reset() method for a Grid
-------------------------
Key: TAPESTRY-2263
URL: https://issues.apache.org/jira/browse/TAPESTRY-2263
Project: Tapestry
Issue Type: Improvement
Components: tapestry-core
Affects Versions: 5.0.10
Reporter: Jesper Zedlitz
I have a couple of lists with identification numbers. The lists contain entries
that are displayed using a Grid. The page ShowEntries has a method
onActivate(int id) to get the id from the request. A getEntries() method in
that page returns the entries. When I load the page the first time via
/myapp/showentries/1 these methods are invoked:
onActivate
getEntries
GridDataSource.getAvailableRows
GridDataSource.prepare (entries 0-19, objects per page is 20)
GridDataSource.getAvailableRows (4x)
GridDataSource.getRowValue (n times)
on chaning to a different page of the table (the 3rd in this example)
onActivate
onActivate
getEntries
GridDataSource.getAvailableRows
GridDataSource.prepare 40-59
GridDataSource.getAvailableRows (4x)
GridDataSource.getRowValue (n times)
So far so good. Now I want to load a different list
/myapp/showentries/2
But the previous selected page of the table (and the sort column) is displayed
instead of the first page.
It would be nice to have a reset() method on the Grid to start the new request
on the first page with a defined sort column.
