callout refreshForm issue with select multiple

neski

I've notice a strange behaviour I've notice a strange behaviour in one of my CGI callouts using FormApi.

I’ve build a callout button that calls a CGI to choose one date from a calendar. The problem is that when one date is chosen and the opener.top.datacapture.refreshForm(); function is called we get a javascript error “Object doesn’t support this property or method”. I’ve also notice that this error is thrown only if no selection has been made from a single selection combo with size greater than 1.

In mozilla the javascript error is:

Error: uncaught exception: [Exception... "Index or size is negative or greater than the allowed amount"  code:
 "1" nsresult: "0x80530001 (NS_ERROR_DOM_INDEX_SIZE_ERR)" 
 location: "http://interwoven /iw/webdesk/templating/dc_item.js Line: 1897"]

This is the code:

 if ( formElement.type == "select-one" )
        {
     var selectedIndex = formElement.selectedIndex;
            var options = formElement.options;
            alert(selectedIndex);
var selectedOption = options[ selectedIndex ];
            var value = selectedOption.value;
            this.setOptionValue( value, true );
        }

I’ve found out that every single selection combo (with no selected value) in the datacapture has a selectedIndex = 0, but if it is a single selection combo with size greater than 1 it has a selectedIndex = -1, throwing a javascript error like shown.

I could workaround this problem simply by using a size=0 combo instead of a size=10, however I wanted to know if you think there is another solution or patch to solve this.

Thanks.
