You could try count++. I think that would work, but would probably have to
play with it to be sure.
The @Table component also has an "index" parameter that would allow it to
update a property of your choice with the current row index value. Maybe
that's what you wanted.

Hello
I have a problem with migration to TAP 4.1.2
previously I'm use some increment operation in template
(tst="ognl:count=count+1")
<tr jwcid="tableRows1" class="
org.apache.tapestry.bean.EvenOdd.next" row="ognl:row" cid="ognl:row.id"
tst="ognl:count=count+1">
<td jwcid="tableValues1" align="center"/>
</tr>
and calculate total display rows
after migration all works, but occur exception:
