parent.getScriptFrame() call fails in TS 6.0L

bikerider

This code worked in 5.5.2 SP 4, but does not work in 6.0L.
Am I missing something? The javascript error is:

Permission denied.

Here is the top of the javascript from the hidden frame:

<html>
<head>
<script language="javascript">
api = parent.getScriptFrame();
var v_prev_options;
var i = 0;
var j = 0;
var l = 0;
var v_selected;

// Put all current selections in to an array.
v_prev_options = api.IWDatacapture.getItem('c_preliminary_activity_information/grade_level_id').getOptions();

i = 0;
j = 0;
indexVal = 0;
selectedIndexTI_GRADE_LEVEL = new Array();
for (i = 0; i < v_prev_options.length; i++ ) {
if(v_prev_options.selected) {
selectedIndexTI_GRADE_LEVEL[j++] = v_prev_options.value;
}
}

// Get new options from the database
dbOptions = new Array();

v_selected = false;
for (l=0; l < selectedIndexTI_GRADE_LEVEL.length; l++) {
if (selectedIndexTI_GRADE_LEVEL == "101") {
v_selected = true;
l = selectedIndexTI_GRADE_LEVEL.length + 1;
}
}

dbOptions[0] = new Option("K-4", "101", v_selected, v_selected );


v_selected = false;
for (l=0; l < selectedIndexTI_GRADE_LEVEL.length; l++) {
if (selectedIndexTI_GRADE_LEVEL == "103") {
v_selected = true;
l = selectedIndexTI_GRADE_LEVEL.length + 1;
}
}
