[jboss-jira] [JBoss JIRA] Created: (JBPM-1036) config-type schema declaration doesnt accept custom instantiator classes
config-type schema declaration doesnt accept custom instantiator classes
------------------------------------------------------------------------
Key: JBPM-1036
URL: http://jira.jboss.com/jira/browse/JBPM-1036
Project: JBoss jBPM
Issue Type: Bug
Affects Versions: jBPM jPDL 3.2.1
Reporter: Roland Huss
Assigned To: Tom Baeyens
Specifying a custom delegation instantiator with a fully qualified class name like in
<action config-type="com.consol.cmas.workflow.jbpm.exe.SpringInstantiator"
class="com.consol.cmas.projects.it.workflow.development.AssignCallToReviewerActionHandler"/>
doesnt work anymore because the schema allows value from a fixed enumeration only:
<xs:attribute name="config-type" default="field">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="field"/>
<xs:enumeration value="bean"/>
<xs:enumeration value="constructor"/>
<xs:enumeration value="configuration-property"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>
This contrary to the relevant code in the Delegation class this should work (and indeed
worked in some pre 3.2.1 versions):
Instantiator instantiator = null;
try {
// find the instantiator
instantiator = (Instantiator) instantiatorCache.get(configType);
if (instantiator == null) {
// load the instantiator class
Class instantiatorClass = classLoader.loadClass(configType);
// instantiate the instantiator with the default constructor
instantiator = (Instantiator) instantiatorClass.newInstance();
instantiatorCache.put(configType, instantiator);
}
} catch (Exception e) {
log.error(e);
throw new JbpmException("couldn't instantiate custom instantiator
'" + configType + "'", e);
}
So please either relax the schema restriction (which I highly prefer, since I rely on
using a custom instantiator) or remove the possibility to
use a custom instantiator.
