Request paramter value is truncated to first part when it contains spaces

Answer 1

As said by BalusC in his answer the problem is with your value assignment.

Modify your code as :

<select name="locdropdown" onchange="javascript:change()" > 
<%
for(LocationDO locationDO : locationList)
{%>
<option value="<%=locationDO.getLocationName().trim()%>" >
        <%=locationDO.getLocationName().trim()%>
</option> 
<%} 

%>
</select>

Hope this helps.
