isBuilt isBroken (C++ question)

[John Levon]

Angus recently added isBuilt() in controllers/ to make sure that
the dialog is built before changing its readonly stuff.

     60 template <class Base>
     61 void ControlDialog<Base>::show()
     62 {
     63         if (isBufferDependent() && !lv_.view()->available())
     64                 return;
     65
     66         setParams();
     67
     68         static bool isBuilt = false;
     69         if (!isBuilt) {
     70                 isBuilt = true;
     71                 view().build();
     72         }


unfortunately, the static seems to be sharing itself with all templatised
objects. How can we get the expected per-dialog isBuilt() functionality ?

thanks
john
