[jboss-jira] [JBoss JIRA] Created: (JBRULES-805) Array of object not supported by contains
Array of object not supported by contains
------------------------------------------
Key: JBRULES-805
URL: http://jira.jboss.com/jira/browse/JBRULES-805
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Environment: linux, java1.4
Reporter: ahmed yehdih
Assigned To: Mark Proctor
when the array is an array of object like String we get
java.lang.ClassCastException

example: assume we have a class message
class Message{
String [] mess;
}
rule "test"
when
Message(mess contains "HELLO")
then
..
end
the reason is the test in the org.drools.base.ValueType class
else if ( clazz.isAssignableFrom( Object[].class ) ) {
return ValueType.ARRAY_TYPE; the test will be satisfied only for array of
java.lang.Object and not for others object
a simple solution is to modify this test in
else if ( clazz.isArray() && clazz.getComponentType() instanceof Object) {
return ValueType.ARRAY_TYPE;
