ExtJS 4 Combobox Vertical Scrollbar Is Gone!

cmbCombobox.getStore().loadData(arrayData);

I use this code to load my arrayData into Combobox. getStore() method does not exists anymore in ExtJs 4. So i use this code开发者_开发问答 to load data:

cmbProvince.store.loadData(provinceData); 

But vertical scrollbar is gone when i load data by this code. Has anyone realized this problem?

I ran into the same thing today. You should be able to do:

cmbProvince.createPicker() 

to force it to "redraw" the dropdown, which added the scrollbar back.
