Hi,
Since version 2018.0.5 of the standard template, a problem is occurring when I have a lookup that uses the "Multiple" and "Use modal dialog for lookup" options together.
When I select more than one option in the filter, they are displayed in the filter session. However, when I submit the search and the data is displayed, in the field where I selected several options, only one appears.
I hope it can be solved soon.
