Accepted Solution Posted: 1 year agocorte PEGA replied to VTALUKDARPlease try the following: 1. Log out of Designer Studio. 2. Shut Down the Virtual Machine. 3. Restart the Virtual Machine. 4. Try opening a Flow Rule again. If that fails, please download and use the Linux Lite VMhttps://pega.app.box.com/v/llvm-lsa731 Posted: 1 year agocorte PEGA replied to VTALUKDARUsually that issue is caused by an improperly loaded style sheet. You should also try clearing the browser cache before restarting the VM. Also try using a different browser to try and reproduce the problem.

Yes I faced two seperate types of issues in the Linux Lite VM: (1) Flow rules not loading properly, and showing improper format. (2) Flow rules are loading properly, but cannot reference any other flow rules. Whenever a sub case is defined , SAVE of the rule prompts a NULL Pointer Exception. Both issues were fixed, once I deleted the VM instance, and re-created a new VM Instance of Linux Lite. Thanks for the help ! Posted: 1 year agopedel PEGA replied to VTALUKDAROops. Looks like you already did what I suggested below. 8>< - - - - - - snip - - - - - - ><8 Have you tried different browsers? Firefox and Chrome are installed on the LLVM. Do they show the same problem? Can you create a new LLVM instance and see if the problem occurs again?
