Problem with custom task in Designer

Hi,

  I worked through the money-tasks example and constructed some custom tasks for the designer, and all went well.

  However, when I create a task containing only a BOOLEAN_CHOICE, it does not get saved in the XML output.  I looked for an error, but didn't see anything.  However, when I add a TEXT property, the boolean shows up.  Just thought I'd let others know.  Example code is below:

Works:
package edu.mayo.mi3c.xb3.designer;

import org.activiti.designer.integration.servicetask.AbstractCustomServiceTask;
import org.activiti.designer.integration.servicetask.PropertyType;
import org.activiti.designer.integration.servicetask.annotation.Help;
import org.activiti.designer.integration.servicetask.annotation.Property;
import org.activiti.designer.integration.servicetask.annotation.Runtime;

@DeweyTask
@SuppressWarnings("unused")
@Runtime(delegationClass = "edu.mayo.mi3c.xb3.task.ClassifySeriesTask")
@Help(displayHelpShort = "Classify a series", displayHelpLong = "Assign tags to the BO associated with this series")
public class ClassifySeriesItem extends AbstractCustomServiceTask {

   @Property(type = PropertyType.TEXT, displayName = "Extra Tags", required = false, defaultValue = "")
   @Help(displayHelpShort = "Tags", displayHelpLong = "Comma-separated list of extra tags to add to the BO")
   private String tags;

   @Property(type = PropertyType.BOOLEAN_CHOICE, displayName = "Wait for completion", required = true, defaultValue = "true")
   @Help(displayHelpShort = "Wait for task completion", displayHelpLong = "If checked, the workflow item does not complete until DEWEY executes the required functionality.  If unchecked, execution immediately continues and the next step in the workflow is assumed to be a 'Receive' task")
   private Boolean synchronous;

   @Override
   public String getSmallIconPath() {
      return "icons/folder_fill_16x16.png";
   }

   @Override
   public String getName() {
      return "Classify Series";
   }

}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Doesn't write out the 'synchronous' tag in the XML:
package edu.mayo.mi3c.xb3.designer;

import org.activiti.designer.integration.servicetask.AbstractCustomServiceTask;
import org.activiti.designer.integration.servicetask.PropertyType;
import org.activiti.designer.integration.servicetask.annotation.Help;
import org.activiti.designer.integration.servicetask.annotation.Property;
import org.activiti.designer.integration.servicetask.annotation.Runtime;

@DeweyTask
@SuppressWarnings("unused")
@Runtime(delegationClass = "edu.mayo.mi3c.xb3.task.ClassifySeriesTask")
@Help(displayHelpShort = "Classify a series", displayHelpLong = "Assign tags to the BO associated with this series")
public class ClassifySeriesItem extends AbstractCustomServiceTask {

   @Property(type = PropertyType.BOOLEAN_CHOICE, displayName = "Wait for completion", required = true, defaultValue = "true")
   @Help(displayHelpShort = "Wait for task completion", displayHelpLong = "If checked, the workflow item does not complete until DEWEY executes the required functionality.  If unchecked, execution immediately continues and the next step in the workflow is assumed to be a 'Receive' task")
   private Boolean synchronous;

   @Override
   public String getSmallIconPath() {
      return "icons/folder_fill_16x16.png";
   }

   @Override
   public String getName() {
      return "Classify Series";
   }

}

So you're saying the BOOLEAN_CHOICE doesn't write to the XML if it's the only property for that task? That sounds like a bug to me. Could you file an issue in Jira for this?

Also, out of curiosity, I noticed you have an @DeweyTask annotation. Have you made any changes to Designer to somehow use that annotation? It might interfere somehow.

Hi, I'll put something in Jira.  Since I'm creating a whole group of tasks in Designer, I've been trying various ways to simplify my work (and learn more about annotations!), I didn't change Designer at all though.

Hello blezek,
I am also working on custom task in designer by money-task example.I compiled it and the .jar file is created in the target folder.
Now i dont understand what to do next to use the money-task custom task???
Can you please highlight how can money-task by used..

niktyagi88,

the information you are looking for is in the userguide. You need to add the Jar to a specific User Library in Eclipse and then include the library in the build path of the Activiti Designer projects.

Thnks tiesebarrell,
I proceed with the process given in the user guide.The icon of the money-task is seen in the designer and now i can configure by its properties.When i create the activiti test case by the diagram and run it,I receive the exception.The exception trace is as follow:

Apparently the AcmeMoneyJavaDelegation doesn't have fields for alle the options you can set in the properties screen. Since Activiti is instructed to inject all of the fields, it fails when it encounters a field that doesn't exist in the Delegation class. So you should either add the fields to the delegation or remove them from the CST itself.

Thnks for ur suggestion tiesebarrell.
Now my delegate class look like


package org.acme.runtime;

import org.activiti.engine.delegate.JavaDelegate;
public class AcmeMoneyJavaDelegation implements JavaDelegate {
   private String accountNumber;
   private String comments;

   private String withdrawlLimit;
   private String expiryDate; 
@Override
public void execute(DelegateExecution execution) throws Exception {
  
  System.out.println("The delegrate class is called");
}
}


But i am facing an error

@Override

  System.out.println("The delegrate class is called");
}
}


But i am facing an error

Hi,

  The problem is that your JavaDelegate class must use Expression instead of String.  Your class should look like this:

package org.acme.runtime;
import org.activiti.engine.delegate.DelegateExecution;
import org.activiti.engine.delegate.JavaDelegate;
public class AcmeMoneyJavaDelegation implements JavaDelegate {
   private Expression accountNumber;
   private Expression comments;
   private Expression maximumProcessingTime;
   private Expression vipCustomer;
   private Expression accountType;
   private Expression withdrawlLimit;
   private Expression expiryDate; 
@Override
public void execute(DelegateExecution execution) throws Exception {
  
  System.out.println("The delegrate class is called");
                System.out.println ( "The accountNumber is: " + accountNumber.getValue(execution).toString() );
}
}

Be aware that Activiti only passes these as static strings, they are not evaluated (so $foo is not expanded).

Best,
-dan
