So I have a simple DB and an AccountManager for that DB. In AccountManager I have a grid where all the accounts pop up when queried and spinners to serve as search filters since I only want to search it by a specific field. I started off with just one spinner to filter the accounts by STATUS. So now it would filter the accounts based on that STATUS. If I chose Status 1 on the spinner it would only show accounts with STATUS 1 and so on.
So like any newbie to programming, having a nice working code I went ahead and cloned it to make another spinner to use as another filter for searching. This time to search accounts by their TERMS. So now the plan was to use the two spinners either INDIVIDUALLY or TOGETHER to filter the accounts. The only problem being that once I cloned the necessary codes and tweaked it a bit now nothing shows on the grid whether I use just one of the spinners or both.
I'm not sure if my two spinners are conflicting each other or cancelling each other out, if anyone can see the problem or have their own recommendations on how to do the search filter thing better I'm all ears as well. Also feel free to ask for any other bits of the code for reference.
