Re: dynamic DataTable
Someone in another forum advised me this:
***
Maybe in latest Wicket something changed but in 1.4.16 you can't change
Columns in DataTable. So it's immutable in some sense.
But you may replace whole DataTable component instead when your sql
statement changes:
form.add(new Button(sqlSubmit) {
void onSubmit() {
String sql = ...;
form.replace(createDataTable(myDataTable, sql));
}
})
form.add(createDataTable(myDataTable, null));
Where createDataTable() creates DataTable using provided id and sql string.
Also there is a convenient method Component.replaceWith(). Maybe it'll fit
better to your coding style.
***
I think this is what I need, but I dont know how to do. Can someone please
help me to create below method?
*createDataTable(wicketId, SQL)*
Thanks,

I see your problem Davut, but I really don't think Wicket can solve it in
the
way you want it to. As Martin said, you need an entity to populate the
models used by the various Wicket components.
Could you somehow parse the SQL statement to extract the table name, and
find its meta data?

Re: Issues with HeaderResponseContainerFilteringHeaderResponse
Hi,
It is not documented by wicket:head contributes before
#renderHead(). This may change in the future so don't rely on it.
Better take a look at
http://wicketstuff.org/wicket/resourceaggregation application. There
you can see how resources are scored. This way you can setup
org.apache.wicket.resource.filtering.HeaderResponseContainerFilteringHeaderResponse.IHeaderResponseFilter
which renders your specific contribution after all other.
To render CSS text use
org.apache.wicket.markup.html.IHeaderResponse.renderCSS(CharSequence
css, String id). Use the id in the filter to recognize it.

Under normal circumstances I would, but I don't have my css in a file. It

contributer classes and resource references assume there's a file somewhere
with this info. But in my case there is not.
And, even id I did stuff this data into a file it still wouldn't fix my
problem, because the customer defined css needs to override everything else
with the same css selector. If another component added a header contributor
afterwards that would not be the case.

setHeaderResponseDecorator(new IHeaderResponseDecorator() {

Re: DateTimeField and setOutputMarkupId()
I don't see any problem.
Put a break point in AjaxRequestTarget.addComponent() and see what is
registered. If you see component with id hours then investigate the
stacktrace.
As last resort you can create a quickstart with plain Wicket
components and if it still fails with this error send it to us in a
ticket.

Hi Martin
Thanks for looking at this. It's a bit complicated because we've built a
form framework around Wicket, but here goes:
In the page:
HtFormPanel.DateFormField startField = new
HtFormPanel.DateFormField(startField,
new StringResourceModel(start, this, null), new PropertyModelDate(this,
start), false);
Where the constructor for HtFormPanel.DateFormField is:
public DateFormField(String uniqueId, IModelString label, IModel m,
boolean bShowTime)
{
// The DateTimeField is contained within the DateFormField
super(uniqueId, FieldType.DATETEXTFIELD.toString(),
(bShowTime ? new DateTimeField(FIELD_ID) :
new DateField(FIELD_ID)), label, m);
}
Next, in the page:
startField.setFieldOutputMarkupId(true);
// The radio button that does the ajax update:
final HtFormPanel.RadioFormFieldReportAction actionField = new
HtFormPanel.RadioFormFieldReportAction(
actionField,new ResourceModel(actionField),actionTypes,new
LocalizedChoiceRendererReportAction(this),
new PropertyModelReportAction(this,action));
Finally, the update code that causes the problem:
actionField.getFormComponent().add(
new HtAjaxFormChoiceComponentUpdatingBehavior() {
private static final long serialVersionUID = 8574977146235850631L;
protected void onUpdate(AjaxRequestTarget target) {
if (getAction() != null
getAction().equals(ReportAction.VIEW)) {
startField.setRequired(false);
} else {
startField.setRequired(true);
}
// We update the startField and the DateTimeField inside it.
target.addComponent(startField);
target.addComponent(startField.getComponent());

I'm porting this sample scala/wicket application from Wicket 1.4 to 1.5.
I've almost completely got it figured out except for this bit of code from a

EntityManager/Transaction stuff):
override def onEndRequest =
{
super.onEndRequest()
if (em != null)
{
if (em.getTransaction().isActive()) em.getTransaction().commit()
em.close()
}
// TODO: in 1.5 page maps no longer in use - not sure why they'd want to
do this to begin with...
// TODO: ahhh, maybe to prevent hitting 'back button'?
//if (_endConversation) getRequest().getPage().getPageMap().remove()
}
The line I have commented out at the end is what I can't find an equivalent
for in Wicket 1.5.
Whether or not this is the proper way to do database stuff is really not
important to me - please don't let that distract from the question. For
those that are curious, the _endConversation flag is set in the body of a
form's onSubmit() method, after data is written to the database.
What I'm really interested in is
a) Why would someone want to remove the page map from the session in Wicket
1.4? like above Is my comment correct that it prevents hitting the back
button and re-submitting a form?
no idea
b) What is the Wicket 1.5 way of handling a situation like this? I looked
at some other related posts on these forums, but haven't found a good
description yet.
c) In general, how does page caching work in Wicket 1.5? There isn't much
on the migrating wiki page...
The migration page has a note at the top mentioning other wiki pages for 1.5.
There is a page for cache http headers and page storages. You need the
second one.
Thanks,

