[javascript-dev] newdefault failed on button?

Hi,

Is there a special arguments I should pass to create a button or a message box with newdefault?

this.patcher.newdefault( 1000, 200,  "uslider" ) does work

but 
this.patcher.newdefault( 1000, 200,  "button" )
or
this.patcher.newdefault( 1000, 200,  "message box" )

does NOT work and return a "newdefault failed" error.

I have seen some old post mentioning a bug in newdefault for some objects. Is it still the same bug or am I doing something wrong?

Thanks

C
