multi-column combobox via JSON?

[kevin price]

Hi. I have a form that is loading purely via JSON. like so:

// grab raw JSON layout from php file:
FormJSON=Ext.decode(GetFormJSON('myformjson.php?s='+seqno));

// now create FormPanel to insert into window...
var frm=new Ext.FormPanel(FormJSON);

The form popups up great with comboboxes etc but what i need is to make my comboboxes multi-column. I can specify my single column comboboxes no problem via:

{
xtype:'combo',
triggerAction:'all',
fieldLabel: 'Employee',
store:'["John","Sue","Frank"]',
name: 'employee',
value:'',
},

I've tried store: '[{"1","John"},{"2","Sue"},{"3","Frank"}]' but that doesn't work either. What is the format?

Thanks for any help!
Kevin.

The syntax for a static store of a combobox with a displayField/valueField config is:

[["1","John"],["2","Sue"],["3","Frank"]]

But I don't think this is what you are asking...

Thanks Condor.

Well, yes, that is what i'm asking. I just tried it and it it worked!

Sorry to lead this along but where is that going to show up when it posts to the server when I save the record, only the name (ie Frank) shows up not the id.

Condor,

Actually let me clarify, but you have solved 1/2 my problem...

I can now get the display correct with the names of the employees, I didn't know about the displayField/valueField thing. How would I specify that the 1st element is the value and the 2nd is the Display and to post the value when it does the AJAX save later? I don't name the columns so I can't give them a name. On post I only get the displayValue (Frank).

Regards,
Kevin.

SOLVED!

OK for the benefit of others, here is the solution:

{
xtype:'combo',
triggerAction:'all',
fieldLabel: 'Employee',
store:'[["1","John"],["2","Sue"],["3","Frank"]]',
name: 'employee',
value:'',
hiddenName: 'employee'
},

So i added "hiddenName", that makes it post the value not the text on the post.

Thanks for everyone's help, especially Condor.

Correct, the only thing you can leave out is the name:'employee' (it's either name or hiddenName, but not both).
