Add to Picklist Dynamically
By default, a picklist field of type "Lookup", will display
all the values present in the lookup field. The deluge add item
task is used in on user input field action script and on
load form action script, to add an item to a picklist/radio button/checkbox/multiselect
lookup field. For example, in the SubmitFeedback form given below, each
issue submitted is assigned to a specific team member belonging to a specific
module. When a Modue is selected from the Module Name picklist,
only those team members belonging to the selected module will be listed
in the Assign To picklist. This is achieved using the <picklist
fieldname>:ui.add(value) Deluge syntax.
Syntax
|
<picklist fieldname>:ui.add(value);
|
where,
<picklist fieldname> is the name of the picklist field in the
current form.
<value> is the value to be added to the above picklist.
 Note: You cannot import a picklist field into another form. |

I'm dynamically adding elements to a multi-select picklist using a custom button on a stateless form. I had assumed that the ui.add function would append to the current picklist. However, there seems to be an implicit Clear executed before the For Each loop. Is there any way to keep the entries in the picklist from a previous On Click when adding new ones?
