Re: Error Message from ResourceLink within a portlet
sorry, two pieces of code are:
final WebResource csvsrc = new WebResource() {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
public IResourceStream getResourceStream() {
// TODO Auto-generated method stub
IStringResourceStream srs = null;
if (true) {
CharSequence cs = getCsvData();
srs = new StringResourceStream(cs,
"text/csv");
srs.setCharset(Charset.forName("UTF-8"));
} else {
}
return srs;
}
};
ResourceLink rlink = new ResourceLink("myresource", csvsrc) {
@Override
public void onClick() {
}
};
this.add(rlink);
and:
/**
* @see org.apache.wicket.IResourceListener#onResourceRequested()
*/
public final void onResourceRequested()
{
Random random = new Random();
if (random.nextBoolean()) {
this.error("blablabla");
} else {
resource.onResourceRequested();
}
onClick();
}
