I want to update an ui:param value or use something similar in ui:repeat loops with a condition. The idea is something as follows (is just an aprox, not the final implementation but I guess is understandable):
<ui:param name="marginLeftNode" value="#{myBean.initialMarginValue}" />
<ui:repeat value="#{myBean.viewWrapper.linkMap.entrySet().toArray()}" var="map">
<ui:repeat var="link" value="#{map.value}" varStatus="status">
<li style="margin-left: #{marginLeftNode}%" class="ico-#{link.getStyleCss()}-ayuda">
<a href="#{link.getUrlLink()}">#{link.getTitle()}</a>
</li>
<!-- Code conditions that doesn't works in any way as I've readed in the links after code -->
<c:if test="#{marginLeftNode gt 4}">
<ui:param name="marginLeftNode" value="#{myBean.viewWrapper.nodeList.get(status.index).depth}" />
</c:if>
<ui:fragment rendered="#{marginLeftNode gt 4}">
<ui:param name="marginLeftNode" value="#{myBean.viewWrapper.nodeList.get(status.index).depth}" />
</ui:fragment>
<!-- End code conditions: these are the two solutions c:if and ui:fragmen I tried -->
</ui:repeat>
</ui:repeat>
I can't use c:if inside ui:repeat because doesn't works (Specify conditional rendering of element inside <ui:repeat>? The <c:if> does not seem to work) and I can't use ui:fragment with ui:param because it doesn't works too (Conditional variable definition in JSF)
So, any idea how to solve that?
