Build: Hula milestone build 8a.

The composite app fail to be deployed with the following scenario. It is different with issue 98275 and 
issue 99478. In those two cases, composite app can be deployed. 

Steps to reproduce it:

1) Create SynchronousSample2 sample project in IDE.
2) Create a new Composite Application CompositeApp2 under SynchronousSample2 directory.
3) Create a new BPEL Module BpelModule2 under SynchronousSample2 directory.
4) Create a new XML Schema file newXmlSchema.xsd under BpelModule2.
5) Add a new simple type "newSimpleType (restricts :int)", use existing definition: built-in type "int", 
into newXmlSchema.xsd.
6) Set SynchronousSample2 BPEL Process reference to BpelModule2.
7) Open SynchronousSample.xsd in Schema Editor. Import "newXmlSchema.xsd" as its Referenced 
Schema.
8) Customize the existing element "typeA". Change its type from "String" to "newSimpleType 
(restricts :int)", which is defined at the Referenced Schema newXmlSchema under Simple Type.
9) Open SynchronousSample.bpel in BPEL Editor. Double-click Assign1 to open the bpel mapper.
10) In BPEL Mapper, drag "inputVar" in the left pane of Source tree pane to "outputVar" in the 
Destination pane (the right pane).
11) Save all changes.
12) Deploy CompositeApp2.
Composite Application CompositeApp2 fail to be deployed.

The sample project Synchronous2.zip will be attahced.
