DB lookup time-out within DataTable Iterator
Hi guys!
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: DB lookup time-out within DataTable Iterator
Hi Frank,
Just an idea... If you do the filtering via AJAX you could use the
same AJAX request to:
1- display a modal window in case you get the timeout error: just
place the ModalWindow on your page do
modalWindow.addOrReplace(new
MyErrorMessagePanel(modalWindow.getContentId())); and use
modalWindow.show(target) to show it.
2-Place your filters on a panel (orWebMarkupConatiner) that can be
update via AJAX, reset the filter bean you are using to populate the
filters and update this panel via AJAX.

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.

Re: checkGroup - 2 out of 5?
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.

issue using executeAjaxEvent for a test
Hi All,
I have an issue trying to test an ajax event.
I have two different wicket classes which need to talk each other.
Both classes have a TextField plus a ListMultipleChoice. When the user
types a word into the class A textField the items of the class A list
get filtered and, based on
the new class A list choices, the class B list gets filtered as well.
To achieve that I have the following on the class A textField
//Class A
new OnChangeAjaxBehavior()
{
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
protected void onUpdate(AjaxRequestTarget target)
{
[12]
listMultipleChoice.setDefaultModelObject(getValue(txtField.getDefaultModelObjectAsString()));
ListString selectedClassAItems = getSelected();
classB.filterByClassAItems(selectedClassAItems);
target.addComponent(classB.getListMultipleChoice());
target.addComponent(listMultipleChoice);
}
};
which actually it's working fine.
To test it I have the following
textFieldString classATextField = (TextFieldString)
classAWicketTester.getComponentFromLastRenderedPage(panel:ajaxMultiChoiceform:filterBox);
classATextField.setDefaultModelObject(filtered);
classAWicketTester.executeAjaxEvent(classATextField.getPageRelativePath(),
onchange);
ListMultipleChoiceString classAItems =
(ListMultipleChoiceString)
classAWicketTester.getComponentFromLastRenderedPage(panel:ajaxMultiChoiceform:filteredList);
assertEquals([filteredItem],
classAItems.getChoices().toString());
ListMultipleChoiceString classBItems =
(ListMultipleChoiceString)
classBWicketTester.getComponentFromLastRenderedPage(panel:ajaxMultiChoiceform:filteredList);
assertEquals([filteredClassBItem],
classBItems.getChoices().toString());
###
Now the issue is that for some reason using the executeAjaxEvent, to
fire the onchange event, the model into
txtField.getDefaultModelObjectAsString() (line 12) is always null
hence I cannot retrieve the text value set and filter both lists.
I've checked during the debugging the ids of the component and they
are exactly the same, so I'm sure the textField called here in line 12
is the same one used to set
classATextField.setDefaultModelObject(filtered);
but for some reason even if it's the same the model is null.
Any clue? Is executeAjaxEvent enough the fire the onUpdate?
Regards
Antonio

Inmethod datagrid adding aggregate rows
Hi, I'm looking for some hints for doing the following: I have an Inmethod datagrid, which has the columns 'amount', 'product', 'detail', 'price'. I would like to have at the bottom of the table (just above the paging toolbar) an extra row which shows me the sum (total) of all prices in the list. How I calculate these values (sum of the showed items, or sum of ALL items), should not matter, I want to add these cell values by just giving a model. But, the sum() column should be located under the 'prices' column. I did try this via a custom Toolbar, where I add a div with it's own table element. This seems to work, but I do not get the styling right. The columns of this table should have the same width als the columns of the 'body' table. Digging into the code, I saw that some javascript is used for doing the sizing. Can anyone give me some hints what is the best approach to get the column's size correct? (or maybe I'm doing this completely wrong?)

How to run some JS only once after Ajax rendering is done ?
hi
I've some components which require some client side javascript which
require one init call (for all) to be initialized. In fact, this init
call uses selectors to get at the components to work one.
My issues is with Ajax. It happens that, during it, some new components
required this init call are added.
As such, how could I trigger it only once per Ajax request ?
The pattern I'm targeting is for each component to initialize this way
to have a behavior in which something would be added only in Ajax
request cycle. For non ajax request cycle, I use jquery to do the init,
through:
$(document).ready(function(){
$.initEdit();
});
When trying to reach this goal, I tried to run the init call through an
header contributor, but the call is then done before my content is put
on the page, making it useless:
public abstract class AbstractEditBehavior extends AbstractBehavior
{
public AbstractEditBehavior(final AbstractTextComponent? component)
{
component.add(JQueryDependency.CORE);
component.add(new HeaderContributor(new IHeaderContributor()
{
public void renderHead(final IHeaderResponse response)
{
if ((AjaxRequestTarget.get() != null))
{
response.renderJavascript(jQuery.initEdit();, ID
+ response.hashCode());
}
}
}));
}
(...)
thanks in advance
best

Re: Inmethod datagrid adding aggregate rows

Hi Joseph,
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.

