Summary
Tag name:
<tr:forEach>
The forEach tag is a replacement for the JSTL <c:forEach> tag. Though as of JSF 1.2/JSP 2.1/JSTL 1.2, <c:forEach> can be used with any JSF components or tags, it does not support "varStatus". This tag adds support for varStatus (other than "current" which is not supported). (Note : this tag is not supported in Facelets, because c:forEach is fully functional in Facelets.) Unlike the old Trinidad tr:forEach built with JSF 1.1, however, this tag can be used with any JSP 2.1-based tag, JSF or non-JSF. This tag also has a limitation not found in <c:forEach>: <tr:forEach> does not currently support arbitrary java.util.Collections; it can only iterate over java.util.Lists or arrays.
Example:
<tr:selectOneListbox value="#{someValue}"> <tr:forEach var="item" items="#{model.listOfItems}"> <tr:selectItem value="#{item.value}" text="#{item.text}"/> </tr:forEach> </tr:selectOneListbox>
<tr:forEach varStatus="vs" begin="1" end="5"> <tr:outputText id="ot2" value="#{vs.index} #{vs.count} #{vs.begin} #{vs.current}"/> </tr:forEach>
