I use ExtJS Classic 7.3.1.

Hi, tell me what to do, please I found a bug - https://fiddle.sencha.com/#view/editor&fiddle/3rlq

when restoring a state, if a column has a sorter and is located in another column, an error occurs.

at the same time, if the column is taken out separately (Type (OK SORTER)), then everything is restored perfectly.

actions:

  1. sort by column Type (OK SORTER);
  2. refresh the page - the restoration of the state should go fine, i.e. the sorting will be on the column from paragraph 1;
  3. sort by Day column (BUG SORTER)
  4. refresh the page - it will try to restore the state, but it will fall with an error
  5. clear the ext-tree panel state in localStorage

You have to add the sorter to the subgrid.

  1. Remove all sorters from your treepanel.

  2. Create a custom column-type for your sub-columns

  3. Create your own functionality for applyColumnState, getColumnState and sort

    Ext.define('MyApp.SubColumn', { extend: 'Ext.grid.column.Column', xtype: 'subcolumn',

     applyColumnState: function...,
 getColumnState:   function...,
 sort:             function...

    });

Now you can customize your column states as you like.

With a bit of tweaking you should be able to get it running.
