DynamicMap frozen

Move slider, plot does not respond. Some error message is printed in the javascript console.

Here a minimal example to reproduce the bug. Overlaying a DMap comprising a NdOverlay over an Image does not work:

def curve(N): # Positional keyword arguments are fine
    xs = np.linspace(-10,10)
    return hv.Curve((xs,xs**(N)/(xs**(N)).max()))

def curves(N, radius=0.5): # Positional keyword arguments are fine
    return hv.HoloMap({n: curve(n+N)
             for n in range(0,3)}, kdims=['n']).overlay()

dmap = hv.DynamicMap(curve, kdims=[hv.Dimension('N', range=(0,10))])
dmap2 = hv.DynamicMap(curves, kdims=[hv.Dimension('N', range=(0,10))])
bg = hv.Image(np.random.random((10,10)))

Works:

bg * dmap #single curve

Does not work

bg * dmap2 #NdOverlay of curves

As far as I can tell this was fixed by https://github.com/ioam/holoviews/pull/967. Reopen if it’s still not working for you.

Perfect, thanks a lot @vascotenner. I’ll have a look today.
