Getting "Class null does not exist" when clicked on Submit

Hi All,

When trying to submit a assignment I am getting “Class null does not exist” as error message and when I traced it I can see the exception generated via activity called RecalculateAndSave at step 6.

The Fail message on tracer says “Trying to save an invalid page” .Checked Post activities and Post Data transforms, and commented all the steps in these, still getting this “null” at the top on click of submit button.

Only configuration Submit button is Click and Finish Assignment. Not able to find what is causing this error message. Tried clearing the cache, same result.

I have called a data transform on change of a property and it is in turn calling Data page built with Report Definition and when I remove this property I am able to Submit the assignment without this error. There seems to be a problem with Data Page/Report Definition I think.

Can anyone please help me on this?

Thanks in advance,

Sakhib Hussain

Hi @SakhibHussain

What is the mode of the data page that you are using, if its read-only then can you try to change it to other mode e.g. editable and then check if its still throwing error.

Thanks!

@AmarTiwari when checked a data transform calling this, I can see the error now coming because of these steps of DT. See attached screenshot.

@SakhibHussain Did you tried by commenting this step of DT, cause I don’t think there is any issue with this attached snippet. If you can elaborate more on your use case then might be we can check further.
