Naa... I intentionally used a name I could be sure is not used anywhere else

Well, requestscope would be a problem, as soon as I get more than one
instances of the same tile for that request...

There must be something... I have replaced the c:when/otherwise construct
with a java if/else substitute like that:
<%
if (errmsg.toString().length() > 1) {
%>
<font color="#FF0000">
<tiles:getAsString name="FieldError"/>
</font>
<%
} else {
%>
<img src="/img/blank.gif" border=1 height="1" width="111">
<%
}
%>
Voila...works as expected ...
BTW: c:when test="${true}"> doesn't work either (just checked)

Let me rephrase the question ....
Is there any limitation on using JSTL in Tiles ???

Subject: Conditionally show values in Tile (c:when?)
Hi all,
I have a tile that shows my default input row in a form. In case that I put
a value in FieldError, I want it to show it the errorMessage in red color.
So far so good. The values get to the tile (formRow)... and there it's
getting somewhat tricky. After reading a number of explanations, I
understands that struts.apache.org recommends to use JSTL whenever
possible... thus I use the c:when/c:otherwise construct like follows
<tiles:useAttribute id="errmsg" name="FieldError" scope="page"/>
<td>
<%=errmsg.toString().length()%>
<%--correctly prints the expected value--%>
<c:choose>
<c:when test="${errmsg.toString().length() > 0}">
<font color="#FF0000">
<tiles:getAsString name="FieldError"/>
</font>
</c:when>
<c:otherwise>
<img src="/img/blank.gif" height="1" width="111">
<%--unexpectedly always shows this--%>
</c:otherwise>
</c:choose>
</td>
Substitutes using logic:greaterThat are showing the same strange behavior...
Any Idea why this happens ? Any Tutorials, I could look up ?
TIA,
albi
