Scripted Data Source Mock Object

shermand

I have a need to create a report that uses an external java object as its data source. No problem, I've got that working, binding the object to the IRunTask like

MyDataObject mdo = new MyDataObject();
// stuff happens...
Map map = task.getAppContext();
map.put("MyData", mdo);
task.setAppContext(map);

But that only works in the runtime environment where I have access to the REAPI (and the rest of my environment that populates "mdo". The report designer Preview view doesn't work, because there's no object bound for the scripted data source to use.

How do I detect that I'm running in the report designer, so I can do something clever to bind a mock data object, allowing the preview to work? If there's an answer to this somewhere already that I haven't found, please tell me where it is!

Thanks.

BIRT 2.3, upgrade likely soon.

One thing that I usually do is have a Java project in my same workspace in addition to my Report Project, and then in the Report Project properties under Project References, make a check mark by the Java project.

Now my BIRT designs can see Java classes and then I create a simple Java class with some stubbed in data.
