INITIAL USER REQUIRED

Customizing the metamodel : Keywords for USRPROPS : INITIAL USER REQUIRED

This keyword specifies that at the creation time of the modeling element (either diagram, symbol, or definition), a value for the property must be supplied. If you do not supply it, and try to close the dialog by pressing OK, System Architect will give you a message that says "The xxx property must be supplied." You will not be able to click OK to close the dialog and create the diagram, symbol, or definition. You will either need to supply a value for the property, or cancel the dialog.

Example

DIAGRAM "Activity"

{

PROPERTY "Package" { EDIT OneOf "Package" RELATE BY "is part

of" INITIAL USER REQUIRED OVERRIDABLE }

PROPERTY "Activity Model" { EDIT OneOf "Activity Model" ReadOnly

INITIAL USER REQUIRED } ..}

In the example above, both properties "Package" and "Activity Model" must be filled in before you can click the OK button in the diagram dialog when creating an Activity diagram.

Note that in the example above, the property "Package" is also OVERRIDABLE, while the property "Activity Model" is not. The OVERRIDABLE keyword only has meaning to symbols drawn on this diagram that inherit values of the property from the diagram.
