Thanks, I looked at the source and did the following:
public JalViewPanel(String id, DefaultMutableTreeNode treeNode) {
super(id);
activeNode = treeNode;
dlink = new DownloadLink("downloadMsf",
currentJalviewAlignment) {
@Override
public void onClick() {
String alignment = (String)
currentJalviewAlignment.getObject();
byte[] bytes = alignment.getBytes();
getRequestCycle().setRequestTarget(
new AlignmentRequestTarget(bytes,
"alignment.fasta"));
}
};
add(dlink);
WebMarkupContainer container = new
WebMarkupContainer("filename");
SimpleAttributeModifier modifier = new
SimpleAttributeModifier("value",
getRequestCycle().urlFor(dlink,
ILinkListener.INTERFACE));
container.add(modifier);
add(container);
}
the " getRequestCycle().urlFor(dlink, ILinkListener.INTERFACE) " part
works, when I put this is a label it renders the correct url which if
i paste it in the address bar goes to download the file.
However, in the way it is now wicket throws an IllegalStateException:
java.lang.IllegalStateException: No Page found for component
[MarkupContainer [Component id = downloadMsf]]
Any ideas?

Look at the source - it has getURL which is a protected method. If
you really can't figure out how to use urlFor(...) from the source -
then override getURL as such:
public CharSequence getURL() {
return super.getURL();
}
Make it public and use it to get the URL. You can ascertain all of
this from the source.

Thanks for the extensive feedback, but urlFor() does not accept

I tried being smart and did this (please correct me if this is
nonsense):
add(new WebMarkupContainer("filename").add(new
SimpleAttributeModifier(
"value",
dlink.urlFor(ILinkListener.INTERFACE))));
when I access the pages it gives the following error:
java.lang.IllegalStateException: No Page found for component
[MarkupContainer [Component id = downloadMsf]]
at org.apache.wicket.Component.getPage(Component.java:1755)
although the component is added to the panel. Here's the complete
code:
public JalViewPanel(String id, DefaultMutableTreeNode treeNode) {
super(id);
activeNode = treeNode;
DownloadLink dlink = new DownloadLink("downloadMsf",
currentJalviewAlignment) {
@Override
public void onClick() {
String alignment = (String)
currentJalviewAlignment.getObject();
byte[] bytes = alignment.getBytes();
getRequestCycle().setRequestTarget(new
AlignmentRequestTarget(bytes, "alignment.fasta"));
}
};
add(dlink);
add(new WebMarkupContainer("filename").add(new
SimpleAttributeModifier(
"value",
dlink.urlFor(ILinkListener.INTERFACE))));
}

You could always look at the source for how Link does it:
getURL() calls:
/**
* Gets the url to use for this link.
*
* @return The URL that this link links to
*/
protected CharSequence getURL()
{
return urlFor(ILinkListener.INTERFACE);
}
which calls:
Component#urlFor(this, ILinkListener.INTERFACE)
so you should call:
urlFor(dlink, ILinkListener.INTERFACE)

I'm feeling not really smart here, but that doesn't work. urlFor
needs
something like a irequesttarget. I tried something like this:
add(new WebMarkupContainer("filename").add(new
SimpleAttributeModifier(
"value",
urlFor(dlink.getRequestCycle().getRequestTarget()))));
but that gives me the url of the page, not the downloadlink.

urlFor(dlink)?

Ok, that is starting to work, thanks! Now I only need to get
the url
in
the
simpleAttributeModifier. This doesn't accept models but needs a
CharSequence, which does seem logical but how do I get the
actual URL
of
the
dlink model in there?

If I set setRenderBodyOnly(true) it doesn't work either, and
then it

not the

Betreff: inserting urls in script variables
Hi guys,
I'm trying to insert a download url in a piece of template
code.
The
template part looks like this:
<wicket:panel>
<span wicket:id="familyName"></span>
<applet code="jalview.bin.JalviewLite" width="100%"
height="750"
archive="jalviewApplet.jar">
<param name="file" value="{{URL HERE}}">
<param name="embedded" value="true"/>
<param name="showFullId" value="false"/>
</applet>
</wicket:panel>
The applet show a multiple sequence alignment that I would
like to
be
retrieved from wicket.
In my java code I have created a link that downloads the
file. This
works fine if I show the link on a page and click on it:
DownloadLink dlink = new DownloadLink("downloadMsf",
currentJalviewAlignment) {
@Override
public void onClick() {
String alignment = (String)
currentJalviewAlignment.getObject();
byte[] bytes = alignment.getBytes();
getRequestCycle().setRequestTarget(new
AlignmentRequestTarget(bytes, "alignment" + ".fasta"));
}
};
When I try to do the obvious, replace the {{URL_HERE}} part
with
<span
wicket:id="downloadMsf"></span> it complains about non-
valid XML
and
such.
Any ideas?
