Help with ognl

[Andrea Chiumenti <ki...@gmail.com>]

hello,
I have an ognl expression inside a @For component and I'm using tap 4.1.1

"ognl:id + '-cg-' + (index + 1)"

the index is an int property.
I expect the result to be:

comp-cg-1
comp-cg-2
comp-cg-3
etc. but instead I've back

comp-cg-01
comp-cg-11
comp-cg-21

How to sum index + 1 and append the result to the string ?

Of course I could add a method to the java component getIndexPlus1(), but
it's ugly.

Thx,
kiuma

Sounds like a potential ognl bug as well. The (index + 1) expression
should be interpreted as a separate addition expression from
everything else.

If you would be so kind as to file an issue here:

http://jira.opensymphony.com/browse/OGNL

I can take a look at fixing it during the next release.

Thx Richard,
In your opinion whats better/smarter:
1) "ognl:id + '-cg-' + (index * 1 + 1)"
2)"ognl:id + '-cg-' + add(index,1)"

?

It's ugly, but one answer is  "ognl:id + '-cg-' + (index * 1 + 1)",
using the multiplication to force interpretation as a number.
