FIX: Moving a subtype connector in an ORM source model may delete subtype definitions and duplicate subtype connectors (319227)

This article was previously published under Q319227 SYMPTOMS In an Object Role Modeling (ORM) source model, when you
move a subtype connector, you may also delete the subtype definition and
duplicate displays of the subtype connectors. CAUSE When you move a subtype connector (for example, to switch
the connector to a more central connection point for better alignment), at
least one end may temporarily become detached from any connection point. This
action causes the affected subtype not to be treated as a subtype in the
underlying model, and the subtype definition and any duplicate displays of the
subtype connector are removed. RESOLUTION Subtype connectors attach to connection points on the
supertype and on the subtype. These connection points are hidden by default,
but you can display these connections by clicking Connection Points on the View menu.
Before you reposition a connector to a subtype
for which you have supplied a subtype definition, copy the subtype definition
either to the Clipboard or to a text box, so that you can paste the definition
back into the subtype definition pane when you have completed the move. If you
have duplicated the subtype and supertype (on another page, for example), drag
the Subtype Relationship arrow from the ORM source model stencil, and then connect the arrow to
the object types to redisplay the connection.
NOTE: You can right-click the subtype or supertype, and then click Show Relationships; however, this action displays any associations played by the
object type, also.
The "More Information" section of this article
includes two detailed scenarios for how to work around this problem.
STATUSMicrosoft has confirmed that this is a bug in the Microsoft
products that are listed at the beginning of this article.
This bug
was corrected in Visual Studio .NET (2003).
MORE INFORMATIONScenario 1: Move a subtype connection where the subtype has a subtype definition Page 1 of an ORM source model displays the fact type Person has Gender, the object type Woman, and a subtype connection from Woman to Person. Also, a definition exists in the Subtype definition field of Database Properties for Woman (for example, each Woman is a Person who is of Gender F). You want to move the subtype connector in one of the
following ways:
- Indirectly, either by moving the subtype or by moving the
supertype shape
- Directly, by disconnecting the subtype connector at one
end
To work around the problem, follow these steps:
- Select the subtype definition in the subtype definition pane, and then press CTRL+C to copy the
subtype definition to the Clipboard.
- Reposition the subtype connector.
- Position the insertion point in the subtype definition pane
where you want to paste the subtype definition text, and then press CTRL+V to
paste the subtype definition from the Clipboard.
Scenario 2: Move a subtype connection where the subtype is duplicated elsewhere Page 1 of an ORM source model displays the fact type Person has Gender, the object type Woman, and a subtype connection from Woman to Person. Page 2 displays a duplicate of Person and Woman, but does not display the subtype connection between these
objects. To display this connection on page 2, drag the Subtype Relationship arrow from the ORM source Model stencil, and then connect the arrow
from Woman to Person. You want to move the subtype connector on page 1 in
one of the following ways:
- Indirectly, either by moving the subtype or by moving the
supertype shape
- Directly, by disconnecting the subtype connector at one
end
However, if you move the subtype connector on page 1, you will
remove the duplicate subtype connection on page 2 (the subtype connection
remains in the underlying model, but is not displayed for the duplicate
connection). To move the subtype connection, and then restore the
display of the duplicate connection on page 2, follow these steps:
- Follow the steps in scenario 1 to move the subtype
connection.
- On page 2, drag the Subtype Relationship arrow from the ORM source model stencil, and then connect the arrow
from Woman to Person.
NOTE: This problem also occurs when the duplicate subtype or supertype
appears on the same page as the original.
