------------------------------------

I hope your patch works as this bug has been preventing us from using t5.2 for months.  I'm pretty surprised this has gone so long without being fixed.  This bug has also been reported here TAP5-1051 and a small thread here: http://old.nabble.com/T5.2.0-SNAPHOT%3A-newbie-exceptions-submitting-form-with-BeanEditor-ts27947909.html#a27950914 .

> I'm getting exception in my app:
> Render queue error in SetupRender[Details:itemeditor]:   Bean editor model for org.apache.tapestry5.integration.app7.data.Item already contains a property model for property 'displayName'.
> Not sure if this is a bug or my misunderstanding of some T5 concepts. 
> Here is my use case:
> I have 'Index' page displaying a list of items in a grid. Every row in the grid has an 'Edit' link (pagelink) that leads to 'Details' page where I can edit selected item using BeanEditor component. After clicking Submit application should redirect me back to 'Index' page where I can see the list with updated item. I may want to click 'Edit' once again and repeat the use case, but now at this place I get an exception I noted above.
> Here's my 'Item' class:
> package org.apache.tapestry5.integration.app7.data;
> public class Item {
> 	private int id;
> 	
> 	public Item(int id) {
> 		this.id = id;
> 	}
> 	public int getId() {
> 		return id;
> 	}
> 	
> 	public void setId(int id) {
> 		this.id = id;
> 	}
> 	public String getDisplayName() {
> 		return "Item #" + id;
> 	}
> }
> and a part of beaneditor markup on Details page:
> 				<t:beaneditor t:id="itemEditor" object="item" add="displayName"
> 					submitLabel="Apply Edit">
> You can see I declare new property (displayName) for the Item bean model. This works fine the first time I navigate to the Details page, but fails on the second time.
> To illustrate the exception I wrote a simple test case (see attachment). I took app6 integration test of tapestry-core tests as a reference (from trunk version on github) and implemented the test case in a new test application (app7). 
> Hope this will help to understand the issue.
