How do I change the separator in the result of a multiselect

Hi,

The select2 plug-in returns multiple items separated by a comma. I need to change that to a colon to be compatible with the apex shuttle box item which was previously used for the page item.

I see in the code that the render function has l_token_separators gt_string := p_item.attribute_12, but that doesn’t seem to have a corresponding item in the Settings section of the page item.

Thanks in advance!
