Hi, yes, it is better, but it does not work intuitively. Try the following: 1. execute your script, 2. click on 4 (selection), 3. click on 8 (selection), 4. click on 4 (deselection), 5. click on 4 (selection) You can see that the third list still keeps the number 8. It is necessary to deselect 8 in order to see 4. This part explains to me how the transmit works: ``` tabulator transmit from: #one; to: #three; from: #two; to: #three; transformed: [ :x :y | y ifNil: [ x ] ifNotNil: [ y ] ]; andShow: [ :a | a fastList display: [ :x | Array with: x ] ]. ``` By using #transformed: I can decide what to use (#one or #two). It is nice feature! I think what I need is having to possibility to change the third list also according to what list is active (#one or #two). In the first screenshot, the first list is active (blue border). In the second screenshot, the second list is active. So I would like to update the third list according to the active one. Is it possible? Thanks! Juraj

Hi,
That's actually the default behavior, but I see there is also a bug. Normally if you want to allow deselection in a presentation you should use allowDeselection. Just I see there is a bug in the fast table renderer because if I add #allowDeselection to the first presentation when clicking again on the selected element the selection port is not cleared. If you use #list instead of #fastList it works.
I think you can get the desired behaviur using this code:
----------------------------------------------------------------- tabulator := GLMTabulator new.
tabulator column: #one; column: #two; column: #three.
tabulator transmit to: #one; andShow: [ :composite | composite list allowDeselection; display: [ :x | Array with: x ] ]. tabulator transmit to: #two; andShow: [ :composite | composite list allowDeselection; display: [ :x | Array with: 2 * x ] ].
tabulator transmit from: #one; to: #three; from: #two; to: #three; transformed: [ :x :y | y ifNil: [ x ] ifNotNil: [ y ] ]; andShow: [ :a | a fastList display: [ :x | Array with: x ] ].
tabulator openOn: 4. -----------------------------------------------------------------
Cheers, Andrei

If you create the following Glamour browser:
``` tabulator := GLMTabulator new.
tabulator column: #one; column: #two; column: #three.
tabulator transmit to: #one; andShow: [ :composite | composite fastList display: [ :x | Array with: x ] ]. tabulator transmit to: #two; andShow: [ :composite | composite fastList display: [ :x | Array with: 2 * x ] ].
tabulator transmit from: #one; to: #three; andShow: [ :a | a fastList display: [ :x | Array with: x ] ]. tabulator transmit from: #two; to: #three; andShow: [ :a | a fastList display: [ :x | Array with: x ] ].
tabulator openOn: 4. ```
You will get the following browser:
<Screen Shot 2017-04-03 at 16.30.28.png>
if you then select 4, the third list appears. If you then select 8, the value is changed:
<Screen Shot 2017-04-03 at 16.29.38.png>
But since then, the third list does not change. It stays with 8 value forever.
Do I miss something? Should I define it differently? Or if it is a bug: Can you give me insights how to fix it?
Tested in the latest Pharo 6.
Thanks! Juraj
