Form_For: Gotcha!

Hey!  Why is it that my form won't post unless I refresh the page?  The submit button simply doesn't respond to clicks. :(  Surprisingly, the answer was simple and it appears that it's not a Ruby on Rails issue, it's actually an HTML issue when using form_for.

If you're running into this issue, it would be my guess that your form is nested inside <table> tags.  That was my issue.  It seems that if you're going to put your form in a table, you *must* wrap the <table> tags with the <%= form_for @user do |f| %> ... <% end %> erb tags.

Here's a before and after of my issue (broken code and fixed code):

BROKEN CODE - Notice the form_for erb tags are nested inside the HTML table tags.

FIXED CODE - Just moved the form_form erb tags outside the HTML table tags.

If you know why this works, I'd love to hear your explanation.
