Custom Objects are not working after upgrade of 6.3.1
We have seen that most (5x) custom objects successfully worked after upgrade, but there are some restrictions.
Anything that was imitating the Save button, for example, wouldn't work because it is no longer there.
As Ilya notes, you would need to detail the custom objects, what they're doing, and how their failing.
I would give the smallest code
Which is using for exporting a mail merge with the help of custom object
This is throwing an error. And the error log says the user do not have a permission. ( I am a system admin).
Well, I do not think that this small piece of code would give us any idea of what is wrong.
That code will you shared will work everywhere.
Do you do some redirection inside code? or accessing another layer or frame?
