The transition from ExtJS 4 to ExtJS 5: A comprehensive guide

We're in the process of transitioning a web application from ExtJS 4 to ExtJS 5.

Upon testing the index.html, we encountered an error message (displayed in the Firefox-FireBug-console):

NetworkError: 404 Not Found - http://localhost:8080/ext/build/examples/ux/grid/FiltersFeature.js?_dc=1414147197935

I've checked for the FiltersFeature.js file within the directory, but it seems to be missing.

As per the "Whats New in ExtJS 5.0" documentation, this particular file was so widely used that they decided to relocate it.

Could someone advise on how I can include this file or its functionality to resolve the error?

I attempted adding the following code snippet to my app.js file:

Ext.Loader.setPath('Ext.ux', './ext/build/examples/ux');
Ext.application({
    ...
    requires: [
        'Ext.ux.grid.FiltersFeature'
    ],
    ...
});

However, the error persists. It appears that I may need to reference an object now stored elsewhere.

My challenge lies in identifying this reference and correctly implementing it within Ext JS 5.

Answer №1

The link you provided contains the essential information:

  • The Ext.ux.grid.FiltersFeature (ftype: filters) has been removed.
  • A new plugin called Ext.grid.filters.Filters (ptype: gridfilters)
    has been introduced as an upgraded replacement.

You will need to manually update your grids to utilize the new plugin instead of the old feature.

Best of luck with the changes.
