Martin,

I was not suggesting a permanent change to the framework.  Just temporary
while you debug the problem.  I got the source, did mvn install, it
generated the jar file which I then copied over to my project.  If I can do
it anyone can.  The problem isn't in wicket but in your domain object(s).
I'm out of ideas.  Maybe someone from the wicket team has a good suggestion.
Sorry :-(

 Martin,

 I don't know a good way.

 Do you know what page is causing the problem?  Manually check each object
 in
 all components of the page.

 Once you know the page you can try removing components until the error goes
 away.  Last one removed is the offender.  There may be multiple offenders.

 Maybe not a good way.  Get the source for wicket and modify
 org.apache.wicket.Component.readObject(Component.java:4465) to catch the
 exception.  At this point you can either print the class of the object
 being
 read (some type of Component) or use the debugger (my preference).  You
 might have to back up to org.apache.wicket.protocol.

 http.SecondLevelCacheSessionStore$SecondLevelCachePageMap.readObject(SecondLevelCacheSessionStore.java:417).
 This may be a bit of work and might not tell you anything.  The up side is
 that you now have wicket source and can debug your next problem.  I usually
 assume there will be another problem.

 I'm sure others reading along will have better ideas.

  Hi Martin,

  I'm new to wicket.  Could this have something to do with wicket trying to
  restore a page from serialized data.  If one of the objects on your page
  can
  not be serialized you will get an error when wicket tries to restore the
  page.  I think you might see this when the back button is pressed.  I
 think
  using a detachable model is one option if you use a 3rd party object that
  isn't serializable..  If you wrote the object you can make is
 serializable.
  Then again I could be all wrong.

DataView component path in WicketTester

2010-01-13 Thread Java Programmer

Hello,
Is it possible in WicketTester to check the items which are inside
DataView - an example:

DataView dataView = new DataView (sampleDataView, provider, 10) {
@Override
protected void populateItem(Item sampleItem) {
sampleItem.add(new Label(title, new Model()));
}
}

and in WicketTester I want to:
getWicketTester().assertComponent(sampleDataView: something :title,
DataView.class);

How can I get that 'something' for the test?

Regards,
Adr

Re: page expired problem issue wicket how resolve fix eofexception peekbyte

2010-01-13 Thread kirillkh

Hi Martin,

Some IDEs (NetBeans, for one) allow to place an exception breakpoint, which
means the debugger will pause when certain exception is triggered. You
should try downloading wicket's sources as suggested and placing breakpoint
at EOFException.

SV: Wicket Portlets and Liferay

2010-01-13 Thread Wilhelmsen Tor Iver

We are running Wicket + Liferay (Webspace) in Glassfish 2, and experience no 
problems; IIRC Glassfish uses the same Catalina engine as Tomcat?

 
 For AJAX/resource requests, another supports element for mime-type
 text/xml is needed.

This sounds like a Tomcat issue, our portlets use Ajax fine without such a 
mime-type setting.

 2) Name congruence in deployment descriptors
 
 The name in the pattern under //filter-mapping/url-pattern in web.xml
 (e.g. /testPortlet/*) has to match with the value under
 //portlet/portlet-name in portlet.xml, otherwise the portlet will not
 be
 rendered, or you get StackOverflowExceptions in LR.

Again, possibly a Tomcat issue, in Glassfish we use e.g. a name 
LocalMessagesPortlet with the filter-mapping /localmessages/* with no issues

 The requested resource (/hellowicket-portlet-1.0-
 SNAPSHOT/testPortlet/)
 is not available. instead of the actual portlet content.

I would recommend using a more readable build/finalName pom.xml setting instead 
of the version-appended artifact name unless you want to deploy multiple 
versions.

This is a Liferay issue, they don't support */* so when using ajax you need:

Help with Form submission and Ajax buttons

2010-01-13 Thread Sumit Raja

Hi,

Beginner question with Form handling: I have a panel that accepts name value
pairs in text fields.On the form there is an ajax button to add a value, an
ajax button to remove a value and an actual form submit button. I  have a
onSubmit handler for the form that actually processes the NV pairs once the
user has finished. When either the plus or minus button are pressed I update
the form's model and have the form rerenderd. For this to work correctly I
need the form's model updated but not have the form's onSubmit handler
called.  Setting default form processing to false on the twoajx  buttons did
not work as the model was not updated correctly (NPEs thrown)

I have overridden the two buttons' onSubmit() handler to set a flag (as
these seem to be called before the form's onSubmit()) and check for this
flag in the form's onSubmit and save or ignore the submit accordingly. Is
this the right way to do this?

