How to use absolut container list ?

[Guillaume Sensenbrenner]

Hello,        I define an absolute container list on a page called "Advanced Search". Then, in other pages like "User", I get my absolute container list in order to add containers in it, to update them and so on.   Here is the code in order to get my absolut container list :   JahiaContainerList my_container_list = jData.containers().getAbsoluteContainerList( "my_container_list", advanced_search_page_id);   I get big troubles when I reboot jahia. When I try to update elements from my absolute container list in "User", I get an error message. If I go first on the "Advanced Search" page, it work. (see the error at the end of this post)  The following line causes the error: test_container.getField("astron_photo_gallery_creator").setValue(user.getUsername());   So how can I solve this problem ?   Thanks for all the suggestions that you could give me,  Regards   Here is the code of the "User Page": <%@ include file="astron_photo_gallery_page_id.jsp"%><%@ include file="astron_photo_gallery_entities_declaration.jsp"%><%@ include file="astron_photo_gallery_entities_tools.jsp"%><%@ include file="astron_photo_gallery_declaration.jsp"%>  <%/////////Initialisation of filtersContainerFilterBean astron_photo_gallery_container_filter_bean_first =new ContainerFilterBean("astron_photo_gallery_builder_name",jParams.getEntryLoadRequest());
