Protect Rule

vinsnash

I have two Yes/No attributes on a form that I want to protect when creating a new object. They are defined with an initial value of 'No'. Using the rule

If NSCPers is New Then

Protect NSCPers. NewID From All
Protect NSCPers.Reenroll From All

does not work. When either check box is accessed the check mark appears briefly then resets to 'No' only the first time. If the users clicks on the box again it sets to 'Yes' and can be saved that way.

Using the rule

If NSCPers is New Then

NSCPers.NewID = 'No'
NSCPers.Reenroll = 'No'

keeps the two attributes set to 'No' on save but the user can still click on the fields and the 'Yes' check mark will show. Messy, but it accomplishes the task.

There should be a way to disable the boxes such that they can't be visited at all when creating new.

The protection rule is only executed when an object is saved. If you want it to execute when the form is displayed but before it is saved, you have to go to the Advanced tab and mark the rule as "used during initialisation".

Alternatively, do not set the initial value to "No" - instead set it when the object is saved:

If NSCPers IS NEW Then
NSCPers.YesNoAttribute = 'No'

And then check for undefined in the protection rule:

If NSCPers.YsNoAttribute IS UNDEFINED Then
PROTECT ...

The rules with UNDEFINED are automatically used during initialisation.

After some experimentation and trial and error I have found that if I only specify two actions and with the rule set for initialization

If NSCPers Is New Then
Read Protect NSCPers.NewID From All
Read Protect NSCPers.Reenroll From All

the result is as expected. Both check boxes do not appear.

If I add a third action

If NSCPers Is New Then
Read Protect NSCPers.NewID From All
Read Protect NSCPers.Reenroll From All
NSCPers.MemberStatus = 'P'

both the check boxes appear on the "Create' form and are active. It doesn't matter if the action is added as number 1 or number 3.
