Business Rule Condition not working

[m_m]

The following condition works when the assignment group value selected from the assignment_group drop down list is 'Maintenace':

current.assignment_group.changes() && current.assignment_group.getDisplayValue() == 'Maintenance'

However, this condition does not work when the same 'Maintenance' value is autopopulated via an assignment rule

Further, this condition was used in replacement for my original condition (!current.assignment_group.nil() && current.assignment_group.changesTo(gs.getProperty('table.external_group'))) because I couldnt get that to work. The issue appears to be the use of the function changesTo().

Can anyone help please?

How about this?

current.assignment_group.changes() && current.assignment_group.name == 'Maintenance'

Try using the Filter Condition of the Business Rule form.

Then I believe the debugging tools may help you in order to check what is not working

Thank you both for your replies.

From what I can see now I have this working. When I posed the question, the BR was a "Before" Business rule. I have now used an async BR rule for invoking my Web Service and I am using var response = s.executeAsync();

This has allowed me to go as far as using the following code in my Condition:

!current.assignment_group.nil() && current.assignment_group.changes() && current.assignment_group.getDisplayValue() == gs.getProperty('table.maintenance.external_group')

This is working fine for new records and existing records. I just have to reload the page to see the update in work_notes and the value entered in the correlation_id field.

I just need to work out how to correctly use changesTo() to replace current.assignment_group.changes() && current.assignment_group.getDisplayValue(). Using changesTo(gs.getProperty('table.maintenance.external_group')) doesn't want to play ball.

changesTo won't work with async rule.
