Question

What will happen if I check for a Boolean (Either True or false) in Exclusive Split and that boolean value is empty but not T/F?

0

obj/Attribute is in the split and if Attribute(Boolean) is not assigned to obj at anytime while creation. Where the control will go? Will that go to false side only? or it is struck ?

It will create a null Pointer Exception.

Setting a boolean with empty will get you something like "Null pointer exception, boolean cannot be set to null" if the flow gets to the exclusive split you will see an error in the server console log something like "Null pointer exceptionNo outgoing document defined".

You can prevent this by checking for !=empty first

Stephan Bruijnis is correct if you create an object in a way where you can actually leave the boolean empty, or if you apply entity access and you cannot read the boolean attribute at all an error will occur.

However, if you use a default pattern by creating an object and not assigning a specific value to the boolean attribute + the user has access it will just follow the path of the default value you have set on when defining the attribute. Which will also be the value that gets saved if you commit.
