["Martin Grigorov (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/WICKET-5421?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Martin Grigorov resolved WICKET-5421.
-------------------------------------

    Resolution: Incomplete

The exception is thrown when a component is not found in the page. Usually it is an error in the application itself.
If you are able to provide a quickstart app that demonstrates the problem then please attach it and we will debug it.

>                 URL: https://issues.apache.org/jira/browse/WICKET-5421
>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket
>    Affects Versions: 6.7.0
>         Environment: OS: Linux
> Development tools: Eclipse, Glassfish, Java 7, Spring, MyBatis.

> While moving between pages, sometime I get the ComponentNotFoundException.
> The error message is like this:
> org.apache.wicket.core.request.handler.ComponentNotFoundException: Could not find component 'form1:dataViewScanManagementProjectDetail:3:lnkScanManagementPackageDetail' on page 'class jp.ne.hoge.hogehoge.player.companymanagement.CompanyManagementPage
> In this case, I was about to move from a page named "CompanyManagementPage" to a page named "ScanManagementPackageDetailPage."
> Of course a Link component named "lnkScanManagementPackageDetail" exists on the "ScanManagementPackageDetailPage," but the Wicket framework sometimes refers to the previous page; the Link component does not exist on the "CompanyManagementPage" and that is why the ComponentNotFoundException occurred.
> I really am not sure why the Wicket framework sometimes behaves like that, and if you have any idea, please let me know. Any suggestions will be appreciated. Thank you.
