Hi Thorsten, Can you show us some code (html and java) - perhaps as a github gist or similar? It’s not 100% clear to me what you are asking.
For page-unique ids, simply let wicket render the components and call setOutputMarkupId(true). If you want to control the ids yourself, cal setMarkupId(String id). Regarding the “headers” attribute: simply override onComponentTag in your table component, and change the headers attribute as you want; This way you don’t have to add an AttributeModifier, and don’t have to think of it.

The markup uses "id" and "headers" attributes, but with static values in the markup and with multiple instances of the table this is wrong of course, because ids need to be unique across a whole page, not only across a single table. In terms of Wicket the tables itself are rendered using IDataView with the table markup coming from a panel. The rows of the table are rendered using IDataView as well and each cell is e.g. a simple Label component. With each cell being a Label, I could add an AttributeReplacer or sich replacing the static "headers" from the markup with some generic value. But I would like to avoid the need to think of this for every table and a more generic approach. Additionally, the "thead" of the table with the column headers and ids is no wicket component currently, but I would need to make each column header one to be able to change the "id" using an AttributeReplacer as well. So is there some easy, somewhat clean way to change the markup of a component instance before it is used for rendering and produce some page unique ids in it? Thanks!
