Re: [jira] Created: (BEEHIVE-1101) netui JSP tags should support dataSource "refs"

[Chad Schoettger <ch...@gmail.com>]

Hi Eddie,

I was wondering if you'd had much of a chance to look into this issue?
If not, would you mind if I took a look and posted a proposed solution
back to the dev list for discussion?  Assuming agreement on the dev
list for the solution I could also make the necessary code changes.

It's your bug, so I don't know if you've already looked into it or
have code ready to be commited -- if that's the case I'll look for
something else in the current set of open bugs.

  -- Thanks, Chad

> In 1.0.1, the NetUI JSP tags use a "dataSource" attribute to refer to data in a data bindable object.  For UI elements that are translated into HTML "input"s, the "dataSource" attribute is often bound to an action form.  For example:

This might look like:
>
>   <netui:textBox dataSource="ref:refBean.textProperty"/>

This would allow the creation of larger, reusable components that could be data bound to objects of different shapes rather than to a the shape of a single action form.
