Hi All, Post our Version Upgrade to 7.9 we are not able to open our C

Are you trying to access the CDTs from the Application Designer interface (/design)? or the designer interface (/designer)?

Designer Interface

Can you try accessing the CDTs from the Application Designer interface and report back with the results?

Hi , From Application designer CDT's are opening.

Wondering Is it expected behaviour??

Yes This is expected behavior.

The expected behavior is that in /designer you can still navigate to and view the list of CDTs in the System tab under Data Management, but selecting and opening one of the CDTs from that page should open the CDT in the Data Type Designer interface (in /design)

Is this what you are observing?

Whats happening in my case is when i open a CDT from System Tab it opens a new tab and nothing is shown, where as i open the CDT from a package it opens properly.

After one of our environment upgrades, I had to clear my browser cache before all the designer interfaces worked correctly. Have you tried that yet?

There is a known bug where you can open the CDT the first time, but can not open it the second time when in /designer. /design is not affected
