extjs3 - Not able to set value for Ext.ux.form.MultiSelect in ExtJs 3.4 -

-

i using extjs 3.4.

when set value ext.ux.form.multiselect, getting error.

"uncaught typeerror: cannot read property 'clearselections' of undefined in multiselect.js:245".

if have clear selected values in "ext.ux.form.multiselect" before setting selected values, how can that.

please give suggestions this.

if mean this component, in setvalue method there call this.view.clearselections(), , causes issues. view created in onrender method. combo not rendered when call setvalue.

i see 3 solutions:

  1. ensure combo rendered when call setvalue
  2. check combo rendered; call setvalue when is, assign value when isn't
  3. override multiselect , fix it
