Values linked to variables are not always assigned in both directions when WPF in combination with DependencyProperties is used

Summary

If a DependencyProperty is used to assign a value inside a WPF to another DependencyProperty that is linked to a variable in the SCADA, values are not written if one DependencyProperty is triggered. The value inside the WPF is changed properly, but the value is not written to the variable.

Description

If a DependencyProperty is used to assign a value inside a WPF to another DependencyProperty that is linked to a variable in the SCADA, values are not written if one DependencyProperty is triggered. The value inside the WPF is changed properly, but the value is not written to the variable.

Solution

The behaviour of the WPF element was changed slightly to address this. Now, change notifications are only blocked on property level (and for the runtime element) instead of globally locking all change notifications.
