Hello,
I am testing MyFaces 2.1.1 implemantation, in order to upgrade our
aplication from version 1.2.7.
I have found a problem with parameters offset and size of ui:repeat tag.
offset sets the first index of the list to iterate over.
size is the number of element to iterate.
If I have a list of Strings like this:
private String[] textos = new String[] {"B1", "B2", "B3", "B4", "B5",
"B6", "B7"};
public String[] getTextos() {
return textos;
}
And I declare repeat tag:
<ui:repeat value="#{bean.textos}" var="texto" offset="0" size="1">
<h:outputText value="#{texto}"/><br/>
</ui:repeat>
It shows elements B1 and B2 (iterate over indexes 0 and 1). If I change
offset to 1, it will show elements B2 and B3.
But if I set offset="2" in order to ietare over indexes 2 and 3
(elements B3 and B4), I get an exception:
javax.faces.FacesException: iteration offset cannot be greater than
collection size
at
org.apache.myfaces.view.facelets.component.UIRepeat._validateAttributes(
UIRepeat.java:552)
at
org.apache.myfaces.view.facelets.component.UIRepeat.process(UIRepeat.jav
a:581)
...
If I want to avoid this error, size must be allways greater tha offset,
but it should be possible to iterate over last two elements of a 102
elements list starting from index 100, for example (offset=100,size=1).
And should not be "1" the lower value for size? Now, if you set 0 to
size, ui:repeat iterates once...
Thanks in advance,
Ricard
