Bug? Generic VST2 editor not processing text input correctly

Problem: Cubase 6 doesn’t appear to process text input correctly in the generic editor for VST 2 plugins.

Reproduction: Add a VST 2 plugin of your choice to a track, switch to the generic editor, find a parameter that is NOT a percentage, double-click on the value text and enter a new value. The input is processed as a percentage anyway - for example, entering 50 will always move the control to the middle even if this is meaningless for the parameter in question. Cubase does not appear to call AudioEffectX::string2parameter to process the input.

Anyone else noticed this?
