Subject [jira] [Commented] (TAP5-1527) BeanEditForm loses object found by onPrepare() during render
Date Tue, 14 Jun 2011 13:01:47 GMT

    [ https://issues.apache.org/jira/browse/TAP5-1527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13049167#comment-13049167

Geoff Callender commented on TAP5-1527:
---------------------------------------

I've modified http://jumpstart.doublenegative.com.au/jumpstart/examples/input/edit1/1 to work
around this bug - it now gets the object in setupRender if the object is null.

> Was fine in 5.1.0.5, discovered when upgrading to 5.2.5.
> Using a BeanEditForm to edit an object: onPrepare() is being called twice (!) during
the render phase, and then the object found in onPrepare() disappears!
> 	http://jumpstart.doublenegative.com.au/jumpstart/examples/input/edit1/1
> Yet, when you replace BeanEditForm with a Form around a BeanEditor, everything works
correctly: onPrepare() is called once during the render phase and the object doesn't disappear:
> 	http://jumpstart.doublenegative.com.au/jumpstart/examples/input/morecontroledit1/1
> You can see the java code is almost identical in the two examples but the result is different.
