Event ainsert_control_before

Description

This event is called before the insertion of a line in the database. It allows assigning values on properties, because no control has yet been done on the properties.

After this event is called, three controls will be done on every property of the class:

• The first control verifies if mandatory properties have been filled.
• The second control verifies if the expected format is respected (for example, the number of characters or digits, or the consistency of dates).
• The third control performs the other controls associated with the data types. This will trigger the CONTROL event on every property.

When nested classes must be controlled, such as a 3-level header / line / sub-line structure exists, the event is performed on the header level first, then on the first line and its associated sub-lines, on the second line and its associated sub-lines, and so on.

Context

The following variables or properties are available in the context:

• this refers to the current class. All properties can be found using the this.PROPERTY syntax.
• this.snapshot refers to the initial values for the current class. It allows a development partner to know if a modification was done on some properties.
• CURPTH describes the child class path if the method is called on a child class. If the method is called on the main class, CURPTH is empty.
• AEVENT is equal to AINSERT_CONTROL_BEFORE.
