problem with ChoiceRenderer
Hi folks,
after hours of elaborating, searching docu and trying I'm totaly lost. My
ChoiceRenderer is not
working.
Here is my code (not relevant code has been removed):
markup:
select id=1 wicket:id=zoznam/select
page implementation:
public class PageEshop extends PageBase{
public PageEshop(){
ChoiceRendererVyrobok renderer = new ChoiceRendererVyrobok();
ListVyrobok vyrobky = Arrays.asList(new Vyrobok(start, -Vyberte typ-), new Vyrobok(polstar,
Polštář), new Vyrobok(deka, Deka));
Vyrobok defaultChoice = vyrobky.get(0);
DropDownChoiceVyrobok vyberVyrobku = new DropDownChoiceVyrobok(zoznam, new
PropertyModelVyrobok(defaultChoice, kluc), vyrobky, renderer);
FormObject form = new FormObject(inputForm);
form.add(vyberVyrobku);
this.add(form);
}
}
pojo:
public class Vyrobok implements Serializable{
private String kluc;
private String hodnota;
public Vyrobok(String kluc, String hodnota){
this.kluc = kluc;
this.hodnota = hodnota;
}
//getters and setters for attributes
}
IChoiceRenderer implementation:
public class ChoiceRendererVyrobok implements IChoiceRendererVyrobok{
@Override
public Object getDisplayValue(Vyrobok vyrobok){
return vyrobok.getHodnota();
}
@Override
public String getIdValue(Vyrobok vyrobok, int index){
return vyrobok.getKluc();
}
}
When page is loaded, this error happens (not complete stack, not relevant
removed):
Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to
cz.polstareadeky.utils.Vyrobok
at
cz.polstareadeky.ChoiceRendererVyrobok.getIdValue(ChoiceRendererVyrobok.java:1)
at
org.apache.wicket.markup.html.form.AbstractSingleSelectChoice.getModelValue(AbstractSingleSelectChoice.java:194)
at
org.apache.wicket.markup.html.form.FormComponent.getValue(FormComponent.java:837)
Something is wrong in ChoiceRendererVyrobok but I can't find what..
Any help is apreciated,
thanks, Michal

Re: problem with ChoiceRenderer
just now I have elaborated that this works:
DropDownChoiceVyrobok vyberVyrobku = new DropDownChoiceVyrobok(vyberVyrobku,
new PropertyModelVyrobok(defaultChoice, null), vyrobky, renderer);
(note `null' in PropertyModel)
but strange is that I don't know why :-(

you're instructing the DropDownChoice to get its model object from your
defaultChoice:
new PropertyModelVyrobok(defaultChoice, kluc)
This is probably not what you've intended as Kluc is a String. Something like
the following would make more sense:
this.selectedChoice = vyrobky.get(0);
new PropertyModelVyrobok(this, selectedChoice)

Hi,
the type of the model and of the renderer must be the same chosen for the
DropDownChoice (Vyrobok in your case). In the first version of your code this
was not
true for your model because it pointed to a String field (named kluc).
Your second version works fine because you don't provide a property expression
to PropertyModel (is null) and doing so the property model considers as model
object the first parameter of its constructor (defaultChoice in your case),
which is an instance of class Vyrobok.
But at this point it does not make much sense to use a PropertyModel, you could
substitute it with a Model class, like this:
Model.of(defaultChoice)
just now I have elaborated that this works:
DropDownChoiceVyrobok vyberVyrobku = new DropDownChoiceVyrobok(vyberVyrobku,
new PropertyModelVyrobok(defaultChoice, null), vyrobky, renderer);
(note `null' in PropertyModel)

