ClassCastException saving codegen-based DataGraph with ChangeSummary containing
an xsd:float
--------------------------------------------------------------------------------------------
Key: TUSCANY-1811
URL: https://issues.apache.org/jira/browse/TUSCANY-1811
Project: Tuscany
Issue Type: Bug
Components: Java SDO Implementation
Affects Versions: Java-SDO-1.0
Reporter: Ron Gavlin
This problem is similar to TUSCANY-1393 except the schema type in this case is
an xsd:float instead of an xsd:int. The fix involves adding the following lines
to DataObjectBase.java. If you would like me to submit a patch with a revised
testcase, let me know.
LINES TO BE ADDED to DataObjectBase.java:
protected void notify(int changeKind, int property, float oldFloatValue,
float newFloatValue)
{
eNotify(new ENotificationImpl(this, Notification.SET, property,
oldFloatValue, newFloatValue));
}
protected void notify(int changeKind, int property, float oldFloatValue,
float newFloatValue, boolean isSetChange)
{
eNotify(new ENotificationImpl(this, Notification.SET, property,
oldFloatValue, newFloatValue, isSetChange));
}
END OF LINES TO BE ADDED

P.S., below I have included the stacktrace for the problem.
