Question

Can i write this:

<ui:repeat var="element" value="mybean.list">
<h:outputLink styleClass="#{myBean.otherList.contains(element)?'someclass':'someotherclass'}" />
</ui:repeat>

Answer 1

I think all you need is to wrap the myBean.otherList.contains(element) with another brackets () , like this (myBean.otherList.contains(element))

I do the same in several places

here an example

<h:panelGroup styleClass="#{(appRow.application.file)?'attachmentFileExist':'attachmentFileNotExist'}"></h:panelGroup>

here is how your should look like

<ui:repeat var="element" value="mybean.list">
    <h:outputLink styleClass="#{(myBean.otherList.contains(element))?'someclass':'someotherclass'}" />
</ui:repeat>

again , not sure about the extra brackets , but I use them in my pages

in order to check you code use development tools of you browser or firebug and just click on the cell to see it style class
