    <p>I have to fill values in the right multiselect box in an itemselector. <strong>First i need to keep it blank and then on selection of an item in the combo box above it, i have to fill values accordingly</strong>. I have tried this and its crashing at the moment and nothing seems wrong. Here is the code snippet:</p> <pre><code>var userList = GetUserList(); var aoiList = GetAOIList(); var userAOIs = ""; var selectedUser=""; var userStore = new Ext.data.ArrayStore({ fields: ['user'], data: userList }); var aoiStore = new Ext.data.ArrayStore({ fields: ['aoiList'], data: aoiList }); var userAOIStore = new Ext.data.ArrayStore({ fields: ['userAOIs'], data: userAOIs }); var aafp = new Ext.FormPanel({ width : 350, frame : true, autoHeight : true, bodyStyle : 'padding: 2px 5px 0 2px;', labelWidth : 100, defaults : { anchor : '95%', allowBlank : false, msgTarget : 'under' }, items : [ { xtype : 'combo', fieldLabel : 'Choose User', emptyText: "Select User...", id : 'userId', name : 'user', multiSelect: false, store: userStore, displayField: 'user', mode: 'local', editable: false, typeAhead: true, triggerAction: 'all', listeners:{select:{fn:function(combo, value) { selectedUser = value.get('user'); userAOIs = myAOIs(selectedUser); userAOIStore = new Ext.data.ArrayStore({ fields: ['userAOIs'], data: userAOIs}); aafp.getForm().findField("itemselector").reset(); }} }, value : selectedUser },{ xtype: 'itemselector', name: 'itemselector', fieldLabel: 'AOISelector', imagePath: 'ext-3.4.0/examples/ux/images/', drawUpIcon:false, drawDownIcon:false, drawTopIcon:false, drawBotIcon:false, multiselects: [{ width: 250, height: 200, store: aoiStore, displayField: 'aoiList' },{ width: 250, height: 200, store: userAOIStore, displayField: 'userAOIs', valueField: 'userAOIs' }] }] </code></pre> <p>Initially i doubted the "aafp.getForm().findField("itemselector").reset()" call and thought that there might be some other function to dynamically reload the elements in the form, instead of reset which might be used to reset/erase the data in the fields but reset is reloading the contents. Please provide your inputs how this could be achieved?</p> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
