dynamic selection on dropdown

Hello, I have DCT which has some select box (dropdown) and required dynamically make selection base on folder. I can catch everything, but how can I select properly some element from dropdown.

[HTML]
Site Placement

[/HTML]

When I tried this code (below) it almost works, but selection is not right. When I alert correct one it show properly.

function setSelection(path, sobj) {
    var options = sobj.getOptions();
    var newOptions = new Array();
    for (var a in options) {
        if (path == options.value) {
            newOptions = new Option(options.text,options.value,false,true);
//            alert("Selected : " + options.text);
        } else {
            newOptions = new Option(options.text,options.value,false,false);
        }
    }
    sobj.setOptions(newOptions);
}

It would be a great help if someone could suggest some idea to solve this problem.

That's the second time I see "alert miracle" in conjunction with drop-down modifications.

You may want to take a look [thread=19430]here[/thread]. I do not know of any resolution but perhaps you would be able to coordinate your efforts with Ammu.

try this..

function setSelection(path, sobj) {
var options = sobj.getOptions();
var newOptions = new Array();
for (var a in options) {
if (path == options.value) {
newOptions = new Option(options .text,options .value,true,false);
// alert("Selected : " + options .text);
} else {
newOptions = new Option(options .text,options .value,false,false);
}
}
sobj.setOptions(newOptions);
}

If above does not work as well, try..

function setSelection(path, sobj) {
var options = sobj.getOptions();
var newOptions = new Array();
for (var a in options) {
if (path == options .value) {
newOptions = new Option(options .text,options .value,true,true);
// alert("Selected : " + options .text);
} else {
newOptions = new Option(options .text,options .value,false,false);
}
}
sobj.setOptions(newOptions);
}

moonkhanna - I tried all combination with true and false. It is doesn’t work. As ISCBorisB pointed earliest it is looks like a bug.

Even if it is a bug (it is far from certain) it does not mean that you can not adjust your code to bypass it.

For example, you share with Ammu the peculiarity of creating extra drop-down elements (comparing to DCT).
His case is extreme though (he has none originally). Yours seems to be milder. Is it possible to change/adjust
your drop down so that you modify only items' selection? Alternatively you may try to decrease *universal set* of
items by removing unneded ones, etc...

Try to play around it. Worst case scenario, you just use all available elements statically and validate onChange
with something like "Selection is not allowed in this Folder" Validation/Error Message. Sloppy, but easy to do.
