ViewNotFound while Ajax and Pyramids

问题

I'm using Pyramid and got a strange issue. I do an ajax request AR in view A. If the request is done, the user is redirected to view B. If the user goes back to A, the ajax request AR will fail, because pyramid does not find any view for the request.

If someone needs code, I'll post it ;-)

Thx & Greetings Tobias

Edit:

Head out of view not found in view.py

# 404 page
@notfound_view_config(renderer='templates/404.pt')
def notfound(self):
    """
    View configuration for the 404 page.
    :return: dictionary with title and project name as well as a value, weather the user is logged in
    """
    logger('- - - - - - - - - - - -', '- - - - - - - - - - - -', '- - - - - - - - - - - -')
    logger('notfound', 'def', 'main in ' + str(self.request.method) + '-request')
....

And one example ajax-call

/**
 * TODO: some text
 * @param statement for sending
 * @param issue for sending
 */
this.sendNewStartStatement = function (statement, issue) {
    var csrfToken = $('#' + hiddenCSRFTokenId).val();
    $.ajax({
        url: 'ajax_set_new_start_statement',
        method: 'POST',
        data: {
            statement: statement, issue: issue
        },
        dataType: 'json',
        async: true,
        headers: {
            'X-CSRF-Token': csrfToken
        }
    }).done(function ajaxSendStartStatementDone(data) {
        new InteractionHandler().callbackIfDoneForSendNewStartStatement(data);
    }).fail(function ajaxSendStartStatementFail() {
        alert('fail in ajax 4');
        // canceled while debuging
    });
};
