Darn it doesn't work. I guess this is a problem with Websphere :(

Thanks for your help though

Enable and Disable using Ajax

[Toscano]

Hello,

I found some questions related to this topic, but I couldn't make it to
work. 
I have two dropdowns, countries and regions. The easy thing is that I load
the regions when the country has been selected, and I use
AjaxFormComponentUpdatingBehavior for this and works.
The thing is that we don't have Regions for all the countries, so in that
cases I want to disable the dropdown.

This is the code I have:


// countryWork is the first dropdown
countryWork.add(new AjaxFormComponentUpdatingBehavior("onchange")
{
protected void onUpdate(AjaxRequestTarget target)
{target.addComponent(regionWork);}
});

// and regionWork is the region

 IModel regionModelChoices = new AbstractReadOnlyModel()
{
public Object getObject(Component component)
{
   if (professionalInfo.getCountryWork()!=null)
 regions =
getRegionDaoInterface().getRegions(professionalInfo.getCountryWork().getCountryID());
  if (regions.size()==0)
   regionWork.setEnabled(false);
   else
   regionWork.setEnabled(true);
   return regions;
}
};

  regionWork  = new DropDownChoice("regionWork", new Model(),
regionModelChoices,
  new ChoiceRenderer("regionName", "regionID"));
  regionWork.setOutputMarkupId(true);

The dropdown changes, but with one refresh delay. For example, I have
regions for Canada but not for Spain. If I change to Canada, nothing
happens, but the next change in the country will enable the dropdown.

Any ideas?

Thank you very much for your time,
Oskar

How Wicket Ajax?

[Pen]

We are using the Wicket as our MVC framework. I have read wicket has a very
good Ajax support . I am newbie. Does anybody know how to use it with jquery
and json with wicket.
Here is an example Jquery grid example and json, but the server side code is
in PHP, how to do it in wicket

http://trirand.com/jqgrid/jqgrid.html

Any sample example will be greatly appreciated.

Re: Can wicket handle events generated from javascript created?

[Igor Vaynberg]

there is no magic here. look at how Link#getURL() works - it generates
a url that invokes onLinkClicked on that Link component. you can use
much the same mechanism and pass that url to your javascript.

Page Expired issue

[Joshua Jackson]

Dear all,

What is the workaround so my request is not expired?
I got this exception when clicking the Link component not long after
the application is loaded:
--

Page Expired

The page you requested has expired.

Return to home page
---

This apps is deployed on IBM WAS 5.1 and I already set my appserver so
the session would not expired. It would be ridicuolus if my page is
expired not long before my apps is loaded.

Can anyone give me a direction regarding this?

Thanks in advance

Can wicket handle events generated from javascript created?

[dd du]

Hi, all,
I am new to wicket, I have a question about calling javascript from wicket,
suppose I create a page from wicket, from this page I click a button, which
wicket will call a javascript function, this function will create a dialog
window with fancy GUI controls, from these controls, if I click one of them,
an event handler from that javascript file will be called, inside this
handler, I need to call back to a wicket java method to handle business
logic, now how can I do that? I know if wicket creates all the GUI controls,
wicket can handle the events easily, but I want javascript to create them
since it deals with fancy style sheets.

Is there a way wicket can handle events generated from javascript created
buttons? or a way calling back to wicket java code from javascript code?

Thanks

Thats pretty much it.

I had a date member of my bean and was using a text field to set it on

because I didn't have a feedback panel, I couldn't see it (and nothing was
coming out in the log).

Re: Is it possible to get AjaxLink stateless?

[Chris Lintz]

Ok that makes sense.  To me i can chalk this up as one thing in the framework
that would be a real joy to fix - that being having AjaxLink or other
related Ajax components stateless.  I think its a real down fall that
sessions are created (and hence Page store cache files) for an Ajax link. 

On a really high traffic site that uses clustered session replication, there
are affects on the back end from generating all of these sessions just for a
link.  Part of my current tasks are trying to minimize session creation.

Re: facebook support

[Chris Lintz]

I am curious what type of Wicket components/functionality you are hoping for?

Just on a side note, we are using Octazen - http://www.octazen.com/ for
social network slurping of contacts, etc.  Of course there is a small
license fee for the product, so it would be ideal to have a free library to
work with.

