with manifest http://127.0.0.1:59047/offline.manifest

Then gives me fluencybuildergae.nocache.js:54 GET http://127.0.0.1:59040/recompile-requester/fluencybuildergae net::ERR_FAILED

Still why the need for a recompile… nothing has changed.

Should I just give up on superdevmode until 2.8?  Will it have changed?  This is beyond my abiility to understand what to do…

No (not in a way that'd change anything to your problem)

Disable your application cache? 

[Shawn Brown]

Duh?!?!

Took my manifest=“offline.manifest” out of the html tag and it seems to be working fine….

Is there a way to get it to execute code modification in the debugger?  I found my source and adding a logging statement but can’t save the file so it doesn’t execute.  Is there a good book on this … is any chrome debugging book ok?

You can either use Chrome workspaces (https://developers.google.com/web/tools/setup/setup-workflow) or remote-debug from your IDE and have it handle the Source Maps (SDBG in Eclipse for instance: https://sdbg.github.io) 

[Shawn Brown]

Thanks.

SuperDevMode working

debugging with SDBG

upgraded to 2.8b2

Selenium testing works better this way!
