Summary0004189: tjvupdown fails when setting min/max
DescriptionSetting min and max produces confusing effects because the Borland's ancestor (TCustomUpDown) has its own (private) copies of the member variables FMin and FMax that are not updated by the SetMin and SetMax methods in TJvCustomUpDown.

The problem shows (among other cases) when setting Min/Max to a value lower/greater than the default. For example after setting Max to 1000 (the default is 100) the Direction parameter of the OnChangingEx event will take the value updNone instead of updUp as it should when Position is between 100 and 999, etc.
Additional InformationTo solve the probleam SetMin and SetMax must update the ancestor properties before doing any processing, as in:
