Could not find any option to get the TEXT part of Select HTML control.
So, used the current index of select control as index of server connect query to get field directly.
Server Connect: serverconnectCountry
Select Control: selectSenderCountry
Text Input: inputCountry
inputCountry.setValue(serverconnectCountry.data.query1[selectSenderCountry.selectedIndex].countryName)
If any one finds a way to get the TEXT part when there is no server connect data, please share.
