Re: [Wicket-user] IDataProvider.size()
Why would want to cache the result? Look, you have to make a decission. Are you interested in paging lists or not? If you are, you should do a count query to determine how many rows there are, and then just load the page of results you need with another one. If you don't want to use paging, but you want to display the whole result set at once, Timo's answer will work fine. what happened if the results returned are big If the results can be big, use a pageable list. It's the whole point of the constructs we have that these components will load just what is needed instead of all the results.

Re: [Wicket-user] IDataProvider.size()
you can only do onDetach on the AbstractDetachableReadOnlyModel, but you
can't do it in IDataProvider if you are to cache the result. Even if you
nullify the object in onDetach, the result list still appear in
IDataProvider. How to nullify the result in IDataProvider?
Jeremy Thomerson-2 wrote:
I believe that the onDetach() { result = null; } should take care of that.
At the end of the request, that will be called and your cache will be
blown away, which means you are as safe as any other way (memory wise),
because the data is only held for the length of the request.
You can verify, but I don't think memory will be an issue there.

You shouldn't. It might not give you problems right now, but you break
the contract with the interface.
You can cache the result so that you do only one query per request to
get both the result size and the result values. Use onDetach to clear
the cache after each request.
It should look like this (pseudo-code):
private List result;
void onDetach() {
result = null;
}
Iterator iterator(from, to) {
return getData().iterator();
}
int size() {
return result.size();
}
private Collection getData() {
if (result == null) {
result = dbquery(from, to);
}
return result;
}

Re: [Wicket-user] ?Contract for Iterator IDataProvider.iterator(int first, int count) ???
in my experience this wont cause a problem. any reasonable db keeps a count of the total rows in any given table. the size() query is most likely select count(*) from foo, which will use that stored count. and even if there is something more dynamic to it, the db will most likely put that statement in a cache and use that. so basically, dont cry wolf until you actually encounter the problem. you can play what-if for a long time :) -igor On 6/10/07, Lec [EMAIL PROTECTED] wrote: Igor, if calling paging 1,2,3 n each time requires a call to iterator(first, count) and size(), which means a call to db, wouldn't this way, it ll give a bottleneck at the database layer?

Re: [Wicket-user] IDataProvider.size()
Eelco,
What i mean is that, you don't necessary have to cache the result
just do the paging lists. you can directly call the db to query the page
just like that...
void iterator( int first, int count)
{
db.getPage( parameter, first, count ).iterator();
}
int size()
{
db.getPageCount( parameter );
}
This approach make heavy db call. Imagine there are 5000 concurrent users
making the same paging, with no constant data changing at the backend (
adding or deletion of data ), then the db will be heavy-loaded with
unnecessary duplication db call - size(). And I realise this is not an
efficient way of pagination, is it?
To avoid this problem, you suggested to cache the results or even the result
size, so that subsequently paging call will not trigger the same
db.getPageCount( parameter ) or even the db.getPage( parameter, first, count
).iterator(); Having said that, however, if you look at it, you will
realise caching is also not an efficient way of doing a paging list,
considering all the records returned might be a potential big record. And if
these records are stored in a List, the memory of the server will be eaten
away especially when the paging site is heavy loaded with concurrent users,
say 5000 concurrent users are doing the same paging. get me? :)
so what s the most optimized way of doing paging using the IDataProvider?

Re: [Wicket-user] IDataProvider.size()
If it's only the repeated execution of a count projection that bothers
you, what Eelco suggest is likely not caching the data returned by the
iterator, it's caching the long returned by size(). It will decrease the
accuracy of the pager in favor of performance, and will not contribute
to significant increase in memory use.
The interface to IDataProvider does require you to provide a size, but
it puts no limitation on how you retrieve that size. If you can
construct a query to return the size alongside your resultset, or your
datalayer otherwise can provide the count baed on the data query alone,
by all means, use it.
If what you want is a pager that doesn't care about the count, implement
it, either as a separate dataTable-esque component, or by modifying the
existing one (which I suspect might even get included, if it leave the
existing implementaiton compatible with existing users of it)

That said, I agreed with the reasoning of most other reactions. It was far from being my intention to start any kind of flame-war. On the contrary I was just sad that my team had not decided to go with wicket , and as Eelco said I thought it was good to let the wicket community know what had happened... feedback is always better then none. I did not take any of the comments posted back badly. I have nothing but respect for Wicket and it's community.

