Connector end detection during transformation

[cpelster]

Hi there,

i have a class with a connection to itself. during the template the connection template is called twice for
beginning (source) and end (destination). Is there any chance to know whether i'm at the beginning ot the end?

in my exmaple I want to insert a primary key when the class references itself and the key gets insertet two times.


thanks in advance,

Add something like this the following to the top of your connector template.

Code: [Select]

%if connectorSourceElemGuid != classGuid%
%endTemplate%

Hi Simonm,

i tried it, but it never gets called.
Correct me if I'm wrong but when the class references itself connectorSourceElemGuid and connectorDestElemGuid always are the same as classGuid?

Thanks,

The same "error" occurs in the DDL transfomation. When you have an association to a class itselft, you can see the ForeignKey statement twice in the intermediary file. But it appers only one attribute in the table ... so the error doesn't appear in the resulting table . In a class to class transformation the attribute appears twice

Did you find a solution to the self reference in the meanwhile? I hit the same problem.
Thanks for sharing the solution (if there is one) ;-)

Hi,

we solved the problem by writing our own more powerful transformation language as a plugin, but i think the problem was resolved by EA in build 605 or 606, i saw something concerning the connector ends in the changelogs.