AjaxEventBehavior(onchange) and AjaxFormComponentUpdatingBehavior(onchange) on same DropDownChoice
Hi guys,
I'm very new to Wicket, and I came across this:
What I want to do:
- I have a DropDownChoice component and I'd like to update it's model
when it changes through AJAX. Also, I want to refresh (repaint,
reload) this dropdown's parent when a value is changed, also though
AJAX.
My approach:
- Adding an AjaxEventBehavior(onchange) AND an
AjaxFormComponentUpdatingBehavior(onchange). Here's the code:
dropDownChoice.add(new AjaxEventBehavior(onchange) {
protected void onEvent(AjaxRequestTarget target) {
LOG.debug(DroDownChoice's parent +
IntegrityLevelDropDownPanel.this.getParent().getParent().getParent());
target.addComponent(IntegrityLevelDropDownPanel.this.getParent().getParent().getParent());
}
});
dropDownChoice.add(new AjaxFormComponentUpdatingBehavior(onchange) {
@Override
protected void onUpdate(AjaxRequestTarget target) {
LOG.debug(New updated value: +
this.getComponent().getDefaultModelObjectAsString());
target.addComponent(this.getComponent());
}
});
The Problem:
- Unfortunately both onchange events don't work together. Depending
on the order of my code, the AjaxFormComponentUpdatingBehavior or the
AjaxEventBehavior are executed, but not both.
I've changed one of them to happen onblur and then they're both
executed, but this is not a solution to my issue.
Does anybody have any tips for this? I've been searching for a while
but couldn't find anything that solves this.
Thank you in advance,

Re: AjaxEventBehavior(onchange) and AjaxFormComponentUpdatingBehavior(onchange) on same DropDownChoice
Hi Clint,
Thank you very much for your (quick) response.
I had the (maybe incorrect) idea that AjaxEventBehavior's
target.addComponent(aComponent) would only make aComponent refresh
itself through AJAX (and not store new changed values on it's model).
I also thought that the AjaxFormComponentUpdatingBehavior's
target.addComponent(aComponent) would make the opposite: save
aComponent's model without a form submission (thorugh AJAX) but
without refreshing anything.
I'll apply your changes and check if, onchange, new values are
stored in the dropdown's model and it's parent is refreshed to show
the changes.

Re: PageMap in 1.5
Let me simplify my original question. If in the past I could do this: getRequest().getPage().getPageMap().remove() a) What was the practical purpose of removing page maps from sessions (i.e., this API existed for a purpose - what was it)? b) What do I do in 1.5 to accomplish the same thing now that PageMaps are gone? I suspect this has something to do with back button support and page history. This wiki page (https://cwiki.apache.org/WICKET/caching-in-wicket-15.html) discusses caching, true. I guess what I'm looking for is a discussion of PageManager (the replacement for PageMaps).

Re: dynamic DataTable
Hi,
Here is the outline of a possible implementation :
Execute SQL String
Create a ListIColumnSQLResultRow
for each SQL result column:
add a column to the list that displays one column of a SQLResultRow
Create a very simple ISortableDataProvider that returns the SQL result
from above
(make it more complex to implement sorting)
Create a DataTable using the column list and the data provider

Maybe in latest Wicket something changed but in 1.4.16 you can't change
Columns in DataTable. So it's immutable in some sense.
But you may replace whole DataTable component instead when your sql
statement changes:
form.add(new Button(sqlSubmit) {
void onSubmit() {
String sql = ...;
form.replace(createDataTable(myDataTable, sql));
}
})
form.add(createDataTable(myDataTable, null));
Where createDataTable() creates DataTable using provided id and sql string.
Also there is a convenient method Component.replaceWith(). Maybe it'll fit
better to your coding style.

I think this is what I need, but I dont know how to do. Can someone please
help me to create below method?

Could you somehow parse the SQL statement to extract the table name, and
find its meta data?