Re: DiskPageStore with Terracotta
i believe the cleanup happens on session timeout. so if terractotta is preserving sessions forever then wicket will not cleanup the filestore. this is without me actually checking the code. you can force a size of each file, but that file is per session, so if you have unlimited sessions i dont think thats going to help. -igor On Tue, Sep 7, 2010 at 8:22 AM, Jeremy Levy jel...@gmail.com wrote: When using Terracotta WebSessions 3.3.0 with Wicket 1.4.9 on JBoss 4.2 / Tomcat6 the DiskPageStore grows infinitely.

Error in FormTester with 1.4 but not with 1.5
Hi list
with the following test
public void testFormAndLinkAreSubmitted()
{
WicketTester tester = new WicketTester();
tester.startPage(FormPage.class);
FormPage page = (FormPage)tester.getLastRenderedPage();
Assert.assertFalse(page.isSubmitLinkSubmitted());
Assert.assertFalse(page.isFormSubmitted());
FormTester formTester = tester.newFormTester(form);
formTester.setValue(field, 2);//added
formTester.submitLink(link, true);
page = (FormPage)tester.getLastRenderedPage();
Assert.assertTrue(page.isFormSubmitted());
Assert.assertTrue(page.isSubmitLinkSubmitted());
tester.assertModelValue(form:field, 2);//added
}
extracted from FormPageTest present in the wicket code base i get a test
file on the line tester.assertModelValue(form:field, 2); (the model has
value 1 (the default) instead of 2), this acts like the FormTester miss to
process something. The same test executed with wikcet 1.5-M1 (the trunk)
terminate successfully, while with official release 1.4.10 fails.
I can't imagine why with 1.4 fail.
Is it a plan to back port on the 1.4 branch the changes that fixed this test
on the trunk?
Best regards, thanks in advance

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

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: DB lookup time-out within DataTable Iterator
It could be returning only 25 rows, but the criteria itself is what
makes the query slow. In that case, I'd recommend looking at your
indexes. Sometimes indexing doesn't help very much, though.

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.

How can I attach the Transaction to the thread to get this working?

This has nothing in particular to do with Wicket, and would be hard to
answer without knowing the details of what you are doing for transaction
management.

Re: Error in FormTester with 1.4 but not with 1.5
wicket tester in trunk and in 1.4.10 have diverged a lot due to
changes in trunk. there may not even be anything to backport, this bug
may have been fixed as part of making wickettester work with changes
in trunk.

extracted from FormPageTest present in the wicket code base i get a test
file on the line tester.assertModelValue(form:field, 2); (the model has
value 1 (the default) instead of 2), this acts like the FormTester miss to
process something. The same test executed with wikcet 1.5-M1 (the trunk)
terminate successfully, while with official release 1.4.10 fails.
I can't imagine why with 1.4 fail.
Is it a plan to back port on the 1.4 branch the changes that fixed this test
on the trunk?

Hi all, The wicketstuff repo is down again. Is there any chance the tagged artifacts from the wicketstuff repo can be synced to a more reliable Maven repo (central even)?

Hi Steve, Wicketstuff-core artifacts have been released through the oss.sonatype.org repository and into central since version 1.4.7.

Re: How to run some JS only once after Ajax rendering is done ?
I think you could do it as follows. The js function 'bindYourEvent()' is
called after the the components that are added to the AjaxRequestTarget
are 're-painted'.
form.add(new AjaxButton(set) {
@Override
protected void onSubmit(final AjaxRequestTarget target,
final Form? form) {
target.appendJavascript(bindYourEvent(););
}
});

hi
I've some components which require some client side javascript which
require one init call (for all) to be initialized. In fact, this init
call uses selectors to get at the components to work one.
My issues is with Ajax. It happens that, during it, some new
components required this init call are added.
As such, how could I trigger it only once per Ajax request ?
The pattern I'm targeting is for each component to initialize this way
to have a behavior in which something would be added only in Ajax
request cycle. For non ajax request cycle, I use jquery to do the
init, through:
$(document).ready(function(){
$.initEdit();
});
When trying to reach this goal, I tried to run the init call through
an header contributor, but the call is then done before my content is
put on the page, making it useless:
public abstract class AbstractEditBehavior extends AbstractBehavior
{
public AbstractEditBehavior(final AbstractTextComponent? component)
{
component.add(JQueryDependency.CORE);
component.add(new HeaderContributor(new IHeaderContributor()
{
public void renderHead(final IHeaderResponse response)
{
if ((AjaxRequestTarget.get() != null))
{
response.renderJavascript(jQuery.initEdit();, ID
+ response.hashCode());
}
}
}));
}
(...)
