I have a text input that sets a token which is used in my panels, as a manual filter the user can input. By default I want this to be blank so that no results are filtered out. However, if I do this the dashboard won't autorun, it'll stay on "Search is waiting for input...". If you put "&form.token_name=" in the URL it works, but I want the dashboard to autorun by default with no value in the filter token.
Yeah, I know I can do that, but I'd really like it to work when left blank. I just think it looks nicer and more intuitive - I don't want users wondering why it hasn't worked when they haven't put anything in the filter box.
@sillingworth - any other method is going to be much more complicated. For instance, you could have a second token, the REAL search token, and preset that. Then, on change of your input token, you could update the value in your actual search token.
However, be warned that if you want to do any validation on the values input by the user, that you need to be careful to avoid a race condition (token 1 sets token 2 which sets token 1 forever).
