Strange problem with request.getParameter

Hi Experts,

I am facing a strange problem with getting values from URL.

So in my controller, I have two methods: getExcel and getChart.

getExcel renders a table in excel sheet and getChart renders a flash chart.

Both the methods have identical structure, except for the return statement.

Problem I am facing is with the variable liabilityCode in getExcel method.
String liabilityCode = request.getParameter("liabilityCode");

I am not able to fetch this value out of URL. where as the same liabilityCode is getting fetched perfectly fine in the method below it (getChart). The strange issue is, except for liabilityCode, I am able to fetch all other parameters. your insight on this would be highly helpful