Re: [Wicket-user] ?Contract for IteratorIDataProvider.iterator(int first, int count) ???
yeah i sincerely believe issuing a row count() is an expensive, especially when the row count doesn't change at all Roger Hand wrote: any reasonable db keeps a count of the total rows in any given table. the size() query is most likely select count(*) from foo Then I guess Postgres (up until version 8.0 anyway) is not a reasonable database. Unfortunately, getting a row count is typically an expensive process due to its implementation of MVCC architecture. -Roger From: Igor Vaynberg [mailto:[EMAIL PROTECTED] Sent: Sunday, June 10, 2007 11:38 PM To: wicket-user@lists.sourceforge.net Subject: Re: [Wicket-user] ?Contract for IteratorIDataProvider.iterator(int first, int count) ??? in my experience this wont cause a problem. any reasonable db keeps a count of the total rows in any given table. the size() query is most likely select count(*) from foo, which will use that stored count. and even if there is something more dynamic to it, the db will most likely put that statement in a cache and use that. so basically, dont cry wolf until you actually encounter the problem. you can play what-if for a long time :) -igor On 6/10/07, Lec [EMAIL PROTECTED] wrote: Igor, if calling paging 1,2,3 n each time requires a call to iterator(first, count) and size(), which means a call to db, wouldn't this way, it ll give a bottleneck at the database layer?

My database query is parameterized based on page-component model values, and these may change with each rendering. My problem is that when one rendering presents a short data set, on the next rendering the DataTable is not always requesting all of the rows. The count seems to be affected by the number of rows returned by the previous rendering. I suspect this is because my implementation of int DataProvider.size() assumes that it will be called _*after*_ Iterator iterate(first, count) pulls down the data - so it's always one rendering behind. Should I give the int IDataProvider.size() method the responsibility for figuring out the query string and going to the database?

Re: [Wicket-user] [GMAP contrib] IE7 Ajax target appendJavascript not working?
Yes i'll try to explain in greater detail.
Looks like it was not the appendjavascript that wasnt working. But
something else.:)
Our hidden variables arent updated when using IE. Why they arent updated
correctly puzzles me, because just before the ajax call they seem to
have the correct values.
heres a snip of what I try to do(working everywhere but IE):
GEvent.addListener(googleMap, dragend, function () {
var center = googleMap.getCenter();
var sW = googleMap.getBounds().getSouthWest();
var nE = googleMap.getBounds().getNorthEast();
document.getElementById(latitudeCenter).value=center.lat();
document.getElementById(longitudeCenter).value=center.lng();
document.getElementById(latitudeSW).value=sW.lat();
document.getElementById(longitudeSW).value=sW.lng();
document.getElementById(latitudeNE).value=nE.lat();
document.getElementById(longitudeNE).value=nE.lng();
document.getElementById(zoomLevel).value=googleMap.getZoom();
document.getElementById(gmap_ajaxGMapUpdatingFormSubmit).onclick();
});
So the different variables are stored in hidden fields. Just before the
last entry above, every value looks ok.
Here are some of the java server side code:
Form gMapUpdatingForm = new Form(gmapUpdatingForm);
gMapUpdatingForm.setOutputMarkupId(true);
gMapUpdatingForm.add(new HiddenField(latitudeCenter, new
PropertyModel(gMap.getCenter(),
latitude))
{
public IConverter getConverter()
{
return getUSConverter();
}
});
gMapUpdatingForm.add(new HiddenField(longitudeCenter, new
PropertyModel(gMap.getCenter(),
longitude))
{
public IConverter getConverter()
{
return getUSConverter();
}
});
Please remember that it is actually working in both FF and safari. Ajax
calls goes through as it should, values arent updated.

[Wicket-user] Cyclic parent/child relationship
Hello, I made an innocent programming error that day by adding a Form as a child component of a TextField thats already the child of the Form. In that case, execution gets stuck in an infinite loop in Component.findParent(final Class c). I still am only scratching the surface of wicket, but are there any cases when two component can be parents of each other, as in, is this the case with some component types? Could a check be added in the code to prevent adding a component, if the component being added is already the parent of 'this' component? Or should I just ensure I have enough caffeine in my system before I start putting together component hierarchies ? :) Thanks - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [Wicket-user] [GMAP contrib] IE7 Ajax target appendJavascript not working?
Hi Matej
Currently gmap contrib are using wicket 1.2.6. And currently im testing
with IE 6 which has the problems I mentioned, the ajax calls seems to
yield no problems so far I can see we get a call when the form are
submitted and it calls back after processing. However form values arent
updated, im not sure if that has anything to do with the ajax part?
Im not sure how far we are in the process of upgrading the gmap contrib
to 1.3.

