This is a problem I've been chasing for quite some time, but have only just returned to be able to examine in any detail, subsequent
to finding out that, yes, Project Woodstock is completely dead in the water, and rapidly sinking: I need to have a page which has an
AddRemoveList on it. The "selected" side of the list needs to be prepopulated. So you can visualise what I am talking about, this
current page is for editing a group of users. The "available" side of the list contains all the users not in the group, the
"selected" side is the users in the group. I have tried a great number of different approaches, and I cannot prepopulate the
"selected" side.
I just downloaded and installed NB 6.5, and built a dummy project containing nothing but a page with an AddRemoveList on it. I then
modified the prerender() method:
public void prerender() {
Option[] choices = new Option[3];
for (int i = 0; i < choices.length; i++) {
choices[i] = new Option("choice"+i, "choice"+i);
}
getAddRemoveList1DefaultOptions().setOptions(choices);
String presel="option5";
getAddRemoveList1DefaultOptions().setSelectedValue(presel);
getAddRemoveList1().setValue(presel);
}
and also tried this:
public void prerender() {
Option[] choices = new Option[3];
for (int i = 0; i < choices.length; i++) {
choices[i] = new Option("choice"+i, "choice"+i);
}
getAddRemoveList1DefaultOptions().setOptions(choices);
String[] presel = new String[]{"choice4","choice5"};
getAddRemoveList1DefaultOptions().setSelectedValue(presel);
getAddRemoveList1().setValue(presel);
}
The page paints with the control having "choice1".."choice3" in the "available" side, but the "selected" side remains empty. I will
be delving into the Woodstock code to track down what is going on (if I can work out which is the correct version of the code to
examine), but need some assurance that the approach I have taken above is correct.
