Invalid Hservice

[PouyaMoradian]

Hi @AndreasFagschlunger

I'm using close command on my device and after that, I cant open and register that device again and all I get is:
WFS_ERR_INVALID_HSERVICE(-22)

Can you explain a little about the correct flow of this scenario ?

Hi @PouyaMoradian!

I just quickly looked into the matter, and XfsServiceManager keeps a list of XfsServices opened. When you execute a CloseCommand, the service isn't removed from it's internal list so it's reusing an invalid instance. If you call shutdown on the XfsServiceManager and then re-initalize it, it may work. Since on shutdown the internal list is cleared.

I have to think about this issue and how to deal with it. Easiest way might be to remove the service internally from list, when a close command returns. Or it could be removed when an Open command arrives.

You will hear from me,
with best regards