Re: [Wicket-user] [GMAP contrib] IE7 Ajax target appendJavascript not working?
In addition to the previous mail I would like to add, that we would like
to resolve this using wicket 1.2.6.
Now if anything are unclear or so please write and I'll try to explain
further.
Also the current version are the one available from SVN, I belive Iulian
upgraded the example so that its now using that aswell. So you can just
check out the code from wicket stuff repo if you want to see the code..

Hi Matej
Currently gmap contrib are using wicket 1.2.6. And currently im testing
with IE 6 which has the problems I mentioned, the ajax calls seems to
yield no problems so far I can see we get a call when the form are
submitted and it calls back after processing. However form values arent
updated, im not sure if that has anything to do with the ajax part?
Im not sure how far we are in the process of upgrading the gmap contrib
to 1.3.

Our hidden variables arent updated when using IE. Why they arent updated
correctly puzzles me, because just before the ajax call they seem to
have the correct values.
heres a snip of what I try to do(working everywhere but IE):
GEvent.addListener(googleMap, dragend, function () {
var center = googleMap.getCenter();
var sW = googleMap.getBounds().getSouthWest();
var nE = googleMap.getBounds().getNorthEast();
document.getElementById(latitudeCenter).value=center.lat();
document.getElementById(longitudeCenter).value=center.lng();
document.getElementById(latitudeSW).value=sW.lat();
document.getElementById(longitudeSW).value=sW.lng();
document.getElementById(latitudeNE).value=nE.lat();
document.getElementById(longitudeNE).value=nE.lng();
document.getElementById(zoomLevel).value=googleMap.getZoom();
document.getElementById(gmap_ajaxGMapUpdatingFormSubmit).onclick();
});
So the different variables are stored in hidden fields. Just before the
last entry above, every value looks ok.
Here are some of the java server side code:
Form gMapUpdatingForm = new Form(gmapUpdatingForm);
gMapUpdatingForm.setOutputMarkupId(true);
gMapUpdatingForm.add(new HiddenField(latitudeCenter, new
PropertyModel(gMap.getCenter(),
latitude))
{
public IConverter getConverter()
{
return getUSConverter();
}
});
gMapUpdatingForm.add(new HiddenField(longitudeCenter, new
PropertyModel(gMap.getCenter(),
longitude))
{
public IConverter getConverter()
{
return getUSConverter();
}
});
Please remember that it is actually working in both FF and safari. Ajax
calls goes through as it should, values arent updated.

No I dont... It's pretty strange I guess it could be caused by IE not
accepting cookies? And then web container trying with url rewrite.
The difference in the action being called was a matter of me pasting
from two different places, I guess the heat are getting to me now(its
pretty hot here in dk)..

Re: [Wicket-user] [GMAP contrib] IE7 Ajax target appendJavascript not working?
Looking at the the post (I use paros as proxy), things are alright.
Im now suspecting that its our function that aren't merged correctly. We
have a function called refreshGmap which we replace on ajax calls and
then evaluate on the client, im not sure if this are updated correctly
in IE.
The error I get are that the map wont go to the place where the user
draged it, now when we intialize the gmap I in my example set the center
to 0,0 and there it stays not matter what in IE. However it looks as
everything are updated correctly. But the map keeps it center to 0,0
which makes me belive that the refreshGmap function arent updated correctly.
So I guess it could be related to what you talked about in the first
instance?

If you want some advice, I would suggest not using a
pageablelistview
and not keeping your search results as an instance member (unless
they
are very expensive to create). Instead, look into using
DefaultDataTable or extending DataTable. That way you can put all
your

and
retrieve only the results you will display in the current page,
and
not carry them around in the session after the request is over.
Hope
this helps.

yeah i sincerely believe issuing a row count() is an expensive, especially when the row count doesn't change at all Like it is said in the other thread, you should then look at caching the count in either the data provider or the, if the data provider calls a service to get the count, in the service. If you do the latter, you'll cache one long for your whole application, so that won't be a memory hog.

