Ext 3 to 4 Migration

[brian.moeskau]

In ExtJS 3.3.1 there is the 'unstyled' config option in the Ext.Panel class.
In ExtJS 4.0 beta 2 this option is missing.

This is a bug, and it will be addressed soon, thanks.

where is it currently possible to read more about implementing those Ext.grid.features ?

This will be covered in the migration guide. For your issue, you'll need to implement the rowbody feature in the 4.0 grid. There's an example of how to do this in the PreviewPlugin grid plugin, as seen in the paging grid example (grid/paging.html). The code to use the plugin looks like this:

        viewConfig: {
            id: 'gv',
            trackOver: false,
            plugins: [{
                ptype: 'preview',
                bodyField: 'excerpt',
                expanded: true,
                pluginId: 'preview'
            }]
        },

Is this migration guide / conversion file be ready soon? Or even a draft copy of it since I have been twiddling my thumbs for the last week waiting for it to arrive.

I have a heavily modified grid panel, grid view and selection model which I need to work in Ext JS 4. Alot of what I have done has changed the templates themselves, will this cause me alot of issues with the change?

Yes. The compatibility file is for the public methods. If you've modified the internals of the class then you've done so "at your own peril" as it were.

The structure of the grid has changed quite a bit since 3.x.

EXTJS 3.3 allowed a STRING value for width and height. i.e. width: '500'

Under EXTJS 4 they are not allowed.
"Warning, size detected as NaN on Element.addUnits."

The value must now always be an INT i.e. width: 500

Hi guys,

Now that 4.0 is available I'm just wondering on the status of the compatibility layer mentioned here: http://dev.sencha.com/deploy/ext-4.0...iew/index.html

This is an optional JavaScript file that can be referenced after Ext 4 is loaded that will provide the aliases and overrides necessary to make the vast majority of Ext 3 code run correctly under Ext 4 as-is.

NOTE: At the moment this compatibility layer is not yet available, but it will be prior to the final 4.0 release.

I tried searching the 4.0 release for a file which could be it, but don't see anything. Is this likely to be available soon?

Thanks,
Matt

PS: Congrats on getting 4.0 out

Wonderful job!
I'll also wait for the compatibility pack.

[brian.moeskau]

The compatibility files will be available within the next few days.

The final release will include the standard JSB as always.

I downloaded the final release today but didn't really see a .jsb file. Am I missing it? Is there a different direction that Ext is going with the build process now?

[BulletzBill]

Does the 4.0 final include the gray theme or does it only have the default blue theme? Also I noticed the 4.0 examples are not using the new "Neptune" theme, has that been dropped from the initial release?

Do you know when the Migration Guide will be coming out? We'd really like to upgrade, but need this guide to get us going.
