Cannot draw connection from port to port [message #1431183]

Hello,

I have created a component with a subcomponent. Both have a port (untyped). Now I want to draw a connection between the ports. But there is no possibility to do this.
If there is an Edge which can be started on the one port I cannot connect it to the other port.

Is this a bug or do I have to do something manual here?

Best Regards
Bjoern

Hi Bjoern,

I don't know your odesign, but to create edge you need an "Edge
Creation" tool to be defined. Is it the case? For edge reconnection
there is another tool named "Reconnect Edge".

Best Regards.

Hi,

this is something I do not understand. I just want to get my thoughts into a diagram. Therfore I need to draw a line / a connection from one port to another. I don't want to to define or create an edge before.

By the way: What is an reconnection edge?

Does your Viewpoint Specification Model (VSM, the .odesign file) contain
an EdgeMapping (with source/target mapping corresponding to your ports)
defined in the VSM ? It is required to indicates how to find elements to
represent as an edge. See [1].

Does your VSM contain a style as children of this mapping ? It is
required to indicates how to draw the corresponding edges. See [2].

Does your VSM contain a an "Edge Style" linked to the edge mapping you
want to create ? It will add a palette entry to allow the user to create
those type of edges. See "Edge Creation" in [3].

In the Viewpoint Specification Model (.odesign file), the "Reconnect
Edge" is used to allow end-users to change the source and/or target of
an edge by moving the corresponding end onto another graphical element.
If a tool is specified to handle the user’s reconnection attempt, it
will be invoked with all the appropriate information so that it can
execute the corresponding semantic change. See "Recnnect Edge" in [3].
