Bean display failure

[Huhaibo <ha...@braveminds.com>]

	I wrote an application with a JSP to create Employee to database tables( using an action class ) and a JSP to list all employee in database. And the display of the latter JSP follows another action class( called ListEmployee ) , which retrieves data from database and construct a collection object in the request scope . The JSP looks like :
<table width="75%" border="1">
  	<tr>
    	<td>ID</td>
    	<td>Name</td>
    	<td>Age</td>
    	<td>Salary</td>
   		<td>Company</td>
  	</tr>
	<logic:iterate id="it" name="_EmployeeList">
  	<tr>
    	<td><bean:write name="it" property="id" /></td>
    	<td><bean:write name="it" property="name" /></td>
    	<td><bean:write name="it" property="age" /></td>
    	<td><bean:write name="it" property="salary" /></td>
    	<td><bean:write name="it" property="company.name" /></td>
  	</tr>
	</logic:iterate>
</table>
	
	When I display the list first time , it looks ok . But when I click the link again , it just return a blank page for me.Only restart will solve the problem( but that means I could only display once ).Could anyone tell me the reason and how to resolve it?
