In LiveCycle ES it is possible to track the dependencies of parent forms to form fragments and vice versa using the functionality in Workbench ES.
In LiveCycle ES2 it is also possible to view the form fragments used by a parent form in Workbench > Form Design > Properties:
It is not possible to track the dependencies from a form fragment to see in which parent forms the fragment is used. This is due to the architectural changes related to the new application model in LiveCycle ES2.
In LiveCycle ES3 it is again possible to track the dependencies of parent forms to fragments and vice versa.
If you have a requirement to track the dependencies from fragments to parent forms in LiveCycle ES2, then you can do this using the LiveCycle API using code similar to below:
ResourceRepositoryClient repositoryClient = new ResourceRepositoryClient(myFactory); String fragmentUri = "/Applications/TestApplication/1.0/fragments/AddressFragment.xdp"; List relations = repositoryClient.getRelated(fragmentUri, false, Relation.TYPE_DEPENDANT_OF);
Here is a full sample class you can execute to test this functionality against a running LC server (you will need to adjust the settings for your environment): ListDependencies.java
