Dunno if anyone else answered this.
You have a repetition with a list binding and an item binding. Call
the item binding filename.
For you image use the src binding as David says. WORepetition will
make sure that the filename is the one used for that particular loop of
the repetition. Here's an example.
Loop one
filename set to "britneyspears.jpg"
create WOimage
bind filename to imgSrc => "myPath" + filename =>
myPath/britneyspears.jpg
Loop two
filename set to "halleberry.jpg"
create WOimage
bind filename to imgSrc => "myPath" + filename =>
myPath/halleberry.jpg
Loop three ...
See, the repetition takes care of making sure that value of the bind
variable for the nested content (as they say in Struts-land) is
correct. But it also does it on form submit so that if you had a link
next to each image, when the link is clicked the filename binding will
be set to the value used to generate the link.

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())
But this won't work...
Any help?
Thanks

Hi
This is my problem...
I have a WORepetition...
the list item is an object containing a some stringa, strings are
image names.
I need to display the images using WOImage, but I need to prepend a
path to the image name.
I tried to make a binding line "myPath"+theFileName, but is not
accepted...
can I bind the WOImage src to a function thet return the String path?
How to pass theFileName to that function?
public String imgSrc() {
return "myPath" + listItem.theFileName();
}
Bind this to the WOImage src binding.
