Hi,
I have a browser with some kind of "buffer" where I can hold a value
selected from one of several list in the browser.
The buffer itself is implemented as a pane containing a list with only
one element in it, it is populated when I strongSelect (double click) in
one of the source list:
(browser transmit) to: #buffer; from: #PackagePane port:
#strongSelection; andShow: [:a |
a list
display: [:anEntity | {anEntity} ]
].
(browser transmit) to: #buffer; from: #ClassPane port:
#strongSelection; andShow: [:a |
a list
display: [:anEntity | {anEntity} ]
].
I also transmit from one list to the other with simple selection (click)
(browser transmit) to: #ClassPane; from: #PackagePane; andShow: [:b
| | gmlList |
gmlList := b list.
gmlList
display: [:anEntity | anEntity classes]];
It works "thusly" : if I click on a package in the PackagePane, its
class appear in the ClassPane.
If I double click on a package or a class, then it also appears in the
"buffer"
However, if I double click on a class, it goes correctly in the buffer,
but if after I single click on a package, the "buffer" is wiped.
This is not the intended behavior ...
Bug or feature?
and if it is a feature, how to get the feature I want?

Hi,
In this case, it is not a bug. The reason it gets "wiped" is that when you are
selecting a new package, you delete all ports from the target #ClassPane, and this in turn
triggers the transmission of nil to the #buffer pane.
What you need to do is to not transmit from #ClassPane to #buffer when the strongSelection
value is nil.
Here is a working example:
browser := GLMTabulator new.
browser column: #parent; column: #child; column: #buffer.
(browser transmit) to: #buffer; from: #parent port: #strongSelection; andShow: [:a |
a list display: [:x | {x} ] ].
(browser transmit) to: #buffer; from: #child port: #strongSelection; when: #notNil;
andShow: [:a |
a list display: [:x | {x} ] ].
(browser transmit) to: #child; from: #parent; andShow: [:a |
a list display: [:x | 1 to: x]].
browser openOn: #(1 2 3 4)
Btw, in the future, please post a full script (including initialization and opening). It
saves time to try and to provide the solution.
Cheers,
Doru

BTW, never thanked you for this one.
(actually, only today I realized that you answered. Too much running
around :-( )
It works.
Is there a reproducible process I could have followed to find out by myself?
Thanks anyway

Hi,
No stress with thanking :).
There is a little description of how transmissions work here:
http://www.themoosebook.org/book/internals/glamour/transmissions
What you could take away from this page is that you can have different strategies for a
transmission. The one used by #andShow: is the GLMReplacePresentationsStrategy. If you
look in the code, you will see that:
transmitIn: aContext
...
self transmission destination pane clearIn: aContext.
which sets to nil the values of all ports.
And any change, including changing to nil, will trigger a transmission.
The way around it is to guard the transmission with a condition.
Cheers,
Doru