I don't want to use another button to do the 'true' form submission as I
need to have this panel embedded in a wizard as well as an ordinary page.

Re: Discard queued ajax requests

2010-01-13 Thread Daniel Frisk

Found the answer. If we set the channel name to something that ends  
with |d (pipe d) the channel changes to drop behavior.


Great! (but a bit obscure)

Wicket friends,

another question regarding high latency. Here is the scenario:

* I have a lot of network latency so all ajax requests have  
considerable delay.

* User types in a form that submit itself on every keyup event
* All but the first submit is queued since the ajax channel is busy

Now when the first submit is processed I would like to somehow prune  
the queue so that only the last submit is processed and all other  
submits are discarded. Can this be done?

Hi Martin,

Some IDEs (NetBeans, for one) allow to place an exception breakpoint, which
means the debugger will pause when certain exception is triggered. You
should try downloading wicket's sources as suggested and placing breakpoint
at EOFException.

 Martin,

 I was not suggesting a permanent change to the framework.  Just temporary
 while you debug the problem.  I got the source, did mvn install, it
 generated the jar file which I then copied over to my project.  If I can do
 it anyone can.  The problem isn't in wicket but in your domain object(s).
 I'm out of ideas.  Maybe someone from the wicket team has a good

  Martin,

  I don't know a good way.

  Do you know what page is causing the problem?  Manually check each object
  in
  all components of the page.

  Once you know the page you can try removing components until the error
 goes
  away.  Last one removed is the offender.  There may be multiple
 offenders.

  Maybe not a good way.  Get the source for wicket and modify
  org.apache.wicket.Component.readObject(Component.java:4465) to catch the
  exception.  At this point you can either print the class of the object
  being
  read (some type of Component) or use the debugger (my preference).  You
  might have to back up to org.apache.wicket.protocol.

 http.SecondLevelCacheSessionStore$SecondLevelCachePageMap.readObject(SecondLevelCacheSessionStore.java:417).
  This may be a bit of work and might not tell you anything.  The up side
 is
  that you now have wicket source and can debug your next problem.  I
 usually

   Hi Martin,

   I'm new to wicket.  Could this have something to do with wicket trying
 to
   restore a page from serialized data.  If one of the objects on your

   can
   not be serialized you will get an error when wicket tries to restore
 the

I dont think the exception and page expired things are related if you are 
only getting the exception when the AS starts.
When you stop the AS, it normally tries to serialize active sessions and 
read them back when you start it again to restore.


After stopping server, if you change serialUID of any class that was 
serialized that exception may occur.
Also if you do not shut down server properly, server wont be able to 
serialize everything in a correct way and may not be able to read

back which will again cause this kind of exceptions.

 Martin,

 I was not suggesting a permanent change to the framework.  Just temporary
 while you debug the problem.  I got the source, did mvn install, it
 generated the jar file which I then copied over to my project.  If I can
 do
 it anyone can.  The problem isn't in wicket but in your domain object(s).
 I'm out of ideas.  Maybe someone from the wicket team has a good

Re: Help with Form submission and Ajax buttons

2010-01-13 Thread Stijn Maller

In the form's onSubmit() handler you can use findSubmittingButton() for your
check instead.

2010/1/13 Sumit Raja sumitr...@gmail.com

 Hi,

 Beginner question with Form handling: I have a panel that accepts name
 value
 pairs in text fields.On the form there is an ajax button to add a value, an
 ajax button to remove a value and an actual form submit button. I  have a
 onSubmit handler for the form that actually processes the NV pairs once the
 user has finished. When either the plus or minus button are pressed I
 update
 the form's model and have the form rerenderd. For this to work correctly I
 need the form's model updated but not have the form's onSubmit handler
 called.  Setting default form processing to false on the twoajx  buttons
 did
 not work as the model was not updated correctly (NPEs thrown)

 I have overridden the two buttons' onSubmit() handler to set a flag (as
 these seem to be called before the form's onSubmit()) and check for this
 flag in the form's onSubmit and save or ignore the submit accordingly. Is
 this the right way to do this?

 I don't want to use another button to do the 'true' form submission as I
 need to have this panel embedded in a wizard as well as an ordinary page.

 Thanks

 Sumit

I dont think the exception and page expired things are related if you are
only getting the exception when the AS starts.
When you stop the AS, it normally tries to serialize active sessions and
read them back when you start it again to restore.

After stopping server, if you change serialUID of any class that was
serialized that exception may occur.
Also if you do not shut down server properly, server wont be able to
serialize everything in a correct way and may not be able to read
back which will again cause this kind of exceptions.

