Glamour problem. Presentations not being updated - Moose-dev

14 Sep 2011


      Hi, 
I'm again working with glamour. 
I have this browser:
buildBrowser 
    | browser |
    
    browser := GLMTabulator new 
    	column: #list;
    	column: #detail;
    	yourself.
browser transmit 
    	to: #list;
    	andShow: [ :presenter | 
    		presenter list
    			title: [ self crudClass description label ]; 
    			act: [ self addItem ] 
    				icon: LWUIIcons / #listAdd 
    				entitled: 'Agregar'; 
    			selectionAct:[ :presentation :anItem | self removeItem: anItem ] 
    				icon: LWUIIcons / #userTrash 
    				entitled: 'Borrar';
    			updateOn: LWUIItemRemoved from: [ self announcer ];
    			display: [ self itemsSortedIfNecessary ] ].
    	
    browser transmit 
    	to: #detail;
    	from: #list;
    	andShow: [ :presenter | 
    		presenter magritte
    			title: [ :anItem | anItem asString ];
    			updateOn: LWUIItemRemoved from: [ self announcer ];
    			act: [ :presentation :anItem | self removeItem: anItem ] 
    				icon: LWUIIcons / #userTrash 
    				entitled: 'Borrar' ].
    	
    ^browser
(don't take into account the spanish words :) )
the idea is this: I'm making a simple CRUD for some classes... and this is the problem:
1) when calling "removeItem", I update the list, and everything works fine... but I removed an element from the list, so... selection shouldn't be valid anymore,  and the magritte presentation should be erased... and this does not happens. 
2) I added the #updateOn:from: send to magritte presentation to see if something happens... and no, it never receives the update :(
so... I think there is a need to fix both problems: list presentations should trigger transmit update if selection no longer valid, and magritte presentation should react to updates. 
Is that ok?
cheers,
Esteban
