How to chain combo with viewModel stores

[[email protected]]

Hi,

i am trying chain comboboxes with references as sencha examples do in:
http://dev.sencha.com/extjs/5.0.0/ex...combo-chaining

When i add the filter config on second combo we recive the error:
Cannot read property 'getFilters' of undefined

A fiddle with the problem:

¿Could the store type generate the problem?

Hi

One solution is to move the filters config to the store.
This examples uses a selection binding instead of a reference:
https://fiddle.sencha.com/#fiddle/98e

Or you add the filters config to the combobox (same as the kitchensink example).
But it has to be inside the bind object.

xtype: 'combo',
bind: {
  store: '{fooStore}',
  filters: {
     property: 'bar',
     value: '{selectedBar.value}'
   }
},

Bind filter was the solution.

Thanks a lot Ralph!

but doing so, the child combo get's filtered on every parent combo change, even if the user types characters (filters) and thus the returned value of the parent isn't a valid ID, but a string (typed) ...

is there a way to avoid supplementary (unnecessary) server callbacks (if child combo is remote filter) ?
