Hallo,
in a WORepetition I have placed a WOImageButton for deleting something,
identified by the index of the repetition.
Therefore I have bound an action "delete" to the action tag of
WOImageButton, created there an new tag "todelete" and bound to the
index of
WORepetition.
if i understand you correctly, you created a binding on the
WOImageButton like "todelete = index". that is not necessary.
if you have an image button that calls a method in a repetition, you
just need one binding and that is the action binding.
if you are using the count / index combination of bindings on the
repetition, index will be set on the correct number if you click on
your button. you just call the method like
public void deleteItem()
{
//for example
myArray.removeObjectAtIndex(index); //where index is bound to the
index of the repetition
}
if you are using the list / item combination of bindings on the
repetition, the item is set as you click on the button. so, you have no
problem there.

But how can I get in action "delete" the value of "todelete" for
programming
the deletion?
Thanks for your advices
