The first thing I see, though probably unrelated to not getting the label
to show up is:
> PdfLinkPanel panel = new PdfLinkPanel(componentId, new
> Model(""+rowModel));
Just do PdfLinkPanel panel = new PdfLinkPanel(componentId, rowModel);
The row model is already a Model, and appending an empty string to it
doesn't do what it looks like it might be doing. But, you aren't using
that passed in model anyway, so the point there is somewhat moot, unless
it's resolving the model by traversing up the component hierarchy. In the
PdfLinkPanel, the call to super should probably be super(id, model);
I'm not sure if the email stripped out your html, but I don't see an anchor
tag or a tag for the label in the PdfLinkPanel markup. It should be
something like:
<a wicket:id="downloadLink"><span wicket:id="outputText">Label Shows Up
Here</span></a>
I'm just seeing:
# <wicket:id="outputText"/>

Hi, first; i need the download option for each row in the table, Not in the
filter.
In my Java program i did:
@SuppressWarnings({ "unchecked", "rawtypes", "serial" })
public TextFilteredPropertyColumn getLink(String header,String sort,String
field) {
return new TextFilteredPropertyColumn<String,IModel>(new
Model<String>(header), sort, field) {
@Override public void populateItem(final Item<ICellPopulator<String>>
item, final String componentId, final IModel<String> rowModel){
PdfLinkPanel panel = new PdfLinkPanel(componentId, new
Model(""+rowModel));
item.add(panel);
}
@Override
public String getCssClass() {
return "text";
};
};
}
And in PdfLinkPanel
<html xmlns:wicket>
<wicket:panel>
# <wicket:id="outputText"/>
</wicket:panel>
</html>
public class PdfLinkPanel extends Panel {
public PdfLinkPanel(String id, IModel<String> model) {
super(id);
super(id);
DownloadLink downloadLink = new DownloadLink("downloadLink",new
File("mann_oe.pdf"));
Label label = new Label("outputText","Factuur");
add( downloadLink );
downloadLink.add(label);
But instead of a link in my column table i only see this [cell]
It does work but does not show the invoice number as a link (just only the
constant [cell] )

Re: Need a link in a dataview filter column

Did you want to put the link in the rows of the datatable or in the header
row with the filter column itself?
If you're just adding the links to the data rows, I typically use a
Fragment when making custom DataTable columns. You could create a new
fragment that has the link that will call your service method to return the
pdf for the provided row model. So in your column definition in
populateItem, you do something like:
cellItem.add(new PdfLinkFragment(componentId, fragmentId, YourPage.class,
cellItem.getModel());
And define PdfLinkFragment to extend Fragment. This fragment would have
your link defined for the provided model.
I hope this makes sense, I'm not in a place where I can give more detailed
code right now.
Alternatively, you could just create a PdfLinkPanel and add that to the
cellItem instead of using a fragment. Both options would accomplish the
same thing.
If you need to put the link in the header column, you'll probably have to
do some subclassing of FilteredAbstractColumn and probably make your own
header bar.
