This doesn't work if I have 0 tag for a post or 0 categor for a post. Also it display only 1 row with all categories ( I have removed tags part to make the example ). I'm not saying that you are wrong because I've to learn the differences between them, I'm only exposing results :) Thank you for your advice, I will take a look at it. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
