Issue with Dropdown Grid

[geletkaf]

Hi Isomorphic,

our QAs have found small issue with Dropdown Grid. It is not possible to add back any column in one edge case as shown on picture below.

Could you please fix this issue ?
We use SmartClient Version: v10.0p_2017-08-15/PowerEdition Deployment (built 2017-08-15)

This should be fixed back to SGWT 4.1p/SC 9.1p in the nightly builds dated today (2017-10-24).
