> Key: WICKET-3387
> URL: https://issues.apache.org/jira/browse/WICKET-3387
> Project: Wicket
> Issue Type: Bug
> Components: wicket-extensions
> Affects Versions: 1.5-RC1
> Environment: Wicket in development mode
> Reporter: Bertrand Guay-Paquet
> Assignee: Igor Vaynberg
> Priority: Minor
> Fix For: 1.5-RC2
>
>
> With Wicket in development mode, using a
> org.apache.wicket.extensions.markup.html.repeater.data.table.DataTable
> produces 2 warnings on each page view (at least with non-empty table data) :
> WARN - AbstractRepeater - Child component of repeater
> org.apache.wicket.extensions.markup.html.repeater.data.table.DataTable$ToolbarsContainer:topToolbars
> has a non-safe child id of $toolbar$0. Safe child ids must be composed of
> digits only.
> WARN - AbstractRepeater - Child component of repeater
> org.apache.wicket.extensions.markup.html.repeater.data.table.DataTable$ToolbarsContainer:bottomToolbars
> has a non-safe child id of $toolbar$2. Safe child ids must be composed of
> digits only.
> Wicket 1.4.15 did not have this behaviour.
> org.apache.wicket.extensions.markup.html.repeater.data.table.AbstractToolbar
> line 48 is the producer of the guilty "unsafe" child id.
> (is the usage of a static counter to produce unique ids safe considering
> multiple pages could be creating AbstractToolbars at the same time?)
> Steps to reproduce :
> Run the wicket-examples in development mode and navigate to
> http://localhost:8080/repeater/wicket/bookmarkable/org.apache.wicket.examples.repeater.DataTablePage.