Doing something on Shift+Click

[vr . sundar]

Hi,

I have to activate a hidden option when a user shift+clicks something.
 How do I go about doing this? From reading the docs, the idea I
currently have is this: Add a new behavior that extends
AjaxEventBehavior for the onClick event.This behavior should
contribute some javascript that is used on the onClick event. Add this
new js function to the event processing using the IAjaxCallDecorator
interface. This js function will check if event.shiftKey is true. If
so, do the usual wicketAjaxGet otherwise do nothing.

Is this doable? Am I on the right track or is there some simpler way.
Any suggestions greatly appreciated. My other option is to have a
hidden link with an accessKey that I can use to get the job done. But
from what i read accessKey seems to work differently on diff browsers
and OS.

thanks
sundar

Re: Is it possible to get AjaxLink stateless?

[Johan Compagner]

no because the ajax behaviors are also not stateless.
So even if you make the link stateless then the behaviors it has make them
statefull again.

Sometimes ajax things can be stateless but i still think it is a bit strange
for 90% or more of the cases
Why is the link an ajax link?. Because in my eyes if you use ajax you still
use the old page
and the ajax call just updates parts of the page. But if you do that. Then
ajax can't be that easy
stateless because how are you going to make exactly the same state as the
client sees in the browser
for the next click?

And ajax clicks should be lean and mean in my eyes because they should be
fast and could happen frequently
and creating constantly a page for that is pretty heavy.

We (Teachscape) had a couple of occasions where it seems we didn't get
notifications of expired sessions (using Jetty btw). So it may very
well be a bug. Unfortunately one that is hard to trace.

The way to go then would be to work with a proper HttpSessionListener
and HttpSessionActivationListener. That should cover both expiries and
passivate/ activates.

Re: How To Change Page Store Size in DiskPageStore?

[Matej Knopp]

Yeah, something like this could be done, but then we would probably
have to user separate folder for each pagestore / application, just to
make sure that one page store doesn't touch other pagestore files.

Still, the question is whether we should do this at all. If you kill
your container (don't bring it down the regular way), shouldn't you be
also responsible for cleaning the temp folder?

If the sessions are picked up again after a restart, I agree we

Re: WicketNotSerializableException withi FileUpload

[Johan Compagner]

Ok the problem is that somehow you are holding on to a FileUpload in your
page
And those are not meant to be kept over requests.

it seems that you keep it if i read it right in a normal Model:

[class=org.apache.wicket.model.Model]
   private java.io.Serializable
org.apache.wicket.model.Model.object
[class=org.apache.wicket.markup.html.form.upload.FileUpload]

How do you create the FileUploadField?

I guess with a normal new Model()?

I think we need to fix that somehow in the detach of the FUF because if the
model is set
we should look into the model and if it is a FileUpload get rid of it or
something.

Re: How To Change Page Store Size in DiskPageStore?

[Chris Lintz]

We get dangling cache files.  I have the sessions set to expire in 1 hour.  I
check one of my servers and i see cache files from over a week old.  This
could of only have occurred because of the multiple restarts.  Maybe its a
bad timing where the HttpSessionBindingListener does not receive a
notification.  

I figured the DiskPageStore probably kept a map of cache files.  I those
references were kept in memory, there be a separate thread that runs and
grabs all file cache names in the file store (basically the JSESSIONIDs) and
compare that to the references in the map to see what is a valid cache file. 
I suppose my assumptions are wrong.

But should we really do that? When session timeouts, the data is
deleted anyway. These "dangling" files seem to be a caused by
something else.

No, as sometimes you actually want to resume those sessions.

I guess this is more  shell type of thing rather than somethign Wicket
can take care off. At least, as long as there is no bug in cleaning
the stuff up when sessions expire.

No we can't do that, If you as you should terminate your web container
gracefully
then the web container will save all the sessions to disk. Then if you
restart it again
all the sessions are loaded again. And yes the application works just as
it was never
restarted. But if we throw away all the page stores. Then we loose all the
data
of sessions that are currently active.

The only thing i can think of is having some check that only deletes things
that are not touched for X hours or days.

Re: Disabling serialization/storage of pages in session?

[Johan Compagner]

Use detachable models.. Never keep database data live inside your models
just store the minimal state so that you can construct it again.

The DiskStore is for the backbutton and the PageMap (thats in the session)
is for the
current page. And as long as that page is statefull you have to store it in
the session
There is no other way because that wouldn't make any sense.

and which are dangling??
How do you know that? If i stop tomcat (even in development mode)
and i restart again nothing is dangling!! All the session are still there
and are still
using the page store.

And from top of my head there is no api to get all the current session id's
from
an instance when the instance does start up..

