Hello, I just ran into this issue and I thought I would share it. I thought I was loading my Behavior's into memory before using them but I wasn't. Here is what it looked like when it was failing.
I have some buttons that have behaviors set on them. When you control-click on them and look at Send Message, the commands that are associated with the behavior are there. So, I thought, the button is clearly linked to it's behavior. However using Dispatch to send the message results in "unhandled". It was not seeing the behavior's handlers. If I use the Send form I can see that the message is sent to the Button, but is not picked up by the Behavior, just the Button. Even if there is no handler for the message in the button. I can tell this by stepping through with the debugger. The debugger goes to the button's Script ( not the behavior's script ) even though the script is empty. It never makes it on to the behavior. I also noticed that I couldn't set Break Points in the behavior scripts in the debugger when this condition happened. They just didn't work. In all cases, I can it by simply resetting the behavior to itself, like so: *set *the behavior of tControl to the behavior of tControl So whats the deal? The button appears to be linked to the behavior? But I can't send it messages? And I can't set break points in the Behavior scripts. Well the problem is that the behaviors are not in memory when the buttons that use them are placed into memory. I thought that they were because I was loading the stack containing the Behaviors as part of the PreOpenCard in my first stack. So the Behaviors were in a second stack. And they were being referenced by the first stack. I think the docs point this out, but I was confused by the apparent linking, and the fact that I thought loading on PreOpenCard or PreOpenStack would be enough. But its not. I am including behaviors in a Library stack, instead of embedding them into a the stacks that use them. These are pure code Behaviors, no UI. And they are part of the larger feature set provided by the library. I wanted to be able to keep the library and it's behavior's separate. So either I will have to build a launcher file that just loads the library first or build in re-linking, which may not be a bad thing anyway. ???????????
