Re: strange error

[Bas Gooren]

Hi!

The last line of the stack trace indicates that a NullPointerException is
occurring; My guess is that this happens inside your code, probably in the
constructor of assets.endpoints.OIDCConsensusPage

You’ll have to get your hands on the full stack trace (when not in the
logs, simply set a debug breakpoint in your constructor, and step through
the code) to find out exactly where the NPE is thrown.

Met vriendelijke groet,
Kind regards,

Re: Strange error

[Martin Grigorov]

For 1.5 I can say that this is definitely true, the code is in
org.apache.wicket.page.PageAccessSynchronizer.adapt(...).new
PageManagerDecorator() {...}.commitRequest()

The related code in 1.4 is in
org.apache.wicket.Session.requestDetached() but I'm not sure what
exactly happens there.

 I tend to agree that odds of a Wicket bug in this area are small. Can you
 think of a case in your application where a component has a HashMap of
 objects which have a TreeMap of objects? Maybe the source of this collection
 within your application is the problem.

Yeah, is 1.4, but it should be behind pagemap lock..

Re: Strange error

[Dan Retzlaff]

How reproducible is this? I don't know how the serialization process itself
would cause this, but if it's intermittent then maybe there's a threading /
synchronization bug somewhere.

Hi!

I don't know how to reproduce it... and I wonder, because there is
pagemap lock, what else can be modifying stuff during page
serialization?

Re: Strange error

[Dan Retzlaff]

I tend to agree that odds of a Wicket bug in this area are small. Can you
think of a case in your application where a component has a HashMap of
objects which have a TreeMap of objects? Maybe the source of this collection
within your application is the problem.

Re: Strange error

[Martin Makundi]

I believe there are numerous such Maps, but what can be the cause of
concurrent modification? Wicket should be allowing only single thread
operating on the object?

Re: Strange error, cannot modify hierarchy

[andrea del bene]

Hi Brown,

I've never used isTransparentResolver but I know it was removed in 
wicket 1.5 because it was it was quite confusing for users:


http://apache-wicket.1842946.n4.nabble.com/remove-MarkupContainer-isTransparentResolver-td1909586.html

You can try to replace it using one of the solutions described here:

https://cwiki.apache.org/WICKET/migration-to-wicket-15.html#MigrationtoWicket1.5-MarkupContainer.isTransparentResolver%2528%2529removed


I am shooting in the dark but I thought I would post the error I am
getting.

I get this error.  Cannot modify component hierarchy after render phase
has started.  The full stack trace is at the bottom of this post.

During the form submission process (user clicks on link) then I get the
error above but ONLY when I have a dynamic component with
isTransparentResolver = true.

If I restructure my hierarchy such that transparentResolver is false
then I don't get the same error.   Why do you think I get the error?

...
  final WebMarkupContainer container = new WebMarkupContainer(
container ) {
public boolean isTransparentResolver() {
return false; // true causes error
}
 @Override
 public boolean isVisible() {
 return logic();
 }
 };

version cant change then anymore)

Re: strange error

[Douglas Ferguson]

Yes.. 

This page works fine, this was a user submitted error from the field, even the 
user can't recreate it.

For awhile now I've been seeing Component doesn't exist on page errors 
intermittently cropping up. This is the first time I've seen this one.

 org.apache.wicket.WicketRuntimeException:submitted http post value 
 [radio-32719] for RadioGroup component [1:subPanel:linkForm:siteWide]
 is illegal because it does not contain relative path to a Radio componnet.
 Due to this the RadioGroup component cannot resolve the selected
 Radio component pointed to by the illegal value.
 A possible reason is that componment hierarchy changed between rendering and 
 form submission.

Re: Strange error

are you using the sysdeo tomcat plugin for eclipse.
We had the same issue y'day and doing this fixed the issue
 - compile the files in the DevLoader.zip and jar it in place it in

 Here's the fragment markup, fragment Java code, and exception name:

 Very simple.. if I move the Form outside of the fragment into the ListView,

 Thoughts?

Re: strange error

[Martijn Dashorst]

Probably you have a repeater serving out those ajax thingies.

1. Make sure you have a reuse items strategy set
2. Make sure you don't get 2 events right after one another: the link
that is clicked and a seperate behavior you've attached: if one event
updates the repeater, the component is not available anymore.

3. to debug: really look closely at the generated behavior URLs and
look closely at the generated IDs to see if they update to another
value than expected

Yeah.. we have a drop down that updates a repeater. The link is inside the 
repeater.
But I'm not sure why the link is getting messed up.
Also, this only effects XP.

Ok. I investigated and we are sub classes DataView, so we should inherit the 
default reuse strategy.
Which is DefaultItemReuseStrategy

Do I still have to explicit set it?

It is still odd to me that this only happens in XP?!

Re: strange error

[Martin Makundi]

I get this quite often on our production site, how can you reproduce
it?  My guess is that it somehow relates to invalid session and
clicking stale links on the page. We get this whenever googlebot or
similar browses our pages.

 The error seems to indicate that the a component is not on the page when it 
 is visible on the page.
 The error is also intermittent.

Re: strange error: getter for member

[Jeremy Thomerson]

Please show the code where you use either a PropertyModel or a
CompoundPropertyModel - that's what is causing this.  Wicket is trying to
find the getArtikel() method on your Artikel class.

It sounds like your Form has a CompoundPropertyModel bound
to ad Artikel instance and a DropDownChoice (or something 
like that) with id artikel and without its own model. Then
CompoundPropertyModel binds it to the property 
Artikel.artikel -- see the Models page on Wicket wiki for
details.

As others pointed out, with your code it's easier for us to
see what's going on.

Problems like this are fairly common when using
(Compound)PropertyModels, and I've found it good to write
unit tests from early on to catch them soon.

Best wishes,
Timo

Re: Strange Error - ModalWindow from ModalWindow - error when closing

[Artur W.]

More info:

- Error appears only once in a session
- When it appears it never happen again in the same session
- Only appear when the pageMapName was not set for the second ModalWindow

I thought that setPageMapName is not a mandatory, isn't it?
