[Openoss-devel] Soap generator fails if artefact in 'root' package (org.tmforum.tip) was Soap Generator fails on empty model

[Craig G. (opennms) <cg...@op...>]

Xose,
Further to my previous post and perhaps more worrying. I find I get the 
same error if I create any artifacts in the 'root package'.

to recreate;
1. create a new tigerstripe model
2. enable the soap generator
3. in the soap generator settings in tigerstripe.xml ensure root package 
is set
<property name="ROOT_PKG">org.tmforum.tip</property>
4. in tigerstripe model create an entity in package org.tmforum.tip
5. generate model

you get the following error
ERROR ? [15-Aug-2012 16:28:22.760] - Unexpected error while merging 
'templates/dependencyAnalyzer.vm' template: Invocation of method 
'constructClosure' in  class 
org.eclipse.tigerstripe.generators.xml.filters.DependencyAnalyzer threw 
exception java.lang.StringIndexOutOfBoundsException: String index out of 
range: -1 @ templates/dependencyAnalyzer.vm[7,21]. Generation may be 
incomplete. [2012-08-15 16:28:21.976+0100]

     at 
org.eclipse.tigerstripe.generators.xml.helpers.XsdReferencesMgr.<init>(XsdReferencesMgr.java:67)

this is caused by the following code at XmlSchemaHelpers.java line141 
when pkgOrSession='org.tmforum.tip' and root='org.tmforum.tip'

         if (pkgOrSession.startsWith(root)) {
             loc = pkgOrSession.substring(root.length() + 1);
         }

Cheers
Craig
