Have checked in an attempt at a fix for main - still need to test that fix properly and to port to the vNext branch
vNext work for #13
update for #13 - we need to pass this update call on even in the null…
Had to patch the fix.
Because of the way Dialog some Elements hold on to their own UIViews - e.g. Floats hold on to their own sliders - then all update methods must be able to handle the current cell being null - so Martin's original fix in StackOverflow is optimal!
Pushed and presume this is verified
