I made a custom block which is installed via a package. Everything works fine except the layout of some elements of the add/edit form layout.
What is strange is that I installed the exact same block via the application folder and everything looks perfect (I only changed the namespace in controller.php).
Why these differences ?
You have to find code responsible for loading css file in block controller (in addEdit()) and change fifth argument of $al->register() to your package handle. This way it tells to look for a css file in your current package folder.
