DISPLAY and DELETE

PointsWell

I have a sequencing problem.

I have a VP which displays a form. The form is a child object of another BO that is is the LIRU. The form has a delete button on it. When the delete button is pressed it should:

Change a flag on the parent BO
Remove the child from the peer relationship in the parent BO
display a blank Layout where the form was

Here's the issue: if you try to delete a BO that is being displayed you get an error that the BO cannot be found. I normally get around this by interlacing the VP with the blank layout and then deleting. But I can't do that here because I only want a panel within a VP to go blank, so I thought DISPLAY LAYOUT with the blank layout and have the process to run in the same panel.

The DISPLAY LAYOUT therefore has to happen before the DELETE but because of how AIM handles the DISPLAY when it is not the last item on the rule list I am getting a popup window instead of the required panel going blank.

Any suggestions?

My current work around is to create a TrashCan BO with 2 attributes

TrashID
TrashObject

When I want to delete the object I will

Remove the object from the Parent BO
Create a TrashCan record, with the ID of the record and the name of the BO
Have the form update to display the Blank Layout
Use a timed process to run and delete the BO which will no longer be in context

I confess to not liking this work around as I don't like batch processes to clean up issues and it will create a whole chunk of overhead to ensure that the details don't accidentally turn up somewhere, though I suppose I can anonymise the TrashCan record by setting all the attributes to UNDEFINED.

EDIT

Fails. Because fields can only be either mandatory or not mandatory trying to set them to UNDEFINED triggers an error, even when setting by a process. There is no NO RULES NO VALIDATION option for setting attributes via processes.

Try,

put the ID into a non persistent BO (for EG NPBO.integernumber)
Do a REMOVE BO FROM Parent.children
FIND BO WHERE Bo.ID = NPBO.integernumber
DELETE BO
