> 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" 
>     baseClass="org.tigris.scarab.om.AbstractScarabModule"
>     interface="Module">
> ...
>     
> <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"/>
>     </foreign-key>
> ...
