How to query database for candidateUsers

[ykphuah]

I need to dynamically query the list of candidateUsers/candidateGroups from database. Can this be done?

I tried the following:

package com.mastersam.adama.server.activiti.delegate;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;


public class CandidateGroupDelegate {
    private Logger logger = LoggerFactory
            .getLogger(CandidateGroupDelegate.class);

    public String getGroup() {
        logger.error("getGroup");
        return "requester";
    }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then I have this in my activiti-context.xml

   <property name="beans">
         <map>
            <entry key="candidateGroupDelegate" value-ref="candidateGroupDelegate" />
         </map>
      </property>
…
<bean id="candidateGroupDelegate"
      class="com.mastersam.adama.server.activiti.delegate.CandidateGroupDelegate">
   </bean>
‍‍‍‍‍‍‍‍‍‍‍

After which I set in the candidateUsers property of the Process

${candidateGroupDelegate.getGroup()}

or

#{candidateGroupDelegate.getGroup()}

both doesn't work, it doesn't call my function.

I tried searching and it doesn't seems like the candidateUsers and candidateGroups parameter supports spring expression, is that right?

Any other ways to accomplish what I want?

I noticed that this works for the candidateGroups parameter in UserTask, but not for the candidateStarterGroups in the process.
