Hello again and sorry for the late reply and to hear your decision. I try to fix any problems that show up, however it is always good to have some help in reproduction (eg with projects), especially in issues that have never been reported before like yours here in this case. It might be that you are setting the variable at some point before it gets chance to initialize (although that is probably not the case here). It could also be that the variable is also set/overriden by something else (eg by a task or maybe it is a bound variable?). In either case, it is very hard to know without some reproduction steps please, and it is very unlikely that it just resets itself to null for no reason just after you set it.
