    1. COFirst of all, thank you for your help! While closer, this unfortionally didn't solve the case. When I added dependencies in the parent project, the project was complaining because of cyclic dependencies. Core and Android both depends on common. And I have most of the dependencies defined in the main project pom.

    2. CO@Aldrian You want `android.jar` and `core.jar` to end up in `common/target` but `common.jar` has dependencies to both `android.jar` and `core.jar`? OK, then you have a problem. Having dependencies defined in the main `pom.xml` is normally not a problem though. I think that you have to re-think about your model. An alternative would be to have a fourth module called e.g. `deployment` which will resolve all the other dependencies.

    3. COWell, common.jar doesn't depend on android.jar and core.jar, but android.jar and core.jar depends on common.jar , yeah I think I'll need a fourth model, I have a temporarily solution now with a Ant build script, going to post that as it might help figuring out how to compleatly do this in maven.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
