I'm creating an export pluging. I need to generate a "dropdown" list of categories based on XML data returned after clicking on a button. My code users LrHttp.get(url), but nothing happens after the button is clicked. Looking at the SDK and example code, LrHttp.get() must be wrapped in a task.
But I can't figure out how to correctly use LrTasks.startAsyncTask() after clicking a button on the export dialog. I don't want to launch a new dialog/window, which seems to be the examples in the SDK.
