Veclocity and Object properties in ArrayList
I am having problems getting properties from objects which are put into an
ArrayList. Here is the code which creates the ArrayList:
ArrayList lImages = new ArrayList();
for (int i=0; i<6; i++) {
ImageRef lImage = new ImageRef("Test"+i+".jpg", "This is a test "+i);
lImages.add(lImage);
}
lContext.put("images", lImages);
This is the class for the ImageRef:
private class ImageRef {
private String _FileName;
private String _Caption;
private ImageRef() {}
public ImageRef(String aFileName, String aCaption) {
_FileName = aFileName;
_Caption = aCaption;
}
public String getFileName() {
return _FileName;
}
public String getCaption() {
return _Caption;
}
}
This is the velocity template:
#foreach ($image in $images)
$image.caption
$image.Caption
$image.getCaption()
#end
Which produces the result:
$image.caption
$image.Caption
$image.getCaption()
$image.caption
$image.Caption
$image.getCaption()
$image.caption
$image.Caption
$image.getCaption()
$image.caption
$image.Caption
$image.getCaption()
$image.caption
$image.Caption
$image.getCaption()
$image.caption
$image.Caption
$image.getCaption()
I have gone through the manual, but with no luck. Any ideas?
Thanks

Don,
What do you get if you put a $image in that #for loop? I would suspect
that the private class is giving you problems with introspection. If
that is the case, could make the class implement a public interface?
