Re: Wicket 6.x -> Wicket 8.x extensions NestedTree expand fails ( Components can no longer be added)
Sure, I was not so much thinking of me but other wicket users.. I've asked
around and at least here its not a "normal" wicket behavior that you could
break something by calling target.add(component).. And its not that I do
not want the error message, just to make it a little more clear to the
developer on whats wrong.. Not many would know that by calling target.add
you are breaking art because of internals of the tree..
A more pragmatic solution could also just to write in the java doc that
calling target.add + having expand in the newContentComponent method are a
no go and will break runtime.
right now expand java doc are just "Expand the given node, tries to update
the affected branch if the change happens on an AjaxRequestTarget
<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/ajax/AjaxRequestTarget.html>
."

Re: Wicket 6.x -> Wicket 8.x extensions NestedTree expand fails ( Components can no longer be added)
Hi Nino,
I've expanded the error message for now.
We could make that method on NestedTree lenient, i.e. catch the
exception and log the message instead.
But you could do that for yourself in your code too.

Compare this with 7.x:

- at this moment the node (and its parental branch) is not in the
component hierarchy yet
- #updateBranch() does not find any branch for the node's model and

So yes, we have a change, but no bug. In 7.x adding of the branch to the
ART was just ignored.
You can achieve the same in Wicket 8.x with the following:
protected Component newContentComponent(String id,
IModel node) {
if(haveClicked){
// #expand() can not be used, since it tries to add
the branch
// to the ART, which is not allowed during rendering
getModelObject().add(node.getObject());

return super.newContentComponent(id, node);

Re: AJAX & IllegalStateException: Components can no longer be added
Hi Sven, Hi, actually it is even more strict: Once the ART has started generating the response - including preparation of components - you can now longer add other components. This hasn't changed from 7.x to 8.x We were discussing on lifting this restriction, but this would come with some difficulties: what if a component in beforeRender() adds one of its ancestors to be updated? Thanks for the clarification! Cheers, Tobias Have fun Sven Am 25.05.2018 um 10:44 schrieb Tobias Gierke: Hi, Can someone please explain to me what's causing this exception (see end of this mail) when trying to add a component to an ART ? In http://apache-wicket.1842946.n4.nabble.com/Components-can-no-longer-be-added-td4662838.html Sven Meier said once rendering of components via Ajax has started, you cannot update components. but as can be seen from the stacktrace I'm still in the beforeRender() phase ... or is anything inside the beforeRender() code path already considered to be part of the rendering phase ?

Re: AJAX & IllegalStateException: Components can no longer be added
Hi, actually it is even more strict: Once the ART has started generating the response - including preparation of components - you can now longer add other components. This hasn't changed from 7.x to 8.x We were discussing on lifting this restriction, but this would come with some difficulties: what if a component in beforeRender() adds one of its ancestors to be updated?

RE: Components can no longer be added
Sven,
once rendering of components via Ajax has started, you cannot update
components.
But at the moment when this happens, we are in the onConfigure() part of the
lifecycle. Which is before onBeforeRender(), and hence components should've
have started rendering... but that is minor as...
You should just add all expanded nodes to your tree's model. That's faster and
won't trigger any updates:
Brilliant! I didn't realize that tree model was the *expanded* nodes, but it
makes sense since you now say it...
Thanks! This works great and gets round any other issues. :)
Cheers,
Col.

Hi,

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

Re: Components can no longer be added
Hi,
I am an expert in shooting myself in the foot with Wicket / Java
problems.
In a situation like this, I would do the same as you do - isolate the
pattern and make a quickstart. Unfortunately, this approach is full of
assumptions, and my statistics say that this succeeds only in 20% of
all cases.
So I usually have to do it the hard way: Take a copy of the
application and strip it down generation by generation until the
culprit is isolated in its most simplistic form.
I think in 50% of all cases, I could see my own fault. In the other
50% I submitted a Wicket jira issue, where again in 50% of these it
was my fault not Wicket.

Bernard

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,

RE: Components can no longer be added
Yeah, I know exactly what you mean - I'm sure it's something I'm doing! :)
I might have to do as you suggest... I was just hoping for a 'you'd only get
this error if you'd done something stupid like' and give me something to go
on! ;)
Cheers,

Subject: Re: Components can no longer be added
Hi,
I am an expert in shooting myself in the foot with Wicket / Java problems.
In a situation like this, I would do the same as you do - isolate the pattern
and make a quickstart. Unfortunately, this approach is full of assumptions, and
my statistics say that this succeeds only in 20% of all cases.
So I usually have to do it the hard way: Take a copy of the application and
strip it down generation by generation until the culprit is isolated in its
most simplistic form.
I think in 50% of all cases, I could see my own fault. In the other 50% I
submitted a Wicket jira issue, where again in 50% of these it was my fault not
Wicket.
Regards,
Bernard

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;
java.lang.IllegalStateException: Components can no longer be added