AbstractDefaultAjaxBehavior using onComponentRendered rendered many times

2010-01-13 Thread Esteban Masoero


Hi:

Using wicket 1.3.5, I have a 
MyAbstractExtensibleChoiceAutocompleteBehavior (that extends 
AbstractDefaultAjaxBehavior, and I think it is a modification of some 
wicket class) related to the autocomplete feature that inside 
onComponentRendered method does something like:


cResponse.write(JavascriptUtils.SCRIPT_OPEN_TAG);
cResponse.write(var foo = new Wicket.ExtensibleChoiceAutocomplete ...);
cResponse.write(JavascriptUtils.SCRIPT_CLOSE_TAG);

Then I have a MyTextField subclass that adds this behavior to itself 
when it's constructed, so the autocomplete options are shown properly.
MyTextField also adds to itself an 
AjaxFormComponentUpdatingBehavior(onchange) so we can track the 
changes and do some stuff.


So here's the thing, I noticed with firebug that every time I change the 
component's value and the AjaxFormComponentUpdatingBehavior is called, 
MyTextField is refreshed (added to the target) and the 
onComponentRendered method of the other behavior is called, and the js 
tag is added to the one that previously existed. So I have:


script type=text/javascript...//script
script type=text/javascript...//script

...and everytime I change the component's value, one line is added. From 
what I saw in Wicket.ExtensibleChoiceAutocomplete class, It shouldn't 
have negative effects, however, I also think it's not a desired effect.
Can anyone tell me if this is normal or I'm doing something wrong or 
whether I shouldn't worry at all?


Thanks,

Esteban

Re: filter options in available side of palette w/o losing selected options

So I've got it partly working. It works after I submit the form (using
IndicatingAjaxButton). If I filter the available items before submitting,
the selected items are cleared.

Which leads me to the question, what is executed during an onSubmit() that
is not during an OnChangeAjaxBehavior.onUpdate()? I thought the onUpdate
was essentially the same thing as a submit.  

Can anyone tell me why this may be occuring?

I'm using a text field to filter the available options in a palette which i
have working but when the options are filtered the previously selected
options get deleted.


is there any way i can keep the previously selected options in the palette?

wicket security future - contribute!

hi wicket folks,

in my last wicket projects i used wicket-auth roles and swarm/wasp. i think
swarm/wasp is a really good base for larger web-applications. but we all know
about the problem with swarm/wasp. i developed a few extensions for swarm, but
its a lot of code and so nobody starts to maintain and whats more important to 
develop. so wasp swarm stops on wicket 1.3.

there was plans to integrate wicket-security in 1.5. @wicket developers: is this
still relevant?

i think we will not find one person who develops wicket-security allone - so
who's interested?
its not the part brings the most fun in wicket development area but a very very
important part of every enterprise application - so contribute! lets define a
security-subteam.

regards alex

Ajax and form handling and clearInput

Hi,

i use a drop-down to switch some data in view. replace data in my model-bean
class (pojo wraps different business objects) and repaints the form via ajax-on
change event. (data binded via propertymodel)

some fields are required.

1. all fields are valid, works fine
2. clear one field and try to submit - fails. Model is still valid. cool
3. switch the drop down list. model-object will replaced and the form added to
ajaxtarget. expect to see the model value of new model object
4. fails! the field still is empty. why?

public final String getValue()
{
if (NO_RAW_INPUT.equals(rawInput))
{
return getModelValue();
}
else
{
if (getEscapeModelStrings()  rawInput != null)
{
return Strings.escapeMarkup(rawInput).toString();
}
return rawInput;
}
}

input is empty (cleared field before last button submit) , so the geModelValue
isn't called.

Form#clearInput or FormComponent#clearInput helps, but i think i make a mistake.
i can't imagine that ajax-events on failed forms which switch the model and
repaint the form have to clear the form manually.

wicket 1.3.5

regards alex

hi igor,

thanks for really fast reply;-)

i forgot - the css switchs programmatically (for different options, not all). so
static selectors doesn't help

thanks alex

this is by design. formcomponents buffer input that is in error so it
can be redisplayed. you can use either form.clearinput() or for your
usecase a bit more appropriate form.modelchanged() to notify the model
that you have changed the backing model object and it should drop any
buffered state

2010-01-13 Thread Igor Vaynberg

then you are stuck doing what you are doing. you can request for some
methods to be added into ichoicerenderer such as getoptgroup() and
getcssclass(). maybe we can do that in 1.5

When I think about it now - you're right. i have to notify the form about
switching their underlying business object

thanks again alex
