Repeater component with dynamic column list
Hello,
my goal is to display a table with dynamic number of columns (and of course
rows) based on my EntryData class.
ArrayList<EntryData> entries = ...;
public class EntryData implements Serializable
{
private String entryID;
private ArrayList<FieldData> entryFields;
[...]
}
where
public class FieldData implements Serializable
{
private int fieldId;
private String fieldLabel;
private String fieldValue;
[...]
}
I would like to have a table presenting entryID and values of all the fields
for each entry on the list.
Entry ID | entryFields[0].fieldLabel | ... |
entryFields[x].fieldLabel
------------------------------------------------------------------------------------------------
entries[0].entryID | entries[0].entryFields[0].fieldValue | ... |
entries[0].entryFields[x].fieldValue
...
entries[y].entryID | entries[y].entryFields[x].fieldValue | ... |
entries[y].entryFields[x].fieldValue
I am not really experienced in Wicket and tried to find some Repeater class
example to use it as a base for building my own solution. Unfortunately I
didn't find anything that suits my needs.
I would like to know if it would be possible at all to use one of the
repeater control family member to display such data structure. I'll
appreciate any help and sample code.
Kind regards
R

I've spent a lot of time trying to figure out what's wrong with code and
markup but didn't notice this typo.
Thanks Martijn
You might want to spell wicket correctly in your markup. wikcet is not
the valid xmlns prefix :)

Hi Janos,
I did what you advised me to do but got the following exception (in this
case I used a list of 3 entries with 3 fields):
Unexpected RuntimeException

that you have added a component in code but forgot to reference it in the

I would use a custom panel component which would have the following markup:
<tr>
<th>Entry Id</th>
<th wicket:id="heading">
</th>
</tr>
<tr wicket:id="row">
<td wikcet:id="cell>
</td>
</tr>
And the code:
RepeatingView heading = new RepeatingView("heading");
for (FieldData fd : entries.get(0).entryFields) {
heading.add(new Label(heading.newChildId(), fd.fieldLabel));
}
add(heading);
RepeatingView row = new RepeatingView("row");
add(row);
for (EntyData ed : entries) {
WebMarkupContainer r = new WebMarkupContainer(row.newChildId());
RepeatingView cell = new RepeatingView('cell");
row.add(r);
r.add(cell);
cell.add(new Label(cell.newChildId(), ed.entryId));
for (FieldData fd : ed.entryFields) {
cell.add(new Label(cell.newChildId(), fd.fieldValue));
}
}
You need the WebMarkupContainer because it will get the same markup that the
"row" repeatingview gets.
This is quite basic, there is some room for optimization but I hope you get
it.

Posted by Jonas <ba...@gmail.com>.
We've created a grid with dynamic columns similar to
org.apache.wicket.extensions.markup.html.repeater.data.grid.AbstractDataGridView,
except, of course, that the cell populators (the columns) don't come from
a fixed array, but from a (dynamic) list.
