CustomObjectType not storing value

jorell — Thu, 06 Feb 2014 01:48:26 GMT

I have created a custom object type for lists (ArrayList). I set these types in the process engine config as follows:VariableType listType = new CustomObjectType("list", List.class);List<VariableType> customVariableTypeLists = Lists.newArrayList(listType);processEngineConfigurationImpl.setCust

Hi,

May be you can follow item and message from ProcessEngineConfigurationImpl (activiti sources).


      variableTypes.addType(new CustomObjectType("item", ItemInstance.class));
      variableTypes.addType(new CustomObjectType("message", MessageInstance.class));

Regards

Thanks Martin. I think I was doing something similar to the Item and Message Types but maybe I missed something. Before I saw your message though I think I solved it by adding ListVariableType class which extends activiti's SerializableType:

<code>
import org.activiti.engine.impl.variable.SerializableType;

import java.util.ArrayList;
import java.util.List;

public class ListVariableType extends SerializableType {

@Override
public String getTypeName() {
return "list";
}

@Override
public boolean isAbleToStore(Object value) {
return value instanceof List || value instanceof ArrayList;
}

}
</code>

I then changed my process engine config setup to be:

<code>
VariableType listType = new ListVariableType();
List<VariableType> customVariableTypeLists = Lists.newArrayList(listType);
processEngineConfigurationImpl.setCustomPreVariableTypes(customVariableTypeLists);
</code>

So far this seems to work. Please let me know if you think there are any problems with this approach.

Seems to be a valid approach, thanks for sharing
