little triangle 'explaining' the direction of association text

[Arnoud_B]

In the wizard to create a Basic class diagram with multiplicities an association is shown and the text explains:
"The association is named and an indicator shows how to read the relationship between the two classes."
I think that is VERY useful but I cannot find how to activate this indicator. If I create a new association the indicator is not shown and I do not see any option to activate. It is probably very simple but I have been looking for ages and cannot find it

You have to right click on the name of the association on the diagram to set the reading direction.

Since EA stores this info only on diagram level, and not on association level, I generally discourage the use of this reading direction arrow.
(you can make two diagram showing the same association, but with a different reading direction.)

Hi Geert, thanks for the response I found it now it was well hidden ;-)
I agree with you that because it is stored in an inconvenient place and is therefore not maximal useable. however it is useful as changing the 'direction' of the association means something else in UML.
So I will use it but I'll note in the back of my mind the risks it creates.
Or do you have an option in SparxEA that delivers the same value with less risk?

You can avoid the issue alltogether by not naming your association, but instead name the roles.

For one client that didn't want to give up association names, we opted to use the navigability instead of the label direction.
