Default Combobox value not selected

Hi,

I have been trying to set a combobox value by default when the combox renders on the page.

before that i am loading data in the combobox store.

combo.store.loadData(data);

combo.setValue(value) // value is a code value from the store only

In combox configuration i have selected queryMode : local.

I am not sure why combobox is not getting rendered with the value i am specifying, data is loading properly.

Please help !!

Thanks in advance
