Hello,

I need themeDisplay from Liferay into backing bean. I am getting null. Anyone has a clue ?

Here is code:
javax.portlet.PortletRequest req = (javax.portlet.PortletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
RenderRequest renderRequest =(RenderRequest)req.getAttribute("javax.portlet.request");;
ThemeDisplay themeDisplay = (ThemeDisplay)req.getAttribute(WebKeys.THEME_DISPLAY);


Thanks

PS:

EXAMPLE PORTLET:

Here is a simple portlet that works fine:

LET ME KNOW IF I AM ON WRONG TRACK GO GET THEME FROM BACKING BEAN. DO I NEED THIS TAG THERE? ALSO EXCEPTION DISAPEARS IF I CHANGE <PORTLET-CLASS> IN PORTLET.XML

PORTLET.XML

<portlet>
<portlet-name>CompanyHeader</portlet-name>
<display-name>Company Header</display-name>
<portlet-class>com.icesoft.faces.webapp.http.portlet.MainPortlet</portlet-class>
<init-param>
<name>com.icesoft.faces.portlet.viewPageURL</name>
<value>/Test.iface</value>
</init-param>


Please help.

Hi Petar, You don't need that tag (as far as I know). I'm using Liferay 5.0.1 and my portlet is based on JSF, ICEFaces 1.7.....

Try the following on your backing bean:

FacesContext fc = FacesContext.getCurrentInstance();
ThemeDisplay themeDisplay = (ThemeDisplay)fc.getExternalContext().getRequestMap().get(WebKeys.THEME_DISPLAY);

BR, Lari

You are right, the tag is not needed.
There is a bug in liferay-icefaces that it does not forward this object to context.
Solution is here thanks to http://jira.icefaces.org/browse/ICE-2247
