Thanks Matt for your advice. <div><br></div><div>Anyway I didn`t succeed it. As you comment, first I should create an array by using 'collect' method on combo's store. I got it by using an easy example of an arraystore (static) but in my example, with data provided by an web service, when I use collect method like this: </div>
<div><br></div><div><br></div><div><div>var combo1=new Ext.form.ComboBox({ </div><div><span class="Apple-tab-span" style="white-space:pre"> </span>fieldLabel:'Filtro Pais', </div><div><span class="Apple-tab-span" style="white-space:pre"> </span>name:'cmb-P', </div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>forceSelection: true, </div><div><span class="Apple-tab-span" style="white-space:pre"> </span>store: store2.collect('COUNTRY'), //store2 is my combo's store </div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>mode: 'local',<span class="Apple-tab-span" style="white-space: pre; "> </span></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>emptyText:'Select a country', </div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>triggerAction: 'all',</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>//allQuery: 'DISTINCT',</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>editable:false, </div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>displayField:'COUNTRY', </div><div><span class="Apple-tab-span" style="white-space:pre"> </span>valueField: 'COUNTRY'</div><div><span class="Apple-tab-span" style="white-space:pre"> </span><span class="Apple-tab-span" style="white-space: pre; "> </span>}); </div>
<div><br></div><div>Nothing is appeared. I think that store is not loaded, so nothing can happen but why I got it if collect is not used?</div><div><br></div><div>I can figure out what is happening.</div><div><br></div><div>

<div>You’re going to want to use an ArrayStore for that “COUNTRY” combo box, not
the feature store.</div>
<div>If you use the feature store and filter unique countries, you will also be
filtering the grid.</div>
<div>Provide the array returned by the ‘collect’ method (<a title="http://docs.sencha.com/ext-js/3-4/#!/api/Ext.data.Store-method-collect" href="http://docs.sencha.com/ext-js/3-4/#!/api/Ext.data.Store-method-collect" target="_blank">http://docs.sencha.com/ext-js/3-4/#!/api/Ext.data.Store-method-collect</a>)
on the feature store to the ArrayStore’s loadData function.</div>
<div>Put a listener on the combo box for the ‘select’ event that uses the
selected value to filter the feature store is you want to limit feature records
by that value.</div>
<div>If you are just looking to do linked combos, and not do any filtering or
only filter after the user has made a series selections from linked combos, then
you should have the ‘select’ listener for the first combo box ‘query’ (<a title="http://docs.sencha.com/ext-js/3-4/#!/api/Ext.data.Store-method-query" href="http://docs.sencha.com/ext-js/3-4/#!/api/Ext.data.Store-method-query" target="_blank">http://docs.sencha.com/ext-js/3-4/#!/api/Ext.data.Store-method-query</a>)
the feature store and either directly use the returned collection in the linked
child combo box(es) or further process the collection to unique values for a
simple array store backed combo box</div>
