Re: Building a dynamic comma separated link list
I did this by subclassing RepeatingView and overriding
AbstractRepeater.renderChild as follows...
public class SeparatorRepeatingView extends RepeatingView {
private boolean firstChildRendered = false;
private String separator = " | ";
public SeparatorRepeatingView(String id, IModel model) {
super(id, model);
}
public SeparatorRepeatingView(String id) {
super(id);
}
@Override
protected void onBeforeRender() {
firstChildRendered = false;
super.onBeforeRender();
}
@Override
protected void renderChild(Component child) {
boolean childVisible = child.isVisible();
if (firstChildRendered && childVisible && separator != null) {
getResponse().write(separator);
}
super.renderChild(child);
if (childVisible) {
firstChildRendered = true;
}
}
public String getSeparator() {
return separator;
}
public void setSeparator(String separator) {
this.separator = separator;
}
}
Unfortunately, ListView marks renderChild as final, so this technique
won't work there.

I have the same problem.

Re: Building a dynamic comma separated link list
because it is a link list, not a word list. just chaining strings in an iterator would not be too hard, even for me ;-) igor.vaynberg wrote: > > if all you are doing is generating a comma separater list of words why > not do that in the model and simply use a label to spit it out instead > of a bunch of labels inside a listview > > -igor > > On Tue, Jul 8, 2008 at 9:46 AM, pixologe <[EMAIL PROTECTED]> wrote: >> >> Hi everybody, >> This is probably quite easy, but I do not seem to be able to find an >> elegant >> solution for this, so if anyone could give me a hint, I would highly >> appreciate it... >> >> I'd like to have a comma-separated link list with variable number of >> items >> generated by wicket. >> The link list is not a problem, just a link in the template and a >> listview >> applied to it: >> # asdf >> >> But what is a neat way to get the commas inbetween?

Re: Building a dynamic comma separated link list
if all you are doing is generating a comma separater list of words why not do that in the model and simply use a label to spit it out instead of a bunch of labels inside a listview -igor On Tue, Jul 8, 2008 at 9:46 AM, pixologe <[EMAIL PROTECTED]> wrote: > > Hi everybody, > This is probably quite easy, but I do not seem to be able to find an elegant > solution for this, so if anyone could give me a hint, I would highly > appreciate it... > > I'd like to have a comma-separated link list with variable number of items > generated by wicket. > The link list is not a problem, just a link in the template and a listview > applied to it: > # asdf > > But what is a neat way to get the commas inbetween?

Building a dynamic comma separated link list
Hi everybody, This is probably quite easy, but I do not seem to be able to find an elegant solution for this, so if anyone could give me a hint, I would highly appreciate it... I'd like to have a comma-separated link list with variable number of items generated by wicket. The link list is not a problem, just a link in the template and a listview applied to it: # asdf But what is a neat way to get the commas inbetween? My idea was to have a template like this: # asdf , A listview could be applied to "linklistitem" while "separator" could be set invisible for the last item in the list... But this seems quite complicated to me, is there something more elegant than this? Perhaps a way to add a String between to items of a listview when the view is being rendered?
