[jira] Commented: (TAPESTRY-1932) Extend PropertyModel to handle annotation tasks.

["Howard M. Lewis Ship (JIRA)" <de...@tapestry.apache.org>]

    [ https://issues.apache.org/jira/browse/TAPESTRY-1932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12571784#action_12571784 ] 

Howard M. Lewis Ship commented on TAPESTRY-1932:
------------------------------------------------

I've been of two minds on this, for instance, when I was working on adding support for @Width. It's a question of where logic should live (to avoid duplication).  Ultimately, support for @Width maybe wasn't implemented the correct way and that logic should be inside AbstractTextField rather than inside BeanModelSourceImpl/PropertyModelImpl.

> Oftentimes I have to work with beans that I do not have the source for.  These beans come out of a library that is shared amongst other apps or out of a third party library.  As such, annotating fields with the "Validate" annotation or the proposed "PropertyType" annotation (see TAPESTRY-1931) are not possible.
> What would be great is if the PropertyModel exposed these customizations via API additions.  Then, during model customization, one could do something similar to the following:
> model.add("some_text_property").addValidation("required")
> Or:
> model.add("some_text_property").setType("longtext")
