outputting expression logic

[Ken in Nashua]

Thanks Thiago... I didn't think it unreasonable to have fundamental ops to take 
code like this...

                <span jwcid="foreachitem@For" source="ognl:collection" 
value="ognl:currentObject" index="ognl:index">
                    <span jwcid="@If" condition="ognl:okToRenderItem">
                        
                        <span jwcid="@If" condition="ognl:( 
@java.lang.Math@min(tableColumns, itemsPerPage) )">
                            <span jwcid="@If" condition="ognl:((index - cursor) 
% @java.lang.Math@min(tableColumns, itemsPerPage) ) == 0">
                                <span jwcid="@Insert" value="</tr><tr>" 
raw="true"/>
                            </span>
                        </span>    

and have tap5 honor the same semantic (arithmetic and method calls) in some way 
or another...

I refuse to violate the page code and self contained components is pure 
tapestry anyway.

It seems I need chenelle...

Can you recommend a chenelle version for tap 5.3.0 ?

Thank You
