Hi Amedeo,
Would you mind restating the question, because the way I'm reading it
it still seems that David's solution will work. As he states,
though, you might need a separate method for each occurrence of an
image in your .html, which would take the place of a static
parameter. (Of course, if it's not a static parameter but rather a
variable, it can be accessed directly from the method.)
That was the long way of saying variable and methods in conjunction
with WORepetitions and such cause lots of confusion when you're first
exposed to it, but it's because it's so simple and useful, you have
trouble believing it! ;-)
Regards,
Mark

thanks David, but this works fine If i have only an image in my
item object, but i have more images, so i need to pass to the
function the image name...
for example, following your example:
public String imgSrc(String aFileName) {
return "myPath" + aFileName;
}
and bind the WOImage to imgSrc(listItem.theFileName())
The bottom line is that there is no way to pass the parameter to
the method via a binding (without using WOOgnl from ProjectWONDER
that is).
You have a couple of options:
One would be to add a fileNameToPath cover method for each image.
However, I would probably fix this by creating a reusable component
that wraps WOImage (MYImage), has a filePath and fileName binding
that accepts the fileName appends the filePath and hands it off to
the WOImage src. This would eliminate any additional logic on your
main component, you could just bind it up.
