[jira] [Commented] (ISIS-560) When invoking an action, drop downs get cleared (in the UI) if there is a validation error, but the underlying model is set.

["Dan Haywood (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ISIS-560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13799874#comment-13799874 ] 

Dan Haywood commented on ISIS-560:
----------------------------------

As a partial fix, remove the Wicket setRequired, and instead rely on Isis' validation.

The side-effect of this is that the error appears in the form's feedback panel, not the parameter's feedback panel.

Hopefully ISIS-570 will more fully address this issue.

> This allows the user to hit OK and complete the object even though it seems that there is no value for those drop downs.
> for example:
> ToDoItems#newToDo(...)
> leave description blank;
> the category/subcategory are blank, but can complete (so they actually have values)
