I guess I am asking for an ognl engine... to do these calculations within tml
files
be nice if there were an expression operator in T5 to do these...
guess I will have to make a java method...
any solutions or canonical approach are appreciated...

<t:outputRaw value=" (${cursor} + 1) "/>
this seems to produce "0 + 1" instead of the desired "1"
all i am trying to do is have the arithmetic performed before the output
thanks

Hi All,
I have this expression in a component definition...
<t:label for = "tableColumnsSelect"> ${cursor} + 1 </t:label>
For my case cursor is initially 0
After render... I view page source and I see the following...
0 + 1
when what I actually wanted to see is... the sum of the expression and the
value rendered...
1
Any tips on how i can do this ? Is there an arithmetic or expression operator
that I can prefix before my "${cursor} + 1" ?
Thanks
