[brian.moeskau]

This thread is not for general Ext 4 bugs! It is for collecting Ext 3 to 4 migration discussion and issues in one place, including:

• Issues in the Ext 4 Overview Guide
• Issues in the Ext 3 to 4 Migration Guide
• Issues or missing overrides in the Ext 3 compatibility file
• Discussion about migrating specific code from 3 to 4

Migration Resources:

• 3 to 4 Migration blog post
• Download the Migration Pack under "Related Downloads" (includes guides, compat layer and demo application) - Updated May 27, 2011
• Ext 3 to 4 migration screencasts: Part 1 | Part 2

If you find anything while migrating that is not covered in any of the above, please post it here.

Can we expect a .jsb2 file or something similar in future releases of Ext 4? I looked in the first public release but couldn't find one. It seems this is particularly important for users of Spket because it wants to parse the .jsb2 file to discover candidates to participate in code completion. I've found Spket to be great for Ext 2-3, but please let us know if .jsb2 is no longer included because I might have to find a different editor or craft my own .jsb file...

This may not be the correct forum, but I second firefoxSafaris request.
If there is any other way to make Spket code completion work, or there is an easy way to make the jsb-file myself, I would appreciate any feedback.

I saw no adapters included in ext-4.0-pr1 like had been in 2 and 3. Could we get an official word on whether these will be included in the final release? If not, are there any anticipated issues with, for example, jquery and ext-js on the same page?

[brian.moeskau]

The final release will include the standard JSB as always.

Adapters are no longer supported, as mentioned in the overview guide. Any other libraries should be perfectly usable alongside Ext, and that will work even better now that Ext no longer modifies base JS prototypes.

Excellent. Good news - thanks for the prompt response.

Just out of curiosity before the jsb file is available, does anyone at Ext use Spket and if so does it work ok with 4?

[brian.moeskau]

AFAIK no one on the Ext side uses Spket actively, so not sure. However, since it just uses the JSB to generate it's code hints I would think it will work fine. I'm sure the Spket author will ultimately have to verify that.

I had no idea about JSB2 file until now... I looked into Spket since I use eclipse but it looks like it hasn't been updated since 2009. Is there a recommended plugin for eclipse that use JSB2 file?

I'm also interested in this

[sg707]

I tried to use Spket and didn't seem to work... ah well... For now, I'm using Aptana w/ ExtJS plugin provided by the community... it's fairly good but it's missing many API. It does not use jsb2 file for that though....

Can someone please respond?? If I can make JavaScript coding less painful, you'll be my hero of the day.
