why do it in a complex loop like this? Why not set the selection as you
build each option:
Select mySelect = new Select("Test");
Option option1 = new Option("Option 1");
Option option2 = new Option("Option 2");
Option option3 = new Option("Option 3");
Option option4 = new Option("Option 4");
option1.setSelected(value.equals("Option 1")?true:false);
option2.setSelected(value.equals("Option 2")?true:false);
option3.setSelected(value.equals("Option 3")?true:false);
option4.setSelected(value.equals("Option 4")?true:false);
...
Granted, that gets messy if you have a lot of options in your Select, but if
that's the case why not do:
Select mySelect = new Select("Test");
for (int option_num = 1; option_num <= 4; option_num++) {
mySelect.addElement(new Option("Option " + option_num)
.addElement("HELLO " + option_num)
.setSelected(value.equals("Option " + option_num)?true:false)
);
}
Of course, your for loop will usually be some loop through a recordset from
a database in which case you'll use some other mechanism for naming the
options, but the principle is the same.