So as long as we can't do that, we can't delete files because we have no
idea if the sessions are really gone or not.
I guess a seperate cron job can clean up the files in that dir if they are
really old?

Is it possible to get AjaxLink stateless?

[Chris Lintz]

Hi.  So i have tried setting the stateless hint and my AjaxLink is still
statefull.  I read some where where even Ajax components can be stateless. 
What am I missing?

AjaxLink addFriend = new AjaxLink("addFriend")
{
@Override
protected boolean getStatelessHint() 
{
return true;
}

private static final long serialVersionUID = 1L;

public void onClick(AjaxRequestTarget request)
{
makeFriends(sessionUserName, profileUserName);
}
}

Well, think about the implication of that limit: you basically limit
the number of concurrent sessions you can handle. Your servlet
container/ load balancer would be a better place to impose things like
that.

Do you really have a limit on how many files can be created? You
typically want to limit the number of active file handles at any given
time, and I think that is already part of the package. To limit the
number of files/ directories strikes me as on odd thing to want.

Ok here is a bit more clarity after digging further.  Timed out sessions do
trigger a removal of the of the PageStore file.  However if Tomcat is
restarted there is no cleanup of the PageStore files on disk.  In other
words the Page Store will leak those cache files and never clean them up.

Re: How To Change Page Store Size in DiskPageStore?

How can we limit the number of files and/or directories?  I only see the
option to limit the size of the session or the size of the pagemap for the
DiskPageStore ( DiskPageStore(java.io.File fileStoreFolder, int
maxSizePerPagemap, int maxSizePerSession, int fileChannelPoolCapacity)

That would be magic!

While we're at this epic moment after spending days thrashing this out
could we spend just 3 extra minutes to investigate implementing standard
Java method like behavior for this feature?
Ie., In the case that no override  is provided in a derived
page, simply use the markup in the  tag in the base page.

Then it would work like methods work in Java - and it's probably how
most Java developers would naturally expect an OO framework like wicket
to work anyway.

Intuitively it seems like an easy to implement option in the framework:
the / feature is already merging code from the base page
anyway - if there is no override  tag in a derived page then it
simply pulls the markup from the base page's  tag.

The only way to do that is to create an images package, put some dummy
class in there, and use that as the reference when you these
resources.

Re: packaging images/css in a jar?

[mfs]

Eelco,

I really appreciate your quick follow-up..thats whats great about this
community..and one of my convincing arguments..

Anyways actually i dont have a webapp directory and dont want to have that
in my jar project...just want the .class files and the images (and may be
css)..both residing it a different folders structure...
basically below is the resulting jar structure i have and would want to keep

my-custom-component
- [package/classes] : org/xyz/utils (contains the page components and other
classes)
- [images/css] : images/myimage.jpg, css/style.css

Not with my impl.  In the case of a chained model, the wrapped model is
inserted into the chain in the place of the model it is wrapping.  So that
sort will still occur, but it will get it's list from the wrapped model.

I posted some of the files on another message in this thread.

In that order the list would be sorting PRIOR to appending the item, which
could result in an unsorted list.  In the order I specified, the item would
get appeneded and then the sort would take place.

I don't have time right now to make a sample app, but this should be enough

But it is really premature optimization to worry about this now. If
you are worried about this, the best thing you can do is write an
actual page (or a couple) and load test it and see how it behaves.
Much better than wild guessing what you think might happen :-)

Only the current page yes. Unless you work with stateless pages, which
don't get stored it the first place.

For images residing in your web app directory, you would use for
instance new ContextImage("img", new
Model("images/company-logo.jpg")); or simply

Well that was just hypothetically speaking..what i meant was it would have
loads of data loaded in it..so it was that scenario where i was wondering
that we shouldnt store the state of each page.
Yes as you pointed out using detachable models can certainly be one to way
to go..but at the same time since i am sort of presenting my company with
all the features, i want to be prepared with answers and would want to know
as much as i can..

So with what i understand the page serialization can be disabled by
providing a dummy page-store but the storage of pages in the pageMap and
hence in the current active session is something which is implicit and not
something we can avoid..

You could use Wicket resources for this. But you don't have to use
Wicket for everything you do either; if it is simpler to use a plain
servlet for this, that's fine.

Re: packaging images/css in a jar?

[mfs]

Actually it does work when the image is in the same directory as that of the
page (same with the example u pointed out)..how would i refer to an image
which is altogether is a different structure...

lets say my page is at org.xyz.util [page.html] and from within it i want to
refer to an image which is in the images directory...

using 

add(new Image("taxCientLogo", new Model("images/company-logo.jpg")));
add(new Image("taxCientLogo", new Model("/images/company-logo.jpg")));

makes it look inside util and appends the above path..

