ui:repeat offset and size performs incorrect validation
-------------------------------------------------------
Key: MYFACES-3034
URL: https://issues.apache.org/jira/browse/MYFACES-3034
Project: MyFaces Core
Issue Type: Bug
Components: General
Affects Versions: 2.0.3
Environment: OpenJDK 1.6.0_20; Tomcat 6.0.20; Ubuntu 10.04 on kernel
version 2.6.32-28-generic
Reporter: Rey Dalisay
The following ui:repeat tag with those values of size and offset throw a
FacesException with the message: "iteration offset cannot be greater than
collection size."
<ui:repeat var="listing" value="#{myListings.listings}" size="19" offset="20">
It appears that the method _validateAttributes() in the UIRepeat class performs
the validation incorrectly. It seems to assume that the value of size is the
size of the collection, rather than the desired iteration size. Here is the
relevant code from _validateAttributes():
if ((size > -1) && (begin > size)) {
throw new FacesException ("iteration offset cannot be greater " +
"than collection size");
}
The exception is thrown in the above case because begin > size, where begin =
offset = 20.
