Re: jahia_calendar default value

Hi Philippe,

Thanks for the prompt response. Unfortunately your example does not help
me. For me it stops at:

jParams.getSession().getAttribute("jahia_session_engineMap");

There is no attribute "jahia_session_engineMap" in the Session. My
session contains the following attributes:

attr: 10_5_nieuwsContainer9_search_handler
attr: 6_8_siteSettings_filter_handler
attr: org.jahia.services.multilang.currentlocale
attr: 13_5_nieuwsContainer12_search_handler
attr: 12_8_nieuwsContainer11_filter_handler
attr: 12_5_nieuwsContainer11_search_handler
attr: 11_5_nieuwsContainer10_filter_handler
attr: fiUser
attr: org.jahia.usermanager.jahiauser
attr: 6_8_siteSettings_sort_handler
attr: 8_5_topMenu_sort_handler
attr: 6_8_siteSettings_search_handler
attr: 8_8_topMenu_search_handler
attr: 10_8_nieuwsContainer9_search_handler
attr: 8_5_topMenu_filter_handler
attr: 11_8_nieuwsContainer10_sort_handler
attr: 11_5_nieuwsContainer10_search_handler
attr: 6_5_siteSettings_sort_handler
attr: 13_8_nieuwsContainer12_filter_handler
attr: 8_8_topMenu_filter_handler
attr: 11_5_nieuwsContainer10_sort_handler
attr: 12_5_nieuwsContainer11_filter_handler
attr: 10_8_nieuwsContainer9_filter_handler
attr: org.jahia.engines.lastenginename
attr: 12_8_nieuwsContainer11_sort_handler
attr: org.apache.struts.action.LOCALE
attr: op
attr: 6_9_siteSettings_filter_handler
attr: 11_8_nieuwsContainer10_filter_handler
attr: 6_5_siteSettings_filter_handler
attr: 12_8_nieuwsContainer11_search_handler
attr: 8_9_topMenu_filter_handler
attr: 8_9_topMenu_sort_handler
attr: 13_5_nieuwsContainer12_filter_handler
attr: 8_9_topMenu_search_handler
attr: 12_5_nieuwsContainer11_sort_handler
attr: 6_9_siteSettings_sort_handler
attr: org.jahia.services.sites.jahiasite
attr: 8_5_topMenu_search_handler
attr: org.jahia.params.lastrequestedpageid
attr: 10_5_nieuwsContainer9_sort_handler
attr: LastPageID
attr: 10_5_nieuwsContainer9_filter_handler
attr: 13_8_nieuwsContainer12_sort_handler
attr: 6_9_siteSettings_search_handler
attr: 11_8_nieuwsContainer10_search_handler
attr: 13_5_nieuwsContainer12_sort_handler
attr: 10_8_nieuwsContainer9_sort_handler
attr: 8_8_topMenu_sort_handler
attr: 6_5_siteSettings_search_handler
attr: 13_8_nieuwsContainer12_search_handler

Should this example work for my version of Jahia? Or do I have to put
the session engine in the Session explicitly?

thanks,
Hilbert
