RequestCycle access without injecting
Hi
Is there any way to get hold of the RequestCycle in tapestry 4.0.x without injecting it ie some static utility that can provide it. Basically I think there is a bug with tables in that if you click a column heading to sort the column the table values are sorted in the rewind. This means that if you have a checkbox which on rewind records which rows are selected however when the rewind of the checkbox value occurs the values have been sorted so you cannot find the item via PrimaryKeyConverter and I don’t want to provide a Collection with all the results as this is a search so could be large.
So I’ve tracked it down to BasicTableModelWrap.getCurrentPageRows so I was thinking that if I could implement my own TableSortingState that could hold ‘current’ and ‘future’(sorting info for the render) sorting info and if I could workout there that we’re ‘rewinding’ then use the ‘current’ sorting info and only update the current sorting info when we’re rendering.
Any help would be greatly appreciated.
Howard

Hi
Thanks for the advice but I've found that moving the TableColumns component below the TableRows in the .html fixed the issue. The sort still occurs in the rewind phase but after the rewind of the rows so the checkbox can get the row from the current page data.

Why not make your ITableSortingState a service and inject IRequestCycle to that?
