Accessing tags with repeaters
Hello
I have a simple repeater that dynamically assemblies a row of a table from default components (labels, panels, buttons etc) The row is part of the dataview.
RepeatingView row = new RepeatingView("row");
[in Dataview's populateItem I set components]
row.add(some_component);
row.add(some_other_component);
[..]
Markup is this:
<tr wicket:id="dataview">
<td wicket:id="row"></td>
<tr>
Now, in the dataview's onPopulateItem, i'd like to set attribute to the <td> tag based on some property of the populated object.
Sadly there's no markup id for the <td>, nor any accessible component in that tag that I could handle with AttributeAppender.
Is there any other way to do that? Can I somehow get the <td> handle?
Regards
Michal

I'm glad you figured it out!
In my example 'td' should really be named 'tr' because it is a row, not a
cell.

Hi Martin,
Thanks, I got that already :)
I seem to fire questions before deeping into the matter carefully.
At first I tried overriding onComponentTag on the repeater object, but then realized that in this case it's only the
container (just as your WebMarkupContainer), so the attributes should be added to the child components. No it works ok :)
All in all I got it just as you propose, thanks for the idea and sorry for firing questions early :)
Regards
Michal

Actually here you need something like:
WebMarkupContainer td = new WebMarkupContainer(row.newChildId());
td.add(some_component);
...
So you can do: td.add(AttributeModifier.append(...));
or even override its #onComponentTag()
