IOException loading DataGraph containing a deleted dataObject whose property
type extends a complexType w/simple integer content
--------------------------------------------------------------------------------------------------------------------------------
Key: TUSCANY-1842
URL: https://issues.apache.org/jira/browse/TUSCANY-1842
Project: Tuscany
Issue Type: Bug
Components: Java SDO Implementation
Affects Versions: Java-SDO-Next
Environment: Windows XP, Sun JDK 1.5.0_09
Reporter: Ron Gavlin
Priority: Critical
Fix For: Java-SDO-Next
In the test method, testComplexTypeWithSimpleContentExtensionChangeSummary()
listed below, a DataGraph is created with a dataObject whose property type
extends a complexType with simple integer content. After the dataObject is
deleted, an attempt is made to save and load the DataGraph. While the DataGraph
is being loaded, an unsuccessful attempt is made to convert a zero-length
string into a BigInteger.
Any suggestions on how to best fix this are most welcome.
Thanks,
- Ron
