messagesPresent giving NullPointerException

in what cases the logic:messagesPresent will give NullPointerException.I am consistently getting the exception.
Tried to unzar/decompile the tag class file and looked into the code too...but NullPointer seems to be taken care of....
Any pointers will be helpful

Mind posting a snippet of the JSP here where you're using it?

The whole portion below is in one Jsp and 2.) follows 1.) immediately

1.)

<logic:messagesPresent message="true">
<html:messages id="msgItem" message="true">
<TR <app:rotateStyle id="msgStyle" classes="messageRow altMessageRow"/>>
<TD><bean:write name="msgItem" filter="false"/></TD>
</TR>
</html:messages>
<TR>
<TD width="500" nowrap><img src="../content/transpixel.gif" width="1" height="7" border="0" alt=""></TD>
</TR>
</logic:messagesPresent>

2.)
<logic:messagesPresent>
<html:messages id="errItem">
<TR <app:rotateStyle id="errStyle" classes="errorMessageRow altErrorMessageRow"/>>
<TD><bean:write name="errItem" filter="false"/></TD>
</TR>
</html:messages>
<TR>
<TD width="500" nowrap><img src="../content/transpixel.gif" width="1" height="7" border="0" alt=""></TD>
</TR>

</logic:messagesPresent>

The tag of 1.) gives problems.If I comment 1.) and leave 2.) as it is,everything goes fine.

Hmmm...do you know which tag is actually causing the exception? Is it the logic:messagesPresent tag or the html:messages tag? What if you were to try something this:

If that works, we know it's the html:messages tag, if not, it's the logic:messagesPresent tag.

Well,it is messagesPresent Tag only.Since I commented evrything inside the 1st messagesPresent tag and got exception.