Re: PageMap in 1.5

I'm porting this sample scala/wicket application from Wicket 1.4 to 1.5.
I've almost completely got it figured out except for this bit of code from a
class that extends RequestCycle (it does some basic
EntityManager/Transaction stuff):
override def onEndRequest =
{
super.onEndRequest()
if (em != null)
{
if (em.getTransaction().isActive()) em.getTransaction().commit()
em.close()
}
// TODO: in 1.5 page maps no longer in use - not sure why they'd want to
do this to begin with...
// TODO: ahhh, maybe to prevent hitting 'back button'?
//if (_endConversation) getRequest().getPage().getPageMap().remove()
}
The line I have commented out at the end is what I can't find an equivalent
for in Wicket 1.5.
Whether or not this is the proper way to do database stuff is really not
important to me - please don't let that distract from the question. For
those that are curious, the _endConversation flag is set in the body of a
form's onSubmit() method, after data is written to the database.
What I'm really interested in is
a) Why would someone want to remove the page map from the session in Wicket
1.4? like above Is my comment correct that it prevents hitting the back
button and re-submitting a form?
i can only guess and say that all pages in the pagemap are part of the
conversation and once the conversation is over/discarded the pagemap
is removed so pages in that pagemap/conversation are no longer
accessible. if the user tries to click back to a page and click any
link on it they will get the page expired exception.
b) What is the Wicket 1.5 way of handling a situation like this? I looked
at some other related posts on these forums, but haven't found a good
description yet.
dont think we have a replacement for this, actually. what we would
need is ipagemanager#removePage(int id). that will only handle
removing a single page though. if you have more pages that are part of
a conversation you will have to track them all so the last page of the
conversation knows all other pages that paricipated. this should be
easy since somehow you must already be propagating the conversation
somehow. then when conversation is over the code can access the list,
from pages metadata?, and remove all pages. feel free to add an rfe
for the remove() method.
c) In general, how does page caching work in Wicket 1.5? There isn't much
on the migrating wiki page...
martin has already answered that in another email...

Re: DateTimeField and setOutputMarkupId()
Martin, thanks for your help. Igor's hint helped me. After some
investigation I realized that I have a visitor in my button's submit handler
that visits all form components and adds them to the ajax target. That meant
it was visiting the inner fields of the DateTimeField, also, which was not
necessary. I fixed it by ignoring form fields in the visitor that don't have
outputMarkupId set.

Put a break point in AjaxRequestTarget.addComponent() and see what is

As last resort you can create a quickstart with plain Wicket

new StringResourceModel(start, this, null), new

Where the constructor for HtFormPanel.DateFormField is:

{
// The DateTimeField is contained within the DateFormField
super(uniqueId, FieldType.DATETEXTFIELD.toString(),

HtFormPanel.RadioFormFieldReportAction(
actionField,new ResourceModel(actionField),actionTypes,new

Getting Post DATA
I am very new user of wicket, so please be gentle with me if this is obvious question or RTFM. I tried searching for docs but no luck. Using Wicket 1.5. I have bunch of pages mounted using mountPage(url, page class). This works fine and pages do get parameters so long as the request is GET. If you do post on the same url, pages don't see the same parameters. I tried searching google for the solution and came across one solution at http://apache-wicket.1842946.n4.nabble.com/Manually-handle-post-data-td1853028.html However seems like I can not resolve QueryStringUrlCodingStrategy class in wicket 1.5. Tried looking for replacement calls, but no luck so far. These are services and there is no UI for this. A script will typically post the data to the service.

Wicket documentation suggestion
Not sure if this is the right forum to post, but I presume many decision makers are lurking here. When googling for class documentation, google typically shows multiple results. I have caught myself looking at wrong version of docs many times. This is especially useful if there methods that are deprecated or we have new way of doing things in better way. From this perspective, I like what Microsoft does. They tell you that you are looking at documentation of version X and have a link to jump to other versions if required. Example at http://msdn.microsoft.com/en-us/library/system.data.dataset.aspx I know for API docs, we can see 1.4 or other versions in url bar, but I think this might be really useful to have a link to jump to other versions.

Better take a look at
http://wicketstuff.org/wicket/resourceaggregation application. There
you can see how resources are scored. This way you can setup
org.apache.wicket.resource.filtering.HeaderResponseContainerFilteringHeaderResponse.IHeaderResponseFilter
which renders your specific contribution after all other.
To render CSS text use
org.apache.wicket.markup.html.IHeaderResponse.renderCSS(CharSequence

Handling futures
Hello, I can't find the correct way to handle java.util.concurrent.Future instances returned from asynchronous methods in Wicket. This interface does not extend Serializable so its instances can't be stored in components or pages. So what do you do with them? Do you store them in a map in the application and keep a handle (e.g. an int) in the Wicket component? I saw code on a github repository that implemented an ajax timer behavior that keeps a reference to a Future in a transient field to update a status. However, I can't understand how that would work. Wouldn't the transient field be nulled out if the behavior is serialized with the page and then deserialized? Essentially, my question is: what is the standard way to handle Futures in Wicket that run longer than the page rendering? (like processing an order or sending emails) I hope I'm not missing something obvious, but that might be the case...
