Hi Jesús
Thanks, it helped a lot (and it works for me now)!
My code looks like:
def get_image(self, item, theme):
if isinstance(item, Action):
image_deferred = defer.succeed(item.icon)
elif isinstance(item, StationModel):
image_deferred = defer.succeed(item.resource)
else:
image_deferred = None
return image_deferred
Pretty simple.
Best Regards,
Kristian
