I've got a parent search-list-form showing all records of content-item (parents). Every (parent)Row contains a button(icon) to show a list of child-records for the specific parent. The child-list works fine and is showing and filtering OK. Only when I hit the cancel-button to return to parent-search-list-for I encounter a white "invalid token-message" screen.
I also have a button to edit-content-form in parent-list and add-child-content-form in parent list. When I click on these buttons and return by "cancel"-button from the content-forms it works fine, the parent-search-and-list-form is shown OK. Only when I return from child-list by "cancel"-button the token-error appears...
Thanks for responding. In my parent search-list-form each row of my list contains an icon-field. This icon is of "List & Search"-type which is linked by the (+) behind this option, to the child-list and corresponding menu-entry, this works fine, the child-list is OK and working (filtering etc.).
In my child-list I cancel by using a cancel (submit) button (task: cancel) in the search-part above the list-rows.
This problem still occurs, in every new list&search form I create. Maybe I'm doing something wrong, I've added a detailed screenprint-composition of the workflow and settings. Maybe this helps finding a solution....
I am not sure if the Cancel button would work in a search list view.
I think ( I might be wrong ) the cancel button behavior works in a form view only, where the URL that you got to the form from is being tracked. In your situation, you get to the child search list using a standard view link with URL variables and so CANCEL button has no info where to get back.
