问题 I´ve spent a couple of days dealing with an issue about grids' vertical scroll. Scrolls just stop working under some unknown conditions, I mean, it is not deterministic I think.

问题 How to close the list of a Tagfield in Ext.js 6.0.2 by clicking on its label in Internet Explorer 11? Look into the Fiddle to test it. https://fiddle.sencha.com/#fiddle/1h9n 回答1: First, you need to understand what's going on better.

问题 I have 2 comboboxes. The first selects a category, the second selects the sub category. Both categories are stored in one store with fields: id, parentId, label. Filtering the store isn't working since both comboboxes are bound to the same store. How can I link the comboboxes? How can I filter the list of the second combobox? 回答1: Instead of referring to the same store use Ext.create() to create a new instance of the same store for the second combo box.

问题 I have a combobox on a form where I need to reset its store along with the 'displayField' and 'valueField' configs. Resetting the store via cmb.bindStore(newStore) works great. Setting cmb.displayField = 'newfieldname'; also works great. However, cmb.valueField = 'newValField'; does not work.
