Created by: Feroz Syed on 16-03-2010 01:34:51 PM Hi, We are getting the following error on Production environment occasionally. SERVER ERROR: An invalid element/exit state pair was returned: element was LiquidDamageMenu and exit state was null I went through the forums and CISCO docs, but could not find related information. Could some one help me out and let me know what could be the reason for this error. Please let me know if you need more information. Thank you! Regards, Feroz Syed

In a voice element (like a menu), if that element sends the first vxml page to the gateway, but wants Vxml Server to come back into the same element with the results collected from teh caller, then it returns a 'null' to Vxml Server (indicating VxmlServer should come back into that element).
Unfortunately, sometimes if you code something wrong in Studio, you might get an error of some sort that causes a null to be returned by the code when it shouldn't be.
This just happened in class this week when a student used a Menu element to collect a department name, and in the Option2Value setting in the settings tab of the element, they entered ' sales' (no quotes) - the error was caused because they had a leading blank space before the word 'sales'. They got the null exit state error that you got. It was hard to debug, because it's hard to see a blank space at the beginning of a line.
ANYWAY, in your case, it may occur occasionally because maybe it's a rarely selected menu option. But go into that element and look VERY CLOSELY at the settings. See if perhaps there's a leading or training space or something odd like that.
If all else fails, I would delete the element and re-code it from scratch.

I am able to re-produce this issue in the Dev environment. As you said, I have set the menu option value with space in it and tested, so here I got this error. It seems to be very odd and bug in CVP. It should have validation for trimming the value.
Anyways, in our Production environment, it is occuring occoasionally, I will delete these elements and re-code it from scratch. Regards, Feroz
