Hi,
In my mssql database one text field is set not to allow nulls.
Also in my record form (ccs, vb.net) this field is set to required.
Now i would hope to see a error message if the field is left blank when submitting the form.
Instead I get a NullReferenceException error page.
Any idea what is wrong?
Thanks Dik

First suggestion is to check the properties of the text box on the form.
Check that the Required property is 'Yes' - if so, CCS should display an error message to the user if they try to submit the form with the field blank.

Sorry - you did mention that.
You're right - if the page is working properly, you do get a proper CCS error message saying "the value in field xxx is required"
The error message looks like it comes from .Net during the processing of the page, perhaps before anything is sent to sql server. Do you get the normal full-page .Net error message? If so, the section where it gives the line where the error arose would probably be helpful to see.

I hade another look. The problem is caused by a included (standard css menu) page. The page works fine without that menu. The menu seems to work fine except for the combination with this error processing.

Are you able to include that menu into another page? Does it work OK there?
If the problem is related to only one specific parent page that doesn't work, then possibly there is something conflictnig between the menu page and the page that includes it. Not sure if this would help but possibly there are conflicting control names, so first check if the controls on both pages have unique names. If they are unique then contact the support, as this could be some bug that only they can investigate.

Hi peter,
The problem is there with all pages, thats why i thought the validation did not work properly. Also I can reproduce the problem with a new page and a new includable menu. I will check with support,
