Please help with logic notPresent

[Alex Colic <al...@pop-ware.com>]

Hi,

I have an object in the session that if it is not there I want to display
and error msg to the user. My error code is as follows:

<logic:notPresent name="VendorResourceList" scope="session">
  <font color="red">
    <bean:message key="error.fatal" />
  </font>
</logic:notPresent>

I would think that the above code would show the message if the
"VendorResourceList" object is not found in the session but the error msg
is always displayed even though the below code snippet works.

<TABLE>
  <TR>
    <TD>
      <bean:message key="prompt.vendorNumber"/>
    </TD>
    <TD>
    <logic:present name="VendorResourceList" scope="session">
	I am here
   </logic:present >
   </TD>

Amy help in understanding this is appreciated.

Alex

Be sure you've included the logic tld. The "I am here" would display
regardless, since the browsers ignore tags they don't understand.
