[Seaside] passing additional parameters to an anchor callback

[Lukas Renggli]

Hi Johan

If you use a closure enabled Pharo image you might use method temps.
It also works in non-closure images but there you need to pass the
value through a value-holder.

In the particular code snippet below, I achieve this functionality by passing those values via an ajax call and have the callback block use those values. However, I'm not fond of that code since the values are required in the callback and not in the components themselves.