RE: Wicket & Servlet Filters

[William Hoover]

It's not for authorization... It's for running reports. I realize that the 
Wicket stratagy is to work with components, but in this instance its not a 
practical option. The business requirement dictates that from any page in the 
application a parameter can be added to the url (by means of external systems) 
that will route the application (Wicket) to the appropriate page for 
processing. I'm over simplifying the scenario, but that is the jist of it.

I hope to convert this process to a webservice to be consumed by the internal 
Wicket application in the near future, but there are some dependencies with 
some of the external applications that prevent us from doing so at this time.

Try to forget how other frameworks do things and look for solutions on

For what purpose? If it is for authorization, we have authorization
strategies: see wicket-auth for an example project. Furthermore, you
would not be checking for a parameter since the idea with using Wicket
is that you work with components/ objects, not request parameters.

Perhaps I didn't get the explanation but why can't you wrap models in this 
order?

AppendingListModel(
SortingModel(
HibernateListModel()
)
)

Re: ResourceReference with locale and style, for CSSs

[German Morales]

Hi,

I use it inside a page.

I've tried...

   // inside the page constructor
   add(HeaderContributor.forCss(new ResourceReference(MyPage.class,
"style.css")));

and

   // inside renderHead
   cResponse.getHeaderResponse().renderCSSReference(new
ResourceReference(MyPage.class, "style.css"));


And I don't want to set the style and locale explicitely. What i want is
to deliver the application to a customer, and, if he wants, he adds the
customized page for a locale or style by itself (he could set the style
with a parameter or whatever). And as far as i understand the wicket
approach, that's how it should work automatically. In fact it works
perfecly when i do it for the html of the same page. The difference is
that the html is handled in other way (the framework does it) and when i
try to do it for the CSS of the page i do it (and it doesn't work). So
there must be something i'm not doing properly.

Or, how should be the way to provide styled CSSs, there is another aproach?

thanks and bye,

German

Wicket reads packaged resources from the classpath, including
individual jars. For instance, look at the date picker in
wicket-datetime. That has a whole bunch of CSS/ JavaScript and even
image dependencies that all get served from the jar.

But I hope you're not storing MBs of data in your pages?! Users will
also get pages served that are MBs large? Note that you don't have to
keep anything in memory if you work with detachable models.

Re: Disabling serialization/storage of pages in session?

[mfs]

Basically we are still researching wicket and figuring out if that would be
the desired framework for us (so far it does look promising)..and in that
context we are exploring all the different
scenarios/use-cases/possibilities...

Now there would be certain use-cases/pages in our application which would
have alot of data in it (lets say in mbs), and in that scenario storing the
entire model-data/components would probably bring in too much of a load on
the system (in my opinion...given high volume of users..) so with that may
be we would not want to store the pages in pageMap at all (which in turn is
stored in the session)..i do understand the back button scenario where we
might think that yeah "we need to have that previous state"
..but lets say what if we dont have that back button as a link (offcouse we
cant avoid the browser-back button where he would be loaded with catch-ed
page)
So its in the above context i had asked about disabling of page/pageMap
storage in session altogether (not just the serialization of old pages)

Try to forget how other frameworks do things and look for solutions on
a case by case basis.

For what purpose? If it is for authorization, we have authorization
strategies: see wicket-auth for an example project. Furthermore, you
would not be checking for a parameter since the idea with using Wicket
is that you work with components/ objects, not request parameters.

How do you use the resource reference? I think the class was designed
in such a way that the components that use it (Image for instance) are
responsible for setting the appropriate locale/ style 'just in time',
so that switching locales etc works.

No, just in the classpath. Look at wicket-examples/ images example for instance.

RE: Wicket & Servlet Filters

[William Hoover]

So in theory it can be accomplished, but is not recommended to do so... What is 
the common practice when dealing with wicket related data in a servlet filter? 
Say you have a simple task of checking for a parameter and/or session object 
and redirecting to specified Wicket pages, accordingly? It doesn't seem natural 
to handle this type of logic outside the scope of the Wicket API. I guess this 
is what I'm attempting to avoid :)

in the wicket world components have overridable listeners for

need different handling. we are not huge fans of these
global/all-penetrating listeners. although in some cases we have done
so, we have a component instantiation listener and a global before
render listener. but so far that is all iirc.

