This package allows to work around problems/weaknesses in ``zope.formlib`` and the associated widgets in ``zope.app.form.browser``, described by "https://bugs.launchpad.net/zope3/+bug/528920" and "https://bugs.launchpad.net/zope3/+bug/528912". The package has been developed for Zope 2.10, will probably work for Zope 2.11 and is unlikely to work for very new Zope versions, because the widget code has been moved from ``zope.app.form`` to ``zope.formlib``. I may publish versions of this package for new Zope versions in the future. The package consists of various modules described below. To use the package in your application, you import some of its patch functions (mentioned below) and call them during the startup of your application. I hope that corresponding patches will sooner or later appear in the standard Zope code and make this package obsolete. form ---- Together with ``widget``, this module is destined to work around http://dev.plone.org/plone/ticket/10264 and https://bugs.launchpad.net/zope3/+bug/528920. ``zope.formlib`` distinguishes between widget related errors and other (more global) errors. If a widget itself detects a widget related error (usually because a restriction for the associated field fails), it sets its error condition. This error condition is usually used to highlight the widget containing an error and to provide information about this error. However, if the widget related error is not detected by the widget itself, the error is not associated with the widget and important information may be missing. The function ``patch_action()`` in module ``form`` enhances ``zope.formlib.form.Action`` by an additional method ``associate_errors_with_widgets`` and redefines its ``failure`` method to call it unless an explicit failure handler is specified. This provides for automatic error association with the widgets in the standard case. ``associate_errors_with_widgets`` tries to associate ``zope.app.form.interfaces.WidgetInputError`` with the corresponding widget. For this purpose, the widget must have a ``setWidgetInputError`` method. By default widgets lack this method. However ``widget.patch_widget()`` can be used to define it. Therefore, ``form.patch_action()`` and ``widget.patch_widget()`` are usually used together. widget ------ Together with ``form``, this module is destined to work around http://dev.plone.org/plone/ticket/10264 and https://bugs.launchpad.net/zope3/+bug/528920. Its ``patch_widget()`` enhances ``zope.app.form.browser.widget.BrowserWidget`` (the base class for ``zope.app.form`` widgets) by defining the method ``setWidgetInputError``. The method allows external code to set an error condition on the widget. ``setWidgetInputError`` is used by the error handling implemented by the ``form`` module. Therefore, ``widget.patch_widget()`` is usually used together with ``form.patch_action()``. multiselection -------------- This module is destined to work around http://dev.plone.org/plone/ticket/10267 and https://bugs.launchpad.net/zope3/+bug/528912. Its ``patch_OrderedMultiSelectWidget()`` fixes ``zope.app.form.browser.itemswidgets.OrderedMultiSelectWidget``. Version history --------------- 2.0 Python 3 compatibility
