Login in Web client in application server.

Classic Servoy
1

Hi All,

This problem is not at all occurring in Servoy Developer . When I am running from servoy application server in web client it is showing this problem . This is not occurring all the times . Some of the times it is occurring . After clicking the login button , It giving showing "Error calling Server " in small at the top . It is not at all going to the main form . If again I try to access the solution , it goes directly to the main form . Then again I have to restart the browser to resolve this Issue. There is nothing in the server log . I am having Servoy 6.0.6 and Mozilla Fire Fox 13.0.

Please provide some suggestion on this.

Thanks,
Ashutos.

Ashutos,

We would have to see it in order to debug it.
If you have exceptions in the log files, those may also be helpful.

Hi Rob,

Thanks for your reply . Actually most of the times when this issue appears , we donot see any thing in the server log . But again when I am trying to access the URL , the following Issue comes in the server log.

Hello,

Can anybody please suggest something, what exactly is causing this error.I am getting a similar log as posted by the original posters of this thread. Please give some ideas.

Thanks,
Sovan

that is difficult to say, because when that exact stack happens servoy is in a weird state
Because a null pointer should not happen in that method call. It looks like that client is already in shutdown/closesolution when it wants to render a page in a new window.

So if you have something reproducible on the latest releases of servoy please make a case.
