Hi,
When I run my solution with NGClient, I get the error: “solutionModel is not defined”. What is strange is that I do not get the error with WebClient.
Is it a known limitation?
Best regards,
No, solution model works with NGClient as well.
Where is the code that tries to use it?
Any other errors in the app. server log file before that one?
The full log is the following:

Do you think that is the reason of the solutionModel error?
So do you have any idea of what happened?
What version of Servoy do you use? (I need this info to understand the NullPointerException)
Can you post that line at “…/forms/Qformulaire.js#471” that accesses solutionModel?
From the first stack trace it looks like “Qformulaire” form is trying to access solutionModel in the onHide of form “PopQuestionnaire”. But I don’t see a reason for that to fail.
(I was on vacation for a while, sorry for the late post)
Hi,
Thank you for your reply!
The version I use is Servoy 8.1.2
The line is:
solutionModel.removeForm("Qformulaire")
Does that help?
It looks like the connection to client is being closed from the server (I think) for some reason but a few websocket messages from the client still arrive.
One such message that was being handled manages to execute a form hide (but the client is already closed or closing => solutionModel is already cleaned-up/undefined), while the other fails completely because when it arrives more state is already destroyed.
I can’t see exactly what triggers the close of the solution/session though. Can you reproduce this? A case (ideally with a sample) would be appreciated.
There was a small fix in 8.1.3 that fixed something like this - when the solution was doing log-off server-side after showing an external URL (so it redirected to some other site + logoff) in a event handler while there were still pending calls from the client to be executed (user for example clicked something more in browser or some other websocket traffic was pending). But I am not sure that this is the case for you as well; it might be something different.
I see there is already a similar case SVY-11151.
So you can add a sample to that one as well instead of creating a new one.
