-------------------------------
Resolution: Fixed
fixed in trunk
> Adding controls to page or container should replace existing control with the
> same name
> ---------------------------------------------------------------------------------------
>
> Key: CLK-666
> URL: https://issues.apache.org/jira/browse/CLK-666
> Project: Click
> Issue Type: Improvement
> Components: core
> Affects Versions: 2.1.0
> Reporter: Bob Schellink
> Assignee: Bob Schellink
> Fix For: 2.2.0
>
>
> When adding controls, Click throws an exception if the Page or Container
> already contains a control with the same name. Page and Panel models behave
> similarly.
> This behavior protects users from accidentally adding controls with the same
> name, but at the same time doesn't work well for stateful pages where
> existing controls should be replaced.
> The proposed change is to *not* throw an exception and simply replace the
> existing control or model object.
