Button (Write) - Error

I have a problem with Button (Write).

When I add this button on form and select variable then this error occurs on the form


I'm using compiled ScadaBR-1.1.0RC (JAVA8) from sources on windows 7 x64, JRE 1.8

On what configuration will it work ok ?

Good evening,
Use java 7 , and make sure that this button is written designator for binary tag.
