I am unable to a filter for an aggregate on Outsystems 10. Is anyone able to help?

  

The properties bar for entering an expression for filters in an aggregate is blank. I have tried restarting my computer, reinstalling outsystems, trying different versions, however, nothing seems to be working. Is there any way you could help.

Hello Yassar,

have you double clicked on the filter expression? Did it opened the expressioni editor? What's your Service Studio version?
