When dynamic actions are displayed between two presentations, they are not displayed at all. Here is a snippet to reproduce this problem. I've committed a fix in the Moose51 repo.

browser := GLMTabulator new.

browser

row: #one; row: #two.

browser transmit to: #one; andShow: [ :a |

a tree

display:[ :x| 1 to: x ] ].

browser transmit to: #two; andShow: [ :a |

a tree

display: #(a b c);

filterOn: [ :text :each | each name includesSubstring: text ];

dynamicActions: [ :list | {GLMGenericAction new

action: [ ];

title: 'Action';

icon: GLMUIThemeExtraIcons glamorousBrowse;