yes, now I see, mea culpa
thanks for pointing me this

dropdown and values added with jquery
Hi,
in my Page (not relevant code removed for simplicity) is dropdown:
public class MyPage extends WebBase{
//perie
private ModelPerie modelPerie;
//two values in dropdown:
private ListPerie perie = Arrays.asList(new Perie(start, -Vyberte druh peří-), new
Perie(vsypek, nové 806));
private DropDownChoicePerie vyberPeria;
private ChoiceRendererPerie rendererPerie;
public PageEshop(){
this.rendererPerie = new ChoiceRendererPerie();
this.modelPerie = new ModelPerie(this.perie.get(0));
this.vyberPeria = new DropDownChoicePerie(vyberPeria,
this.modelPerie, this.perie, this.rendererPerie);
MyForm form = new MyForm(inputForm);
form.add(vyberPeria);
this.add(form);
}
private class MyForm extends FormObject{
public MyForm(String id){
super(id);
}
@Override
protected void onSubmit(){
//with value added with jquery this produce error
System.out.println(PageEshop.this.modelPerie.getObject().getHodnota());
}
}
}
and in relevant markup I add new choice in this dropdown with jquery:
form wicket:id=inputForm
div id=perie
labelTyp peří:/label
select id=2 wicket:id=vyberPeria/select
/div
script
jQuery(document).ready(
function()
{
//--this add another value into dropdown, now there are three
values:
$('#2').append($('option/option').val('testkluc').html('testovaci text'));
})
/script
/form
Of course, when I select this added value ('testkluc') in dropdown and submit
it, from onSubmit() I try to do something with this, I get error:
...
java.lang.reflect.InvocationTargetException
...PageEshop$MyForm.onSubmit(...
Yes, I know that this third value isn't in model so error is predictable.
Question is: how to deal with situation when I need
add new value in HTML and this value isn't in my model in java?
Thanks,
MJ

DownloadLink
Hi,
what to add into onClick() in DownloadLink if I need return to client generated
.pdf
stream as a .pdf file?
My code:
IModel pdfStreamModel = new AbstractReadOnlyModel()
{
public Object getObject()
{
return getPdfStreamBytes();
}
};
DownloadLink downloadLink = new DownloadLink(downloadLink, pdfStreamModel,
getPdfDocumentName())
{
public void onClick()
{
System.out.println(clicking works);
}
};
Model works, DownloadLink is added into my markup. But I can't find any example
how to deal
code into onClick() in DownloadLink in a way it will return my generated .pdf
stream in model.
Thank folks,
MJ

Re: DownloadLink
Dan, thank you for links and points.
The true is that I have data in database so I would like streaming them. Is the
right
way put them in temp file first and then send it into browser with DownloadLink?
After some googling I noticed that ResourceLink should be like DownloadLink but
for me
better - it's for streamed data. But can't find any example for wicket 1.5 :-(

Also check out the code for DownloadLink itself, and you'll see
1. Your IModel must return a File, but yours returns bytes.
2. The download is initiated in DownloadLink#onClick, which you have
blocked with your subclass.
Hope that helps,

Re: DownloadLink
Ok, so this is my code (works, irrelevant striped):
public class PageIndex extends PageBase{
...
...
...
final Integer fileDbIdTmp = (Integer) oneResult.get(fileId);
final byte[] bytes = new String(content of the created file for
download).getBytes();
ResourceLinkVoid downloadLink = new ResourceLinkVoid(downloadLink, new
AbstractResource()
{
private Integer fileDbId = fileDbIdTmp;
@Override
protected ResourceResponse newResourceResponse(Attributes attributes)
{
ResourceResponse r = new ResourceResponse();
r.setFileName(mypdf.pdf);
r.setContentType(application/pdf);
r.setContentDisposition(ContentDisposition.ATTACHMENT);
r.setContentLength(bytes.length);
r.setWriteCallback(new WriteCallback()
{
@Override
public void writeData(Attributes attributes)
{
//here, the data for .pdf should be loaded on-demand from DB with
some appropriate model...
MyDAOObject myDBData = new MyDAOObject(fileDbIdTmp);//just pseudo-code
attributes.getResponse().write(myDBData.loadData());
}
});
return r;
}
});
panelEvent.add(downloadLink);
this.add(panelEvent);
...
...
...
}
Now I would like construct LoadableDetachableModel (using this model for
loading strings for same panels) or something similar
so I can construct data from DB based on some id (I have DB id of the element -
in this case .pdf file stored in DB).
After consult doc:
http://wicket.apache.org/apidocs/1.5/org/apache/wicket/markup/html/link/ResourceLink.html
I can't see where to put model, or where to hook model into ResourceLink.
In my code in writeData() there is line for loading data but I think this is
ugly solution...
Any help appreciated.

