rally - noEntryText attribute for ComboBoxes won't apply for Custom Fields? -

i'm working comboboxes , filters implement option select instances of desired field. said, know use noentrytext attribute set defaults "--no entry--" "all". however, changes not seem apply when use on custom fields provided web services api (those fields "c_" before them).

strangely enough though, convention works other fields use not have "c_" before them. known defect custom fields or there workaround issue?

i filed defect replacing noentrytext custom value works rallyfieldvaluecombobox standard fields, not custom fields. if rallyfieldvaluecombobox uses standard field, e.g. environment, no entry can replaced successfully:

here js file:

ext.define('customapp', {     extend: 'rally.app.app',     componentcls: 'app',     launch: function() {         this.add({             xtype: 'rallyfieldvaluecombobox',             itemid: 'abox',             fieldlabel: 'filter filed:',             model: 'defect',             //field: 'c_custombox',             field: 'environment',             noentrytext: 'all',             usenullfornoentryvalue: true,             allownoentry: true,             listeners: {                 select: this._onselect,                 ready: this._onload,                 scope:             }         });     },     _onload: function() {         this.add({             xtype: 'rallygrid',             columncfgs: [                 'formattedid',                 'name',                 //'c_custombox'                 'environment'             ],             context: this.getcontext(),             storeconfig: {                 model: 'defect',                 filters: [this._getstatefilter()]             },             width: 500         });     },     _getstatefilter: function() {         if (!this.down('#abox').getvalue()) {              return 1;         }         else{             return {                 //property: 'c_custombox',                 property: 'environment',                 operator: '=',                 value: this.down('#abox').getvalue()             };         }     },     _onselect: function() {         var grid = this.down('rallygrid'),             store = grid.getstore();          store.clearfilter(true);         store.filter(this._getstatefilter());     } }); 

if same rallyfieldvaluecombobox uses custom field, no entry string cannot replaced:

in both cases functionality of replacing filtering behavior works fine.