Re: packaging images/css in a jar?

[mfs]

but i am wondering as to how would i make it work wicket such that image gets
fetched from the classpath and not relative to the application root..
So basically here is my scenario, i have jar bundled with the page
components and in them i want to refer to the images (bundled within the jar
only).

This jar will eventually be bundled within a war application which will be
using these components.

That probably wouldn't be very object oriented. Like Igor said, we
have various special global listener constructs, and you can also work
with a custom request cycle to react on the start and ending of a
request.

Do you have a specific use case in mind?

Yeah, we do. We are using one file per pagemap. I believe that the
number of files can be limited as well as the number of directories.
So if you have one directory per session you'll have less entries than
one file per pagemap in one common directory.

As far as I know, we do our best to delete those old sessions.
AbstractHttpSessionStore puts a HttpSessionBindingListener in the
user's http session when it starts so that the gets notified when
DiskPageStore#unbind gets called by the second level cache session
store and that should then take care of removing the files for that
session.

Can you debug why this isn't happening in your case?

Guys I am on the same project so I can speak a bit more.  The real issue is
that on Redhat the default max directories is something like 32K.  We ran
out of file descriptors.  Basically for every unique session there is a
directory created for the second level cache. 

I think the real issue for us is that when a session expires the
corresponding second level cache is not removed from disk.  This seems like
a serious bug to me.  I have yet to see a second level cache be removed
unless a forced session invalidate() occurs. 

Any ideas on how we can get these page store files to be removed when a
session times out?   I have looked at tuning the DiskPageStore, but the
constuctor args dont appear as if they will help the issue:

DiskPageStore(java.io.File fileStoreFolder, int maxSizePerPagemap, int
maxSizePerSession, int fileChannelPoolCapacity)

be added to perform some operations on the event. Just thought it would be 
convenient to do something like this in the Wicket world :)

Re: ResourceReference with locale and style, for CSSs

[German Morales]

Hi johan,

The problem is that the file is there... just that it doesn't seem to be
looking for it.

If i force the full constructor:

new ResourceReference(MyPage.class, "style.css", getLocale(), getStyle())

all works, so the file is correcly found and the name is correct.

The problem is when i don't set the locale and style explicitely (as it is
supposed to be done):

new ResourceReference(MyPage.class, "style.css")

then it doesn't find the file. Actually i think it doesn't even try to
find it, since as i mention i put a breakpoint in
ResourceReference#setStyle() and nobody is calling it. So later internal
code to load the resource uses style and locale with null values.

I'm not sure if there's something i'm missing, or how it is supposed to be
done.

Thanks,

German

RE: Rendering a fieldset class attribute

[William Hoover]

I hear you... read the docs... "addAttributeIfNotPresent" :)

It seems odd that the AttributeModifier is under the org.apache.wicket package, 
but the SimpleAttributeModifier is under the org.apache.wicket.behavior 
package? They both extend AbstractBehavior.

I would have to agree with you... it does seem too broad. One of the aspects of 
Wicket that makes it enjoyable to program in is that they have kept its usage 
very simple!

Well, given the javadoc I told you to read for the second parameter 
there, no. ;-)

It doesn't make much difference which you use.

AbstractBehavior is more direct and concise.

AttributeModifier is named such that people will find it.

I tend to use the former for what you're doing, and the latter if I 
already have a model kicking around.

There's also a SimpleAttributeModifier if you have a simple String, and 
an AttributeAppender if you wish to mess with what's currently there.

IMO, the API here is far too broad - we should just give people 
AbstractBehavior and tell them to get on with it, but hey ho.

Al

Anything similar for spitting something out _after_ the tag that the

Presumably onComponentTagBody doesn't get called because it is not a

Hi Jeremy,

You can try this: in your constructor, instead of the DataTable, create
an EmptyPanel with the same ID. In the onSubmit for your search form,
create the DataTable and use replace() to replace the EmptyPanel.

Hope this helps.

You can add javascript file to the page header like this:
add(HeaderContributor.forJavaScript(MyPage.class, "myscript.js"));

And javascript calls like this:
add(new DataView("boxList", dataProvider)){
protected void populateItem(Item item) {
item.add(new SimpleAttributeModifier("onclick","row_clicked()"));
item.add(new Label("boxID").add(new 
SimpleAttributeModifier("onclick","boxID_clicked()"));
...

No problem, of course!  :-)


I just committed a patch. Could you check if it suits your needs?


