Number of items in browse.jsp

[back0rifice]

Hello!

Can someone please tell me how to determine the number of items in the two existing sections

* spaces
* content

in browse.jsp?!

I need this because I want to show/hide the section depending on if content exists or not. But unfortunately I have no idea how to figure out if there is any data to display in spaces and content section.

What I'd need is something like that:

<c:if test="${something.count > 0)">
   <%– Details - Content –%>
</c:if>

TIA!

nobody?  :?:

what i found out so far is this:

1.) <c:if…> seems to be ignored completely but i dont know why?!

2.)

<a:booleanEvaluator value="#{!empty BrowseBean.nodes}">
<%– Details - Spaces –%>
…
</a:booleanEvaluator>

works BUT i have to double-click each folder, that means i have to click it once - nothing happens - and afterwards a second time before the web client navigates to the "subdolder" and as in 1. i have no idea why this is happening?

i hope that anybody can help?  :?

Our pages are 99% based on JSF tags, which do not interoperate well with JSTL tags like you are using. So use of an outer <a:booleanEvaluator> tag or the rendered="true|false" attribute (available on virtually all JSF components) is the correct pattern.

I'm not sure why you are needed to click the items twice - are you using the BACK button? As this is a limitation of the MyFaces JSF library we are using - the BACK button is only supported after clicking twice on an item (to restore the server state).

Thanks,

Kevin

Ok, thanks for your answer.

Does that mean that the following lines of code should achieve the wanted result?

<%– Spaces List –%>
<a:richList id="spacesList" binding="#{BrowseBean.spacesRichList}" viewMode="#{BrowseBean.browseViewMode}" pageSize="#{BrowseBean.pageSizeSpaces}"
styleClass="recordSet" headerStyleClass="recordSetHeader" rowStyleClass="recordSetRow" altRowStyleClass="recordSetRowAlt" width="100%"
value="#{BrowseBean.nodes}" var="r" rendered="#{NavigationBean.searchContext != null}">‍‍‍‍

Of course I'm asking because it doesn't work…  :wink:


Edit: problem solved. The rendered attribute has to be used with the panel and doesn't work with the richList. Sorry, my fault…
