Note
If you created your project with a version of the library less than 4.3.1 add the following line in the on_page_loaded event handler in the task’s client module:
task.old_forms = true;
For libraries with versions 4.3, clear the code of client modules of catalogs and journals and replace client module of the task with the corresponding code of the Demo application or the new project. Make an archive of the project before doing it.
