Thank you for your reply.
But I did not specified the small icon image path.
If I create new project and try to create new diagram, this error occurs also.
If I remove custom extension jar from the Activiti Designer Extensions of the User Library,
everythign works right.
I created clean install of eclipse, and retried, but the same result.
Below is my source code of extension, but nothing special.
@Runtime(delegationClass="com.test.MyUserTask")
@Help(displayHelpShort="test", displayHelpLong="test long")
public class MyUserTask extends AbstractCustomServiceTask {
@Property(type=PropertyType.COMBOBOX_CHOICE, displayName="Task Type", required=true)
@Help(displayHelpShort="Select a type", displayHelpLong="Select a task type")
@PropertyItems({"Create Item", "type1", "Assign Scope", "type2"})
private String taskType;
@Property(type=PropertyType.BOOLEAN_CHOICE, displayName="Is Multi-Scope?", required=true)
@Help(displayHelpShort="multi-scope task", displayHelpLong="multi-scope task. ")
private String multiScope;
@Override
public String contributeToPaletteDrawer() {
return "myTask";
}
@Override
public String getName() {
return "my User Task";
}
//@Override
//public String getSmallIconPath() {
// return super.getSmallIconPath();
//}
}
I don't know the reason.
Can you help me?
