Q: Where is the PEF fileT gone? Is there an replacement? Is there a predicate that gives me the source location for the ID of a PEF?

A: fileT was replaced in version 2.6.0 with fileS or compilationUnitT. It is easy to migrate your predicates. There is also an overview of all the changes in JT 2.6.0 and related migration tips.

Q: Is there a way to generate the reverse indexes for a saved factbase? (Without JTransformer running.)

A: You need to load at least some excerpt of JT or CTC that performs the index creation. Without that, nothing will happen. The files you need to load are: ..\plugins\org.cs3.stransformer.java_1.0.3.200812151629\pl\main.ste.pl and ..\plugins\org.cs3.jtransformer_2.5.0.200812151629\engine\jt_engine.pl. Then you execute the query create_derived_facts to create the reverse indexes.

Q: Is there a way to generate the piece of Java code that belongs to an ID? (Without JTransformer running.)

A: Sure but you need to load at least the part of JT that defines the corresponding predicate. The two files mentioned above are enough. With that you can use gen_tree(ID, SourceCode) to regenerate the source code represented by the ID.
