Attribute Rule Calculation

[klewis47]

Hi, 

I'm trying to make an immediate calculation rule for an attribute table that is associated to the polygon feature. I have the field selected, the expression worked when checked it, and I have the triggers insert and update selected. But when select a polygon and view my table the field value return null. Does anyone know how to fix this, or what I'm doing wrong?

Once selected, did you make a change (update) to the data so that the rule fires?

The rule will only execute if you add a new feature or update an existing one. Make a change to one of the features or add a new feature to see if the rule executes then you can copy the expression and use the calculate field option in the attribute table to update all of the remaining records in the table rather than editing them all to trigger the rule.

I'm having a similar issue, set up a calculation rule, verified the expression, selected insert as trigger, saved it and then created a new feature. The field in the new feature that I applied the attribute rule to still remains "Null". Is there a lag maybe?

For anyone interested, I am having success with this attribute rule now, after selecting both the "insert" AND "update" triggers.
