Hi, Indeed, seems that #resetElements is missing in GLMFastListOutlineDataSource. I added in in the latest version of Moose/FastTable for Pharo 6.1. Cheers, Andrei On Wed, Oct 18, 2017 at 12:05 PM, Peter Uhnák <i.uhnak@gmail.com> wrote:

Hi,

apparently it is not possible to update a GLMTabulator if it contains a list pane with separators. Tested in P6 & P7.

``` data := { { #one. #two. #three } asOrderedCollection. { #alpha. #beta } asOrderedCollection } asOrderedCollection.

browser := GLMTabulator new.

browser column: #list; column: #actions.

browser transmit to: #list; andShow: [ :a | a fastList withSeparators ].

browser transmit to: #actions; andShow: [ :a | a actionList act: [ :actionList | data last add: #dynamic. browser update ] entitled: 'Add Item'; act: [ :actionList | data last remove: #dynamic ifAbsent: [ ]. browser update ] entitled: 'Remove Item'. ].

browser openOn: data. ```
