Actually, that would not work as written in a closure image. To make it work in closure image, you could write something like:

... aRenderer anchor callback: (makeCallBackWith: index ); ... And then write a method
makeCallBackWith: n ^[self callbackFor: n] In a non-closure image, it would work as written since fixCallbackTemps would have been sent automatically.

Hi all,

I'm experimenting different behavior between Seaside 2.8 and 3.0
regarding parameters passed in callback blocks. Attached there is code
to test in both platforms (just click in any of the first 8 links),
the problem is in the variable index in the #callback: of the
following code

renderBlabla

    | index |
    index := 1.
    8 timesRepeat: [
        aRenderer tableRow: [
            5 timesRepeat: [
                aRenderer tableData: [
                    aRenderer anchor
                        callback: [ self callbackFor: index ];
                        with: 'image link'.
                    index := index + 1.
                ]  ] ] ].

In Seaside 2.8 after clicking the link 3 for example, the
#callbackFor: method received 3 as parameter.
In Seaside 3.0 #callbackFor: receive 41.

I would like to preserve the parameter value configured in the
rendering phase, any suggestion how to do that in Seaside 3? (Using
PharoVM 4.0.2 12/4/2010 and Pharo1.1rc2 #11400)

Use an image with support for closures. Or if that's not possible, then send #fixTemps to the callback block.
