setting a combobox to an item from an attached valuelist

How do I set a combobox to item 3 (can be anything) of an attached valuelist.
This doesn’t work

var myArray = application.getValueListItems(‘FormsList’)

forms.controls.elements.global_Form_list = myArray[1];

returns an error about locked scope.

I tried setting the field to be editable to no avail…

Ideas ?

TIA

With this function you do not get an Array back – you get back a dataset type. So:

var dataset = application.getValueListItems('FormsList');
fieldName = dataset.getValue(3,1);

To set a combo box field to the second and third items:

var dataset = application.getValueListItems('FormsList');
fieldName = dataset.getValue(2,1) + '\n' + dataset.getValue(3,1);

doing as stated above gives me:

Error

Can’t put in a locked scope, name: global_Form_list, value: Klanten

:cry:

In your code, the left side of this assignment is wrong:

Odysseus:
forms.controls.elements.global_Form_list = myArray[1];

You cannot assign a value to an element. You can only assign a value to properties of elements. That being said, the function:

elements.name_first.replaceSelectedText(myArray[1]);

behaves outside of this rule of thumb.

The left side of an assignment needs to be a variable or a field name:

 var x = myArray[1]
fieldNameX = myArray[1]

Which gets us back to this:

fieldName = dataset.getValue(3,1);

for this example.
