Async taskdefinitions.

Is there a way to find out if a task is async, the usecase is if a process has async task then i should throw error to the user. I checked TaskDefinition class there is no api to check if a task is async…

TaskDefinition is only the UserTask-specific bit. Inspect the actual ActivityImpl which is present in the ReadOnlyProcessDefinition (repositoryService):


public interface PvmActivity extends PvmScope {
 
  boolean isAsync();

Alternatively, you could add a BPMNParseListener (in 5.12, this will be a slight different name and approach, but the end-result will be the same) and inspect the XML-element or the intermediate model, so you can throw an exception when the process is deployed (as of 5.11):


/**
* @author Tijs Rademakers
*/
public class Activity extends FlowNode {

…

  public boolean isAsynchronous() {
    return asynchronous;
  }

In case you're using a version prior to 5.11, you can always inspect the "async" attribute in the XML-element, passed in the BPMNParseListeners…
