That worked!
I also had to move the declaration of tmpInstrument to inside the
populateItem method (otherwise all rows were the same).
Thanks!
(I feel this was a bit more complicated than it should be.)
Could this have been done with a CompoundPropertyModel and Loop:s
instead of ListView:s - using ognl like instrument[i].correlation[j] ?

actually, the string in the label is fine because the listview rebuilds its
items on every request so new labels will be created.
the problem is here:
ListView tmpCorrList = new ListView(ID_CORRELATIONS,
tmpInstrument.getCorrelations())
this is making listview use the same list w/out updating it on every
request, this should be a detachable model so that a fresh list is used on
every request:
IModel listViewModel=new LoadableDetachableModel() { Object load() { return
tmpInstrument.getCorrelations(); }}
ListView tmpCorrList = new ListView(ID_CORRELATIONS, listViewModel) {
...
};
hope this helps,

Hi,
I am also wrestling with the matrix beast and am still exploring my
options.
However i might be able to help you out.
In your code the label is given a string as diplay value. This string
is not updated when the item model is. So you should give the label
the model of the item.
If you want some fancy numberformatting to take place you can always
overwrite the getConverter() method of your label to convert the
bigdecimal to a string there.
Hope this helps.

Hi All,
With one page I'm displaying a matrix of numbers and I have a problem
updating/refreshing it. I roughly understand why it doesn't work, but I
don't know what the best/correct way to make it work is.
Basically I have a ListView of rows and the last column in each row is
in turn a ListView creating more columns to the right. That final
ListView is implemented with the code you can see below.
How was I supposed to have done this to have updating/refreshing happen
as automagically as possible?
(I'm using Wicket 1.1.1)
/Anders
ListView tmpCorrList = new ListView(ID_CORRELATIONS,
tmpInstrument.getCorrelations()) {
BigDecimal tmpCoefficient;
public void populateItem(final ListItem anItem) {
tmpCoefficient = (BigDecimal) anItem.getModelObject();
anItem.add(new Label(ID_COEFFICIENT, tmpCoefficient.toString()));
}
