Wow! Cool you've found it!
@Doru: The mondrian DSL in Roassal assigns a copy of the shape for each element. This is
different from what we had in Mondrian. The reason for copying the shape, is that having a
copy makes singular update much much easier, i.e., temporarily changing the color of an
element.

The problem was that, while constructing the nodes in
the Mondrian builder, the shape assigned to each was a copy of the current shape. But this
was a normal copy that didn't copy the chain of shapes. That means that all nodes were
connected to the current shape and not to a copy. So, for each node you had a shape like
this:
A ROBox -> a ROLabel -> a ROChildrenShape -> a ROChildrenShape -> a
ROChildrenShape -> ... lots of ROChildrenShape ... -> a ROChildrenShape ->
aRONullShape.
So when a node was update, ALL the shapes of the other nodes were updated too.

Hi Roberto,
I checked and yes, there was a little ugly bug :P I commited a new version, can you try
and see if it works now, please?

Hi guys,
I'm using Roassal to build a visualization that looks like the following:
http://www.xconomy.com/wordpress/wp-content/images/2012/11/skeuo-calendar.p…
I create two ad-hoc layouts (i.e., extending the ROGridLayout) to individually layout
days inside months and months inside years.
I have a piece of code that looks something like:
view shape rectangle withText.
view nodes: nodes forEach: [ :aGroupOfObjects | | innerNodes |
innerNodes := do something with aGroupOfObjects.
...
view shape rectangle size: 25; withCenteredText.
...
view nodes: innerNodes.
view layout: ROMonthLayout new.
]
view layout: ROYearLayout new.
view edges: ...
Notice that I want the both the outer node (i.e., the month container) and the inner
nodes (i.e., days) with labels.
The problem is that when I set both nodes with labels the view takes time to be generated
and interactions become impossible (i.e., the whole image actually becomes slow and you
can no longer drag around shapes in the view).
I explored the issue a little bit and discovered that it might be something related to
ROShape>>chainedDrawOn:for: and the way Roassal handles shapes with
"nested" shapes (i.e., when 'next' is not a RONullShape .
I inspected one of my outer nodes and discovered that I have a chain such that
'outerNode next' is a ROLabel and the ROLabel has a ROChildrenShape as next and
the next of the ROChildrenShape is a RONullShape .
Have you ever experienced such a problem? Do you know how can I handle that? Do you see
any potential problem in the snippet I posted above?
Cheers and thanks in advance,
Roberto