find html tag
Hi,
is there a way I can find specific html tag in markup?
I have this html structure:
ul class=mymenu
li
a href=./mypage.html?cid=menumenu/a
ul
li
a href=./mypage.html?cid=menu/submenusubmenu/a
ul
li
a href=./mypage.html?cid=menu/submenu/subsubmenu1subsubmenu1/a
/li
li
a href=./mypage.html?cid=menu/submenu/subsubmenu2subsubmenu2/a
/li
li
a href=./mypage.html?cid=menu/submenu/subsubmenu3subsubmenu3/a
/li
/ul
/ul
/ul
I'm processing clicks on anchors with my page:
public PageTest(PageParameters parameters){
//cid = category id
String category = parameters.get(cid).toString();
...
}
Now I need some way I can add atribute into parent li tag of a tag on which
I do click.
Somethink like (pseudocode):
public PageTest(PageParameters parameters){
//cid = category id
String category = parameters.get(cid).toString();
//find corresponding a tag
Tag anchorTag = go_from_top_ul_tag_and_find_a_tag_by_category(category)
//have corresponding anchor tag, get parrent tag of the anchor tag
Tag anchorParentTag = anchorTag.getParent();
//and now I can do my mysterious things with menu...
}
But I don't know where to start my search and I totaly don't know whot to look
for in docu.
Please, help :-)

Re: find html tag
Problem is that uls and lis (let's call whole structure menu) is static html
code.

Hi!
What you want to accomplish (e.g. changing some html attributes) can be done by
adding an attributemodifier to each li component.
In pseudocode:
RepeatingView uls = ...
for_every_li:
WebMarkupContainer li = ...
uls.add(li);
now, you can do something like this:
li.add(new AttributeAppender(...) {
isEnabled() {
return true if you want to append a html attribute;
}
});
Or alternatively:
WebMarkupContainer li = new WMC() {
onComponentTag(ComponentTag tag) {
super(tag);
tag.put(my-html-attribute, value);

Re: find html tag
I need to find the parent li tag of the anchor user clicks - I now from
PageParameters which anchor

(id=something). This attribute
will be then processed by JavaScript on the page.

Re: find html tag
Structure is static and I can't (management decision) generate it dynamically.
Everythink I have is
static html and category user has been clicked.

Theoretically you can access the html markup and fiddle with it, but that's
generally not how wicket is meant to be used. (Trust me, we've been doing quite
some
advanced stuff with wicket over the years).
If all you want to do is change the html code, you can also do that with some
javascript code.
E.g. override renderHead() in your page and contribute some javascript code for
onLoad.
But before doing such things: is there a particular reason why you are using
static html instead of a component tree?
Are you able and willing to switch to a component tree?

Re: find html tag
Look at my original post. User clicks on a
href=./mypage.html?cid=menu/submenu/subsubmenu2subsubmenu2/a, then
I have in String category (java code) value menu/submenu/subsubmenu2. I
need just to make 2 more steps:
1. in html code find anchor tag with href menu/submenu/subsubmenu2;
2. find li tag which is parent of the anchor from point 1;
When I have point 2 done, then I know how to put somethink into li tag...

Since you wrote (in your folluw-up e-mail) that you cannot generate the html,
there are some ways, but they mostly work outside of the normal wicket way.
1) In the component which actually renders your static html override
onComponentTagBody and fiddle with the markup stream (e.g. look at
replaceComponentTagBody)
2) store the static html somewhere by itself, and create a custom model.
The model can then load the html and perform string replacement.
You can then add a label component which uses the model and has
setEscapeModelStrings(false) set.

