Select box empty after submitting the catalog item

[redth]

Hi,

I'm populating a select box (database name) based on the application selected in the catalog item using client and script include. After submitting the catalog item, the select box is empty and when I click on it, it shows the option I have selected. Used the similar script for many other catalog items and its working fine. See this issue only for this.

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var gr = new GlideAjax('getDb');
gr.addParam('sysparm_name','getDb1');
gr.addParam('sysparm_appName', g_form.getValue('app_name').toString());
gr.getXML(getdataname);

function getdataname(response){
g_form.clearOptions('u_dbName');
g_form.addOption('u_dbName','','---None---');

var msg = response.responseXML.documentElement.getAttribute("answer").split(',');

if(msg == ''){
alert('xxx');
g_form.clearValue('appName');
g_form.clearValue('appId');
g_form.clearValue('appLead');
}

else{
for(var i=0;i<msg.length;i++)
{
g_form.addOption('u_dbName',msg[i], msg[i]);
}
}
}
}

I have set the field 'clear variable name' to true in a UI policy by mistake. Set it to false and its working now. Thanks everyone for the inputs.
