Hi,

I noticed that in a association the arrow shows when the navigable checkbox is NOT checked.

Shouldn’t it be the other way around, that the arrow shows when the checkbox is checked?

Yee,
According to the UML 1.3 Spec, Associations are bi-directional when they are shown w/o arrow heads, and hence when you uncheck the ‘navigable’ property , an arrow head pops up on the other end to show the uni-directional nature.