Re: find html tag
again with my question: is it possible to get markup in onRender() of the
component?
have found this article:
https://cwiki.apache.org/WICKET/component-rendering.html
but in onRender() section is just code snippet I'm not understand. is there more
detailed example how to get markup of the component in onRender()?

I'm processing clicks on anchors with my page:
public PageTest(PageParameters parameters){
//cid = category id
String category = parameters.get(cid).**toString();
...
}
Now I need some way I can add atribute into parent li tag of a
tag on which I do click.
Somethink like (pseudocode):
public PageTest(PageParameters parameters){
//cid = category id
String category = parameters.get(cid).**toString();
//find corresponding a tag
Tag anchorTag = go_from_top_ul_tag_and_find_a_**
tag_by_category(category)
//have corresponding anchor tag, get parrent tag of the anchor tag
Tag anchorParentTag = anchorTag.getParent();
//and now I can do my mysterious things with menu...
}
But I don't know where to start my search and I totaly don't know
whot to look for in docu.
Please, help :-)

}

Since you wrote (in your folluw-up e-mail) that you cannot generate the
html, there are some ways, but they mostly work outside of the normal
wicket way.
1) In the component which actually renders your static html override
onComponentTagBody and fiddle with the markup stream (e.g. look at
replaceComponentTagBody)
2) store the static html somewhere by itself, and create a custom model.
The model can then load the html and perform string replacement.
You can then add a label component which uses the model and has
setEscapeModelStrings(false) set.

In pseudocode:

Re: find html tag
in fact, my panel is menu which is modified by javascript.
i need to keep track of the previous selected entry (to get know

so i need to modify html markup, modify it on client side by

I have in String category (java code) value

I need just to make 2 more steps:
1. in html code find anchor tag with href
menu
Re: find html tag
no way how to modify raw html stream in actual rendering?

It doesn't give you the html from the previous page render.
You need to send Ajax requests to update the server side state to be in
sync with the client side state (modified by your JS).

Maybe you don't need to bother with internals like MarkupStream for
something that may be solved much easier.

Re: find html tag
Paul, thanks. Looks like I'm just two steps from final. My current code in
MyPanel (stupid,
at the moment just for test):
@Override
public void onRender()
{
MarkupStream markupStream = this.getAssociatedMarkupStream(false);
while(markupStream.hasMore())
{
String myString = markupStream.next().toString(); //after last html
element I get null
//pointer exception
but markupStream.hasMore()
//indicate that there
is more elements
myString = myString.replaceAll(menuso, someelse);
System.out.println(myString);
}
}
two more questions:
1. markupStream.hasMore() is going over MyPanel markup, when go over all markup
it's going beyond border and after last html tag I get null pointer exception
on markupStream.next()
2. how to write modified markup back to markupStream? Have found this:
Response response = this.getResponse(); //in MyPanel - MyPanel is Component
(extends Panel)
response.write(CharSequence); //is this right way to write modified stream
back to response?
will test same with onComponentTag(ComponentTag component), based on this:
http://stackoverflow.com/questions/4609871/wicket-getting-body-of-markup-element
now know hot to get markupStream (2 days ago my big problem).
sorry for my stupid questions, i'm still n00b ...

You can also do it inside the onComponentTag() or onComponentTagBody():
http://wicket.apache.org/apidocs/1.5/org/apache/wicket/Component.html#onComponentTag(org.apache.wicket.markup.ComponentTag

http://wicket.apache.org/apidocs/1.5/org/apache/wicket/Component.html#onComponentTagBody(org.apache.wicket.markup.MarkupStream,
org.apache.wicket.markup.ComponentTag)
This is how I switched from a DIV to a SPAN when nesting forms since
Wicket uses DIV that sometimes breaks my CSS inheritance:
/**
* Wicket by default will substitute inner nested forms with DIV elements,
we want SPAN
* elements to preserve the page layout.
*
* @see org.apache.wicket.Component#onComponentTag(ComponentTag)
*/
@Override
protected void onComponentTag(final ComponentTag tag) {
super.onComponentTag(tag);
if(!isRootForm()) {
tag.setName(span);
}
}
