Hi Jesse,
One way of doing this I picked up on the Laszlo forum which claimed to
be the only memory leak safe way of empty'ing datasets which is basicaly
your own conclusion in your last paragraph:
var dsPntr = dsProspect.getPointer();
while( dsPntr.p.hasChildNodes() ) {
dsPntr.p.removeChild( dsPntr.p.getFirstChild() );
}
dsPntr.destroy()
Not sure who made the original post...
Gr, Arne
