Hi Alex,
It works but I have an Exception on submit when the app is setting the
checkBoxes value. I get : Exception Message ! Index (i) out of bounds [0, i-1]
"i" is the number of checkBoxes checked.
When I check all, there are no Exception. So What am I doing wrong?
Thanks

Sujet : Re: How to get each CheckBox value inside a WORepetition Bind to the
same variable
Your WORepetition should have
list = listIng
item = currentIngenieur
your WOCheckbox :
checked = ingChecked
your Java :
public boolean ingChecked()
public void setIngChecked(...)

Hi Alex,
Thanks for your help, but when I use your example I have
javaNullPointerException because the checkBox "checked" is bound to this method
:
public boolean isIngChecked() {
return listIng.containsObject(currentIngenieur.diplSpecAbr());
===>JavaNullPointerException
}
and java don't like the returned value. When I return a boolean variable, it
works but there another problem on setter method. WO don't the setter method so
I have this exception :
<sig.utt.fr.Session 0xe956bd> takeValueForKey(): attempt to assign value to
unknown key: 'isIngChecked'.
This class does not have an instance variable of the name isIngChecked or
_isIngChecked, nor a method of the name setIsIngChecked or _setIsIngChecked
public void setIngChecked(boolean isIngChecked) {
this.isIngChecked = isIngChecked;
boolean isAlreadySelected = isIngChecked();
if (!isAlreadySelected && isIngChecked)
listIng.addObject(currentIngenieur.diplSpecAbr());
else if (isAlreadySelected && !isIngChecked)
listIng.removeObject(currentIngenieur.diplSpecAbr());
}
My CheckBox :
ingenieurCheck : WOCheckBox {
class = "texte";
name = "ingenieur";
checked = isIngChecked;
//value = currentIngenieur.diplSpecAbr;
//onclick = "IngChecked(this.form)";
}

Hi,
you need an array to store the selected objects, here's un example to a
selection of movies.
Bind the checkbox's selection to "movieSelected" :
You need to use the "checked" binding of WOCheckBox, not "selection"...
public boolean movieSelected() {
return selectedMovies.containsObject(currentMovie);
}
public boolean setMovieSelected(boolean checked) {
boolean isAlreadySelected = movieSelected();
if (!isAlreadySelected && checked)
selectedMovies.addobject(currentMovie);
else if (isAlreadySelected && !checked)
selectedMovies.removeObject(currentMovie);
}
Cheers
Alex

Hi,
[snip]
masterCheck : WOCheckBox {
class = "texte";
name = "master";
*To Chuck ===> Why I can't give the same name of my checkboxes?*
selection = selectedMaster; ----->Variable bind to check box value
value = master.diplSpecAbr; --->CheckBox value
// onclick = "MstChecked(this.form)";----> JS function wo call a java method to
get checkbox value
The only binding you need to get the checkbox value is the "value" binding.
This is two-way, just like a WOString. When the page is displayed, it will try
to evaluate diplSpecAbr or getDiplSpecAbr. When the form is submitted, it will
call setDiplSpecAbr. (Or it will try to read and set the variable, if that's
what it is vs. accessor methods.)
You don't need the "selection" or "onclick" to get the values back.
master.diplSpecAbr, for each item, will just be set to the value automatically
when the form is submitted.
===>When I don't put 'selection' in attribute of my checkBox in WOD I have this
error : if either selection or value is bound, then both must be bound. So
it's important to have 'selection' attribute for a checkBox in WO.
===> If I don't have 'selection' which is bound to the value of my checkBox,
How I get my selectedValue in the nextPage of my apps?
For checkboxes, it's often useful to have accessor methods in the page's java
that explicitly translates between the checkbox's boolean and the meaning in
the object. You would have access to the "master" item from the repetition
there, so implementation is straightforward.
===>I have my accessor methods in the page's java. When I select the checkBox,
it set the value the selection variable. and when I want to get this value, I
call get of the selection variable. But in this case, we are in another
context. Do you have an example for me?
Thanks
