My general feeling, based on the couple of Wicket projects that I've been involved in, is that DataTable is best suited for a case where you want a fairly finished out-of-the-box implementation without a lot of custom tweaking or extra functionality. To make a grid in which you can repaint single rows I would try something that starts from more bare-bones components such as DataView and finding the relevant Items with IVisitor (operating e.g. on the DataView during the ajax request processing). We have done something similar but a bit simpler as we didn't allow editing the grid directly. Note the potential for race conditions if the user enters text and then, while the ajax request is being processed, clicks a row to be updated = boom. We worked around this by disabling the grid during ajax request processing (by using a layover being toggled by IAjaxIndicatorAware), but that cannot really be used if the grid itself is being edited and precisely editing it will toggle ajax events updating it.

[Wicket-user] Repaint single row of a DataTable
I searched for answers to this problem, but most responses were to repaint the whole table (or more specifically, the container holding the table). I am trying to make an editable grid. In addition to that, when some cell contents change, other cells may need to be repainted (they might contain computed values based upon values of one or more other cells). For performance, I don't want to repaint the entire table on each keypress, but repainting the single row won't be so bad. What could I do to repaint a single row of a DataTable? Don't use DataTable? but I think I still want a repeater and ultimatley it is the repeater's fault that I can't repaint because the MarkupFragmentFinder can't grab the markup because it uses the component's id to match up to the markup it finds and the id of repeater children will never match. It would need to know that it is a repeater child and use it's parent it to match the markup. Component.renderComponent is final and new MArkupFragmentFinder is hardcoded in there, so it doesn't look like I can create a custom MarkupFragmentFinder impl for this special case. Maybe I am seeing this from the wrong perspective? Could someone suggest an alternative to this approach? Basically, I like Datatable because it allows me to define each cell (and any number of them), but I want the ability to repaint only PART of the table...

Re: [Wicket-user] Repaint single row of a DataTable
this is tricky because datatable encapsulates a lot of this stuff so it will probably need something exposed for this usecase. if you create a quickstart that has a datatable, some bogus data, and some links in columns that should trigger a refresh i can play around with it and see what needs to be done. -igor On 7/19/07, ChuckDeal [EMAIL PROTECTED] wrote: I searched for answers to this problem, but most responses were to repaint the whole table (or more specifically, the container holding the table).

This doesn't work for you? What wicket version are you using?

Here's how the Column is created... basically it is adding a custom
Fragment to the cellItem. That Fragment represents a TextField onto which I
put the Ajax event.
columns.add(new AbstractColumn(new Model(Added)) {
public void populateItem(final Item cellItem, final String componentId,
final IModel rowModel) {
cellItem.add(new NumericTextFieldFragment(componentId, rowModel,
slocAdded, 6, 0) {
@Override
protected void decorateTextField(TextField tf) {
super.decorateTextField(tf);
tf.add(new
AjaxFormComponentUpdatingBehavior(onkeyup) {
@Override
protected void
onUpdate(AjaxRequestTarget target) {
MarkupContainer row =
cellItem.findParent(Item.class);
target.addComponent(row);
}
});
}
});
}
});
which throws this exception

Column one contains a button designed to repaint the row, the second column is a label representing the rowModel.
