broken combatibility to 3.2: incompatible types error when compiling BasePeer classes

                 Key: TORQUE-76
                 URL: https://issues.apache.org/jira/browse/TORQUE-76
             Project: Torque
          Issue Type: Bug
          Components: Generator
    Affects Versions: 3.3-RC1
            Reporter: Ronny Völker
             Fix For: 3.3, 4.0

When compiling Scarab with Torque3.3rc1 lots of incompatible types error are returned.
When compiling with Torque3.2 everything is compiled successfully.

The root cause are changes of torque/templates/trunk/src/templates/om/Peer.vm in r373352.
In this revisions some class casts have been removed which seem to be required in BasePeer
classes, if inheritance and interfaces are used in the schema mapping.

Sample compilation output:
    [javac] C:\elaxy\svn\scarab_trunk\src\java\org\tigris\scarab\om\BaseIssuePeer.java:933:
incompatible types
    [javac] found   : org.tigris.scarab.om.Module
    [javac] required: org.tigris.scarab.om.ScarabModule
    [javac]                 ScarabModule temp_obj2 = temp_obj1.getModule();
The buggy line using Torque3.3rc1 templates:
Issue temp_obj1 = (Issue) results.get(j);
ScarabModule temp_obj2 = temp_obj1.getModule();

The sameline using Torque3.2 templates:
Issue temp_obj1 = (Issue) results.get(j);
ScarabModule temp_obj2 = (ScarabModule)temp_obj1.getModule();

The interface of Issue.getModule() (inherited from BaseIssue):
    public Module getModule()

The related sections in the schema.xml of Scarab:
<table name="SCARAB_MODULE" idMethod="idbroker" javaName="ScarabModule" 
<table name="SCARAB_ISSUE" idMethod="idbroker" javaName="Issue">
    <column name="MODULE_ID" required="true" type="INTEGER"></column>

    <foreign-key foreignTable="SCARAB_MODULE">
        <reference local="MODULE_ID" foreign="MODULE_ID"/>