Re: [Wicket-user] IDataProvider.size()
Lec wrote: so what s the most optimized way of doing paging using the IDataProvider? There is no optimal way. You have to engage your brain and make trade-offs, just like you do with everything else. You can make sure your database is configured to cache the COUNT(*) query, which will be as efficient as you need, I imagine. It will probably also stop you getting stale values, depending how your database vendor handles things. However, even if it caches it, you need to roundtrip to your database to find it, which you may consider sub-optimal. To avoid this, you can cache the result of COUNT(*) in your DAO layer for some time (a few seconds or a minute, say). You then need to decide how to cope with stale values. You can cache the result of COUNT(*) in your DAO layer and make that layer intelligently expunge the cache when you run DELETE or INSERT statements, but that assumes nothing external to your DAO layer will be touching the database and that you're not clustering your application. You can make the above cluster-safe by mixing in JGroups or JMS or something else that can send clustered cache invalidations around the place, but you still have external modification issues. You can combine the above with cache timeouts to give you a blend of both, and tune the rate of invalidation messages (you could group multiple entity invalidations into a single message) and also tune the timeout values to give an acceptable trade-off between data staleness and speed. This trade-off will be different depending on lots of factors, including what sort of data you're displaying, how big a performance bottleneck this really is (ideally you want realtime updates, so have you profiled it to make sure you really need to cache things and serve potentially stale data yet?). See, there is no optimal way. If the above confuses you, just do what 99% of people will do, and rely on your MySQL or whatever to cache the value for you and don't worry about it. If you're really concerned, you can profile your application and fix the bottlenecks. They probably won't be where you think they will. Premature optimisation is the root of all evil.

[Wicket-user] TabbedPanel and i18n
Hello,
The application I am working on uses i18n. Wicket has been great with this.
:)
Our base page that every other page extends from, does the following:
getSession().setLocale(((INLWebSession)getSession()).getCredentials((WebRequest)getRequest()).getPreferredLocale());
to set the current locale based on the users preference. The content of the
application is in an iframe. (The wicket pages are in the iframe) The
navigation, preferences elements, etc. are outside the iframe in what we
refer to as the wrapper. Changing the language is done through this wrapper.
When the display language is changed, we refresh the contents of the iframe
and it comes back in the new language.
HOWEVER
We have one page that uses TabbedPanel with two tabs. This page (and tabs)
correctly internationalizes based on the locale used when the page is
loaded. Changing the language in the wrapper does cause the page to refresh,
but not cause it to change languages.
Is there something special with tabs and TabbedPanel?
Another issue with the same page, we use the following constructors:
public ReviewPage(String ahId) {
build(ahId, 0);
}
public ReviewPage(String ahId, int tab) {
build(ahId, tab);
}
So, if no tab number is passed in it uses tab 0. From tab 1, there are
actions that update the underlying object and use:
setResponsePage(new ReviewPage(req.getReqId(), 1) );
to show the changes, effectively just calling it's self. This work just
fine.
However, from a different wicket page trying to have a link that uses the
setResponsePage(new ReviewPage(req.getReqId(), 1) ); causes a
NotSerializableException. Why / how does the same call cause two different
results?
Thanks for any insights.

Re: [Wicket-user] Prototype scoped Spring beans
I read on the wiki that serializing spring beans is a problem because
of injected references. So what I want is something from spring which
it probably cannot give me. But I will try to clear this up on the
spring forum.
2007/6/7, Igor Vaynberg [EMAIL PROTECTED]:
hrm. you say you will have a serialization problem if you lookup the bean
directly and hold on to it. but isnt that exactly what you want? to pull out
a prototype bean and keep it inside the form's scope? the form is in
httpsession and so the bean will be serialized. so if that is what you want
to do you have to make sure the bean is serializable and do the lookup
yourself.
we can probably add @SpringBean(transient=false) or something like that to
keep the reference instead of discarding it, but that wont solve your
serialization problem, it will just save you doing the lookup yourself.
so what exactly do you want?

I put a breakpoint in the constructor of my Form, which has the
@SpringBean annotation on ia property named logic.
Before the super() call, logic is null.
After that, it is set to $Proxy39, with a h-attribute to a

property of the handler is null.
After the next line, where I call a method from logic, the target
property is set to the bean instance.
So it seems that the reference gets lost in the first call.
But, as you said that the bean is transient anyway, I think that
prototype beans could not be used that way for holding state of wicket
components, because that state should certainly also be kept when
using the back button.
I'm not sure what is best then. I could get a reference to the spring
bean directly from ApplicationContext, and just keep it. But then I
would face the problem of serialization.
The best thing would be IMHO if the proxy could somehow do an
automatic re-lookup from Spring for prototype beans, so that not a new
instance is fetched from the container, but the same as before. But I
don't know enough about Spring to say if that is even possible.
2007/6/3, Eelco Hillenius [EMAIL PROTECTED]:
I'm not that familiar with the code, but the interesting thing is that
LazyInitProxyFactory$JdkHandler does cache the bean it located:
if (target == null)
{
target = locator.locateProxyTarget();
}
return proxy.invoke(target, args);
The target is a transient member of JdkHandler and judging from the
code, once the bean is located it should just be reused until the page
is serialized/ deserialized (for backbutton support or when
clustered).
Can you use you debugger to find out what exactly happens?

