Yes Arturo, but doing this I need a Java method for each image...
I'm trying to do it in an unique Java method, but I need to pass it
the variable.

Hi Amedeo,
You bind to a Java method
public String imgPath() {
return "myPath" + filename;
}
No where did I say you bind to what you wrote. I said to set the
binding as David suggested.
Do the above then reread my email.

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.
