Hello everybody.
I tried to limit the length of the string in tagfield. As was written in the manual, you need to use 'maxLength' and 'enforceMaxLength'. But that did not work.
Thanks

Code:
Ext.application({
    name : 'Fiddle',


    launch : function() {
        var shows = Ext.create('Ext.data.Store', {
            fields: ['id','show'],
            data: [
                {id: 0, show: 'Short tag'},
                {id: 1, show: 'Short tag'},
                {id: 3, show: 'abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz'}
            ]
        });


        Ext.create('Ext.window.Window', {
            //renderTo: Ext.getBody(),
            title: 'Tagfield Test',
            height: 200,
            width: 500,
            layout: 'fit',
            items: [{
                xtype: 'tagfield',
                maxLength: '10',
                enforceMaxLength: true,
                fieldLabel: 'Pick a tag',
                store: shows,
                displayField: 'show',
                valueField: 'id',
                queryMode: 'local',
                filterPickList: true,
                minWidth: 300,
                maxWidth: 200,
                maxHeight: 10
            }]
        }).show();
    }
});
