I am receiving error “Invalid property type: TStrings” when I close the schema modeler. My server project has several units which have schemas and none of them return this error. This error began to occur after installing the latest update.

Can you provide direction on how to correct this condition?

Hi,

Can you specify what build are you installed, pls? .1589 or .1597?

if you are using .1589, can you retest this case with .1597, pls?
