2699333 - onChange UI Rule


Need to hide fields based on onChange UI rule. However, this is not working.

*Note: This applies to all MDF Objects. For this KBA, we will use Position Object.

Position object has a field X and this has an onChange rule to populate field Y (from the same Position object)

Then, from Manage Configuration UI, field Y has an onChange UI rule to hide field Z.

Field Y populates properly, however, field Z is not being hidden.

Reproducing the Issue

1. Login to the system.

2. From Manage Data > Create Position

3. Populate field X, field Y is auto-populated (due to onChange rule from the field X in the Position object)

Since field Y is already populated - value has changed, we think that onChange UI rule for this field will trigger to hide field Z, however, the rule is not triggering.

4. Select field Y value from the UI, field Z will be hidden - onChange UI rule triggered.


For fields, onChange rules are triggered only when a field change event is triggered in the user interface (UI).


When using onChange rule, ensure that it is assigned only to the fields that require manual selection from the UI.
