RE: DB lookup time-out within DataTable Iterator
Hey!
@Ernesto,
Thx for the idea, but I am afraid that won't be the way to go. The issue
is coming with the initial page having the table, I am not having a set
of search parameters at that moment. The thing is that I was looking for
some way to interact with the table 'after' giving the dataprovider to
the table.
@Mike,
Aha, you're so close to the problem we're having here! Exactly that is
happening: the H2 database we are using has some problems with the
combination of the SELECT/WHERE/ORDER. It is not using an index in that
case, a known problem with this database we just found out :-(
So, a solution might be switching to another DB, or solving it in the
user interface, just as you are mentioning. Can you shine a light on way
to go for having another page component render based on the provider? I
Thx!

Onderwerp: Re: DB lookup time-out within DataTable Iterator
Hi Frank ,
Are you sure that your dao is setting max results on the underlying
query? The provider.iterator(...) should only be returning the current
page values and typically the page size would be small like 25 to 100.
Also it depends on your backend database since I know that some (older
version of PostgreSQL) have issues with doing a SELECT ... ORDER BY X
LIMIT Y without looking at all of the values in the unlimited select.
If the total number of rows is reasonable (say several 1000) then just
return the full list into Java and then use a Comparator to sort the
loaded data according to the sort property.
In terms of handling this issue in your interface you can just have
another component render based on the value from the provider. If you
can cache the results of the provider like the loadable detachable model
does then there will only be 1 hit on the db and then you can show zero
rows in the table and an error message label.
Regards,
Mike
Breaking my head on the following, hopefully someone might be able to
give me a hint?
In a page which serves a view on a log database with quite a lot of
rows, I am using a DataTable to show the rows. The data for the table
is being served by a SortableDataProvider which looks a bit like this:
...
public SortableSystemlogDataProvider(Map searchParams) {
// creating new instance, set default sorting, Search parameters,
counting dataset
this.dao = new H2InterfaceDaoImpl();
setSort(sl_id, false);
this.searchParams = searchParams;
this.systemlogListSize = dao.countAllSystemlogRows(searchParams);
}
public Iterator iterator(int first, int count) {
SortParam sp = getSort();
if (sp.getProperty() == null) {
setSort(sl_id, false);
sp = getSort();
}
// return iterator on search list by params
paginatedList = dao.selectSystemlogs(this.searchParams,
sp.getProperty(), sp.isAscending(), first, count);
return paginatedList.iterator();
}
...
The issue I am running into at this moment is this: in case of large
datasets, the db call from within the iterator gives a timeout, and
returns null. In this case I would like to give the user a warning
modalwindow and the possibility to change the search options. Of
course I am able to catch the timeout, and return an empty set, but I
cannot see how to move on from that, as I am already within the
DataTable.
Anyone has an idea on this?
Thanks in advance, regards,
Frank Prins

Re: How to run some JS only once after Ajax rendering is done ?
Hi have you tried invoking AjaxRequestTarget's method appendJavascript? Inside if statement try to write AjaxRequestTarget.get().appendJavascript(jQuery.initEdit();); I had a similar problem some weeks ago and it worked. It won't be run only once even if added multiple time (for example from different instances of the same behavior attached to different components). thx still :) ++ joseph - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

I think you could do it as follows. The js function 'bindYourEvent()'

hi Bernard
The issue with this approach is that I would then have to think of
adding the JS every time some re rendered components need some init call.
However, as BUQUET Fabrice said, it works with
IHeaderResponse.renderOnDomReadyJavascript.
thanks anyway

Re: checkGroup - 2 out of 5?
and still need that validator... 2010/9/7 Xavier López xavil...@gmail.com To switch the last check with the first checked in case there are two of them checked already, you could also use an AjaxFormComponentUpdatingBehavior to do it server-side, though that would only be disadvantages. I remember some nasty issues with the onchange event on checkboxes with IE, and the server-side ajax would be just doing dom attribute manipulations. You'll be much better off doing it with JS, as Igor stated. Cheers, Xavi 2010/9/7 nino martinez wael nino.martinez.w...@gmail.com yup validator's more correct 2010/9/7 Xavier López xavil...@gmail.com I'd do it with a component validator. That would avoid the Form's onSubmit being called and getting the model updated with incorrect user data. Or also with a FormValidator. If I remember correctly, you can call getConvertedInput to get the Checkgroup's list of selected values.

How can I capture the data on one panel 1 when i click submit button on panel 2
Hi,
I have a page and multiple panels added to it.
e.g I have panel1 and panel2 added to a page.
On Panel I have components RadioChoice, dropdownchoice,text area that
accepts input from the user.
Panel 2 has two textfields (accepts the login info) and submit button.
When i click submit button on panel2, how can I capture the data from
panel1.
Here is my panel1
public class ImageQualityPanel extends Panel {
public ImageQualityPanel(String id, WicketAnalysisForm aform) {
super(id);
ImageQuality imageQuality = new ImageQuality(); //model
add(new ImageQualityForm(imageQualityForm, new
CompoundPropertyModel(imageQuality), aform));

public ImageQualityForm(String id, IModel model, WicketAnalysisForm
aform) {
super(id, model);

add(new RadioChoice(qualityGroup, options);
add(new RadioChoice(criteriaGroup, options);

RE: How can I capture the data on one panel 1 when i click submit button on panel 2
What you want is to implement the EventBus pattern (formally Observer
Pattern).
Basically, with an Eventbus, your panels subscribe to a given event and
when some other panel fires that event the subscriber gets the
message:
Panel1:
//Subscribe to event Type1.
eventBus.addHandler(EventType1.class,
new EventType1Handler() {
@Override
public void oneEvent(final EventType1 event) {
//do whatever with the event
}
});
Panel2:
onClick(.){
//After some action, fire that something has change to
all
//those subscribers that might be interested.
eventBus.fireEvent(new EventType1(whatever));
}
I'm quite new using Wicket, but I haven't seen anything like this
implemented. But I think it's quite trivial. It would be quite nice if
Wicket itself provides you with an out-of-the-box EventBus, the same way
GWT does.
Have a look to the GWT implementation, you can practically copy-paste
it. There it's called HandlerManager.
I don't know what's the standard way to solve the problem you have.
Surelly everybody has run into it sooner or later. I'm very interested
in hearing what a seasoned Wicket developer has to say.

Wicket Ajax integration
How can I use Wicket.Ajax.Request to post a json string to a

On the Javascript side I basically did something like this:
function setupSend(xhr) {
xhr.setRequestHeader(Wicket-Ajax, true);
if (typeof(Wicket.Focus.lastFocusId) != undefined
Wicket.Focus.lastFocusId != Wicket.Focus.lastFocusId != null)
xhr.setRequestHeader(Wicket-FocusedElementId,
Wicket.Focus.lastFocusId);
xhr.setRequestHeader(Accept, text/xml);
};
function success(data) {
var xml = data;
if (typeof xml == string) {
xml = new ActiveXObject(Microsoft.XMLDOM);
xml.async = false;
xml.loadXML(data);
}
(new Wicket.Ajax.Call(${feedbackURL})).loadedCallback(xml);
};
function call(data, revertFunc) {
$.ajax({
url : ${feedbackURL}, type: 'POST', contentType:
'application/json;charset=UTF-8'
,dataType: (($.browser.msie) ? text : xml), data :
$.toJSON(data)
,beforeSend : setupSend ,success : success, error : revertFunc
});
};
to do something similar to what Wicket.Ajax.Request.post does, except I
change the contentType to 'application/json'
