I would like to display a table containing a list of all items related to a particular option. If the selected option does not have any associated items, a message 'No Items Found' should be displayed. I implemented it by checking if the list of items that will be retrieved from a database will return nothing. In this case, I was able to display in my jsp a message informing the user that no items are found and the table containing the list of items otherwise. My problem is that since upon loading, my list does not contain any values since the user has not selected any option, the message is already displayed.

<!-- Display table of items based on selected option -->
<logic:notEmpty name="myForm" property="myList">
<tiles:insert page="myListTiles.jsp" flush="true">

<!-- Display message if no items are associated with the option >
<logic:empty name="myForm" property="myList">
<A>No Items</A>

Can anyone help me how I can resolve this? Thanks in advance.
