Unlike the generic Sub Form element found in the community edition, AJAX Sub Form gives you the flexibility of dynamically populating a Subform as the value it watches changes.

Data to load by the AJAX Subform

The target's form Load Binder will be executed to fetch record matched from the properties defined in AJAX Subform.

Usage of Hash Variable

The use of Hash Variables inside the target form is permissible but may be limited due to the nature of how the form is loaded.

Example 1: One can use #requestParam.primaryKey# to access the record ID.

Example 2: One can use #form.tableName.fieldId[{requestParam.primaryKey}]# to access field value of the given record ID.
