How to restrict view existing items & allow add new items?

[anthonylau]

Hi all,

My scenario is:
Task1: Start workflow with an item
Task2: Only allow add/remove new items and view existing item

I have tried to override the action group with following config.

<property name="bpm:packageActionGroup">
   <default>add_package_item_actions</default>
</property>
‍‍‍‍‍

There is an add button in the form. The problem is user can remove existing item from the item selection dialog.

How can I allow user to add item but not removing existing item?


Thanks a lot,
Anthony

Hi there,

I don't know exactly if this will work but here is my opinion:

1) Create a form type that extends bpmackageActionGroup type, for example mf:customPackageActionGroup.
2) Use that custom type in the form task that you need to allow add/remove items, and the "original" bpmackageActionGroup type just show it with read-only attribute set to true.
3)In a script task or a service task, iterate over mf:customPackageActionGroup and inject the nodeRefs of the items added in the task  to the  bpmackageActionGroup.

I hope that idea works!

Best Regards