Re: [Wicket-user] TabbedPanel and i18n
how are you creating your itab/abstracttab objects? can we see that code?
mainly what model do you pass in for the title.
and what object does it say is not serializable?

Hello,
The application I am working on uses i18n. Wicket has been great with
this. :)
Our base page that every other page extends from, does the following:
getSession().setLocale(((INLWebSession)getSession()).getCredentials((WebRequest)getRequest()).getPreferredLocale());
to set the current locale based on the users preference. The content of
the application is in an iframe. (The wicket pages are in the iframe) The
navigation, preferences elements, etc. are outside the iframe in what we
refer to as the wrapper. Changing the language is done through this wrapper.
When the display language is changed, we refresh the contents of the iframe
and it comes back in the new language.
HOWEVER
We have one page that uses TabbedPanel with two tabs. This page (and tabs)
correctly internationalizes based on the locale used when the page is
loaded. Changing the language in the wrapper does cause the page to refresh,
but not cause it to change languages.
Is there something special with tabs and TabbedPanel?
Another issue with the same page, we use the following constructors:
public ReviewPage(String ahId) {
build(ahId, 0);
}
public ReviewPage(String ahId, int tab) {
build(ahId, tab);
}
So, if no tab number is passed in it uses tab 0. From tab 1, there are
actions that update the underlying object and use:
setResponsePage(new ReviewPage(req.getReqId(), 1) );
to show the changes, effectively just calling it's self. This work just
fine.
However, from a different wicket page trying to have a link that uses the
setResponsePage(new ReviewPage( req.getReqId(), 1) ); causes a
NotSerializableException. Why / how does the same call cause two different
results?
Thanks for any insights.

The spring service is what it is complaining about not being serializable.

UserPrivileges userPrivs = creds.getPrivileges();

To be specific my WebSession subclass has a getUser() method. This
user is stored as the session variable user.
Note that (Web)Session is an abstraction. If your session store backs
on HttpSession (like the default implementation does), you can provide
your own session object, and let that call super.get/setAttribute.
public class MySession extends WebSession {
...
public User getUser() {
return (User)getAttribute(my.user.key);

[Wicket-user] Howto determine what objects are part of session state
Through the use of anonymous inner classes it is easy for objects to become part of session state unintentionally. Does anyone know of a tool (or io util package) that would help debuging these issues? Specifically it would be great to be able to print the heiarchy/containment structure of a serialized object so that at any level deep you can see the path that lead to that object becoming serialized. Eelco created something very similar to this to make serialization error messages more friendly, perhaps it can be modified to help with session debuging?

Re: [Wicket-user] Howto determine what objects are part of session state
Through the use of anonymous inner classes it is easy for objects to become part of session state unintentionally. Does anyone know of a tool (or io util package) that would help debuging these issues? Specifically it would be great to be able to print the heiarchy/containment structure of a serialized object so that at any level deep you can see the path that lead to that object becoming serialized. Eelco created something very similar to this to make serialization error messages more friendly, perhaps it can be modified to help with session debuging?

Re: [Wicket-user] Howto determine what objects are part of session state
I just found terracotta provides a nice dump of an object graph if it finds problems in your clustering configuration. This should work for me however if it does not I will definitely take a look at the code you wrote to create a wicket session debug tool. Either way I will open a jira issue.

Re: [Wicket-user] Howto determine what objects are part of session state
yeah, this would be particularly neat if it could tell you the size of each object in the graph using that JMX sizeof call. it's actually the non-serialized size that matters the most and that management call ought to be able to get a value pretty close to correct (although if it's transitive, it might be necessary to do a bunch of finagling to temporarily set references to null before computing the size).

Is there a trick to getting a table's data updated using Ajax (eg when
a
DropDownChoice value changes - without refreshing the whole page)?
I started with a table that got update by its ListView with no Ajax.
That
worked well.
Now, I try to use a WebMarkupContainer to wrap the ListView so I can
update
the table by Ajax.
final ListView lines = new ListView(lv,myList){
@Override
protected void populateItem(ListItem item) {
item.add(...); // derive and add 1st name
item.add(...); // derive and add 2nd name
}};
WebMarkupContainer listContainer = new WebMarkupContainer(wmc);
listContainer.add(lines);
form.add(listContainer.setOutputMarkupId(true));
the my most recent try at mark-up looks like:
table border =1 align=center
thead
tr
thfirst name/th
thlast name/th
/tr
/thead
tbody
tr wicket:id=wmc
td wicket:id=fNfirstName/td
td wicket:id=lNlastName/td
/tr
/tbody
/table
