Re: Show Stacktrace in ErrorPage
You can add a RequestCycle listener that returns your custom page when an exception is thrown: http://blog.wizche.ch/2011/12/wicket-15custom-exception-page.html Hello, my application runs in deployment-mode and if an exception is thrown, wicket shows his internal error page without the stacktrace. Is there any possibility to show this stacktrace in this wicket error page? How can I get the stacktrace of an exception to show it in a custom error page?

Re: Components can no longer be added
Hi,
once rendering of components via Ajax has started, you cannot update
components.
AbstractTree#expand() is a convenience method that updates the expanded
branch automatically, hence you get the IllegalStateException.
You should just add all expanded nodes to your tree's model. That's
faster and won't trigger any updates:
tree.getModel().addAll(addNodes);
If you always start with all nodes expanded, you might want to use a
custom set, which inverses its contents. See
org.apache.wicket.examples.tree.FooExpansion for inspiration.

Sven

Wicketeers,
I have another hard-to-track down issue.
To make matters worse, I've actually taken this code/pattern, put it into a
quickstart - and what do you know - it works fine...! This means I have no way
to recreate this error in a demonstrable way. Hopefully if I throw this out
there, someone might be able to describe the error and I can then determine
what I'm doing to cause it. Unfortunately google has zero results for;
+Components can no longer be added +wicket
Anyway... the exception I'm getting is;

It is caused when refreshing a table-tree component, that had previous rendered
correctly and had successfully expanded the nodes. This problem happens when
the table-trees parent component is refreshed, in which the table is rebuilt
from new, and replaced the old table. Having debugged the code, it's something
to do with the AjaxRequestHandler that has been retrieved - in that it's
components are 'frozen'. It's odd as I'm in the onConfigure() part of the
lifecycle, and therefore components should be okay to be added - especially as
they are brand new components. Could the AjaxRequestHandler being retrieved be
the wrong one, stale one?
List I said - I can't recreate it in a Quickstart, so there is obviously
something else in the 100k+s of the projects code that is doing something else
to mess it up.
The 'Tree Utils' class looks like this;
public class TreeUtils {
@SuppressWarnings(unchecked)
public static void expandAll( AbstractTree? tree ) {
// stupid cast!! Has to happen for use to retrieve the roots,
generically.
AbstractTreeObject castTree = (AbstractTreeObject) tree;
Iterator? roots = tree.getProvider().getRoots();
while( roots.hasNext() ) {
Object root = roots.next();
expandNode( castTree, root );
}
}
private static void expandNode( AbstractTreeObject tree, Object node) {
tree.expand(node);
Iterator? children = tree.getProvider().getChildren(node);
while( children.hasNext() ) {
Object child = children.next();
expandNode( tree, child );
}
}
}
Any pointers and tips would be greatly appreciated.
Cheers,
Col.

We are glad you like Wicket! Keep making good software with it and spread the word! Also don't hesitate to say a good or bad word about it at Twitter, just mention #ApacheWicket.

response headers in Wicket 6
Hi, I'm converting one of our apps from 1.4.7 to 6.12. the old code extended
WebResource. I changed it to extend ByteArrayResource. I changed
setheaders to setResponseHeaders. But the code inside, I am not sure how to
change to Wicket 6 as the parameters are very different.
@Override
protected void setResponseHeaders(AbstractResource.ResourceResponse
data,
IResource.Attributes attributes) {
super.setResponseHeaders(data, attributes);
response.setAttachmentHeader(defaultFileName);
response.setHeader(Cache-Control, No-Cache);
response.setHeader(Cache-Control, No-Store);
}
How can I adapt the last three lines to Wicket 6?

Re: response headers in Wicket 6
Second question (the first is still open), in 1.4.7 the page object supported a removePersistedFormData() method and the TextField has a method setPersistent() on it. Both appear gone, and I don't see anything in the6 or 1.5 conversion guides about them. What is the replacement? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/response-headers-in-Wicket-6-tp4662864p4662866.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: response headers in Wicket 6
For the last two lines :
data.getHeaders().addHeader(key, value);
or
((WebResponse) attributes.getResponse()).addHeader(key, value);
for response.setAttachmentHeader(defaultFileName);
(from WebResponse.java)
setHeader(Content-Disposition, attachment + ((!Strings.isEmpty(filename)) ?
(; filename=\ + filename + \) : ));
