Here is the latest version of the class, it works, the page is displayed
but the doclist seems empty. 

Do you know how I can debug this  ? I've tried to add some
sys.stderr.write('problem') in the code but I have no output ...

class ListPage:
    '''This page shows the list of results due to the search
    '''

    name = 'list'

    def page_enter(self, ctx):
        ctx.locals.doclist = []
        ctx.add_session_vars('doclist')
    
    def page_process(self,ctx):
        if ctx.req_equals('detail'):
            ctx.set_page('detail')
        elif ctx.req_equals('recherche'):
            container = getContainer()
            for result in
container.searchContains('title',ctx.locals.title):
                ctx.locals.doclist.append(result)
            if len(ctx.locals.doclist)<1 :
                ctx.locals.error = "No document found"
                ctx.set_page('error')
            else :
                ctx.add_session_vars('doclist')
                
    def page_display(self,ctx):
        ctx.load_template('headers.html').to_html(ctx)
        ctx.load_template('footer.html').to_html(ctx)   
        ctx.run_template('list.html')
