[paddykool]

Hi all,
I'm trying to use java script to select an item in a JSF comboBox (which is non-editible) but i can't get it working!!!

Below is the HTML that renders the control but i cannot find a way of clicking the combo button and then selecting an item using javascript

Can anyone help me please!! I'm going mad!!!!!

Yeah, was searching for it too and found nothing...
But exploring rendered HTML we can see that its not actually <select> but set of input controls.
Value is displayed in control $richFacesID+comboboxField (in your case - exceptionSearchOptionForm3:uehIdConditioncomboboxField)
On submit value is taken from hidden $richFacesID+comboboxValue (in your case - exceptionSearchOptionForm3:uehIdConditioncomboboxValue)

So to properly select value you should set both fields by js:
create js function:

function setComboBoxValue(control, value) {
    document.getElementById(control.id + 'comboboxField').value = value;
    document.getElementById(control.id + 'comboboxValue').value = value;
}

and then use it in your jsp:

setComboBoxValue(#{rich:element('exceptionSearchOptionForm3:uehIdCondition')}

rich:element(...) is needed if your control is deeper in DOM and you don't know its full path.

Hope it will help.