The patch adds checks for "isAttached()" in some operations, but not all.
So I was still getting some similar errors, for example in GMap2.addControl
().

I've worked around this so far by applying a patch in GMap2, adding the
middle line:

map = new WebMarkupContainer("map");
map.setMarkupId("gmapInternalMarkupId"); // Work around problem of
non-attached component
map.setOutputMarkupId(true);

While this is a bit of a hack, could the problem be better fixed in a
similar way?  That would avoid having to remember to do the check for every
operation in GMap2.

Also could you check if the codechange in the ManyPanel is asking for
> the same as your code?


Looks like it yes, but as discussed above, it only calls setZoom() and not
all the other operations that may be called on the component before it's
added into the page hierarchy.

Jan

If you look at the code you've written, you've nearly answered your own 
question. ;-)


Don't use the Form's onSubmit().
Just use the Buttons' onSubmit()s instead.

If you want to allow a Button#onSubmit() without the Form validating, 
then you'll need to call setDefaultFormProcessing(false) on it like 
Sebastiaan said.

Re: Several localized buttons in a form

[Sebastiaan van Erk]

You could use Button.setDefaultFormProcessing(false) to turn of form 
validation.


From the javadoc:

/**
 * Sets the defaultFormProcessing property. When false (default is 
true),
 * all validation and form updating is bypassed and the onSubmit method 
of
 * that button is called directly, and the onSubmit method of the parent
 * form is not called. A common use for this is to create a cancel 
button.
 *
 * @param defaultFormProcessing
 *defaultFormProcessing
 * @return This
 */
public final Button setDefaultFormProcessing(boolean 
defaultFormProcessing)

My problem is that when a user click "Cancel", the form still tried to be
submitted (and since some fields are invalid, it writes some garbage to the
Feedbackpanel). However, in markup, my cancel button is not a "submit", but
a simple "button".

How can I put several buttons on a form?

Thank you for your help ;)

Re: Problem closing a ModalWindow when used through an IFrame

[Ville Paasimaa]

I found a possible fix to this problem. If you leave the
window.parent.setTimeout statement off and just call directly
win.current.close the modal window will be closed.
You can test this by changing getCloseJavacript method of the
ModalWindow.java to return this:

   {
return "var win;\n" //
+ "try {\n"
+ " win = window.parent.Wicket.Window;\n"
+ "} catch (ignore) {\n"
+ "}\n"
+ "if (typeof(win) == \"undefined\" ||
typeof(win.current) == \"undefined\") {\n"
+ "  try {\n"
+ " win = window.Wicket.Window;\n"
+ "  } catch (ignore) {\n"
+ "  }\n"
+ "}\n"
+ "if (typeof(win) != \"undefined\" &&
typeof(win.current) != \"undefined\") {\n"
+ " win.current.close();\n"
+ "}";
}

Matej, what is the purpose of the window.parent.setTimeout in the
original code? Why couldn't the closing be done just simply by calling
win.current.close?

Several localized buttons in a form

Wel i use wicket 1.2.6
Sadly it seems to be a browser compatibility issue. Default I use firefox

IE it works as expected.

DataView question, please help, thanks!

[raybristol]

I am using DataView to show a list, in my html page, I got: 


Box ID
Client name
Job profile
Box status
Store Location
Time in prep
Time in scan
Delete


boxID
clientName
JobProfileName
BoxStatus
StoreLocation
PreppedTime
ScannedTime
 Delete 



then in code behind I use protected void populateItem(Item item) to
specified each table cell's data, because I can put any String in td tag so
I can easily put any javascript function call, however, I want to do that
for each row as well, so the tr tag, such as when use click on a row,
something happen, but I can't find where I can put this ability from the
code behind?

Many thanks for your help!

Re: How To Change Page Store Size in DiskPageStore?

[Johan Compagner]

But 50 is nothing (at least i think it is nothing) and linux should be able

Can somebody peak how many handles we take on those session files? Maybe we
leak somewhere
or do take more then we think.

yeah there is already a call happening to the server. But maybe this is a

Re: Disabling serialization/storage of pages in session?

[Johan Compagner]

like eelco said if you don't want to serialize and store on disk, create a
filestore that does nothing
(or holds a few pages for per session in mem for backbutton)

But what do you mean with disable the storage of pages in a session?
You don't want to store a statefull page at all in the pagemap (and thats
then in the session)?
Because thats really no use at all then because the page in the browser is
useless
If you don't want pages in the session and on disk. Then make them fully
stateless (see stateless link and form)
