[PR5][FIXED-EXTJSIV-189] ComboBox Selection Issue

[PV-Patrick]

Is anyone experiencing issues with the ComboBox selection of items? I can't seem to duplicate or narrow down this issue and it seems to happen at random intervals. What happens is if you just keep selecting options it eventually "freezes" and I am unable to select options in the ComboBox anymore. Sometimes this happens at selection #2 and sometimes it's selection #22. It almost always happens after I resize the window in which the form with the combobox is contained.

Here is the combobox I am using:

                xtype            : 'combobox',
                fieldLabel        : 'Type',
                name            : 'type',
                typeAhead        : true,
                store    : new Ext.data.ArrayStore({
                    id        : 0,
                    fields    : ['value','option'],
                    data    : [['0','Option 1'],['1','Option 2'],['2','Option 3']]
                }),
                valueField        : 'value',
                displayField    : 'option',
                emptyText        : 'Select token type...',
                queryMode        : 'local',
                forceSelection    : true,
                allowBlank        : false

This is happening in both FF and Chrome and as I mentioned, I can't seem to find a solid pattern to duplicate the issue 100% of the time.

I have the same issue, but when using a JSON Reader:

{
  displayField  : 'name',
  fieldLabel    : 'Country',
  name          : 'country_id',
  store         : new Ext.data.Store({
    fields: [
      { name: 'id', type: 'int' },
      'name'
    ],
    
    proxy: {
      reader: {
        root: 'rows',
        totalProperty: 'count',
        type: 'json'
      },
      type: 'ajax',
      url : 'data/country'
    }
  }),
  triggerAction : 'all',
  typeAhead     : true,
  valueField    : 'id',
  xtype         : 'combo'
}

Every attempt to select an item from the list results in a failed selection but no error.

Very similar code, so won't repost but as of yet I've been unable to get selecting an item in a combobox to work. The trigger works fine, and I can see all the items in the store listed - but the click event on the item itself doesn't work.

This is currently happening to me with every combobox I have in my forms with PR5

Putting the data local to the config and switch the proxy type to 'memory' did not change the lack of selection response.

Hi,

I have the same problem, details is related in this post

[jlmorgan]

Seems to be anchored around:

Allows a selection:

queryMode: 'local'

Fails at selection:

queryMode: 'remote'

Difficult tracking down where queryMode and isLocalMode are causing this failure, but it's happening around that config option.

Looks like the problem is in SetValue() of ComboBox.js. I believe there should be a line:

delete me.inSetValue;

just after the model is selected (ie. after line 842).

[cram]

oops, make that after line 834. With context:

if (models.length) {
    selModel.select(models);
}
delete me.inSetValue;

Thanks cram, you were correct. The fix has been committed.
