Unexpected behavior when deleting from layout.children

[paddymul]

I have encountered a bug when updating row contained in a column.

When r1.children[0] is deleted, r2 disappears and only the tools are left. I would expect a column with s1 above s2. Is deleting from the children array not supported?

Example IPython notebook https://github.com/paddymul/bokeh_bugs/blob/master/Bokeh%20row%20update%20artifact.ipynb

#this messes up the rendering row2
r1 = row(s1,s2)
r2 = row(s3)
displayed_obj = column(r1, r2)

handle = show(displayed_obj, notebook_handle=True)
time.sleep(5)
del(r1.children[0])
push_notebook(handle=handle)

Versions
python 2.7.11
IPython notebook 4.1.2
Bokeh 0.12.4

Thanks

Modifications of layout after initial rendering aren't well supported right now. This issue is likely a duplicate, but I will leave it open as there is substantial feedback here.

I agree it's probably a dupe of the other issues. I've moved it to 0.12.6 just to make sure it gets tracked in the next release cycle.

@mattpap do you have a test case for this? The original linked code is a 404 now.

Confirmed seems to be working now with this code
