jsf - Facelets repeat Tag Index

Question

Does anyone know a way to get the index of the element in a ui:repeat facelets tag?

<ui:repeat id="topTenGrd" var="dream" value="#{dreamModifyBean.topDreams}">
    <h:outputText class="dream-title uppercase" value="#{dream.number}. #{dream.title}" />
</ui:repeat>

Answer 1

Specify a value for the "varStatus" attribute:

<ui:repeat id="..." var="..." value="..." varStatus="myVarStatus">

You can then access the loop index via EL:

#{myVarStatus.index}

Additionally, the following properties are available to the varStatus:

• begin of type Integer
• end of type Integer
• index of type int
• step of type Integer
• even of type boolean
• odd of type boolean
• first of type boolean
• last of type boolean
