Hello All!
I am using the CreateEventLink method of the ComponentResources class to
create a link to a delete event on my page called UserList using the
following:
"resources.createEventLink("delete", user.getUserId()).toURI();"
The UserList page uses datatables to create a list of user's data and a
delete link. When the delete link is clicked, the delete event is called on
the same page and everyone is happy.
The problem is the datatable goes back to the first page of records after a
user is deleted. For example, if I am on page 5 of my datatable, on the
UserList page, and I click delete it will stay on the Userlist page, but my
datatable will reset itself to the first page.
After some research I haved discovered that the fnStandingRedraw plugin from
datatables will fix this issue: http://datatables.net/plug-ins/api
Going through the documentation I have learned that I should use:
javaScriptSupport.addInitializerCall("fnStandingRedraw", "");
to call the following in js file via an Import notation:
Tapestry.Initializer.fnStandingRedraw = function(oSettings) {
//redraw to account for filtering and sorting
// concept here is that (for client side) there is a row got inserted at
the end (for an add)
// or when a record was modified it could be in the middle of the table
// that is probably not supposed to be there - due to filtering /
sorting
// so we need to re process filtering and sorting
// BUT - if it is server side - then this should be handled by the
server - so skip this step
if(oSettings.oFeatures.bServerSide === false){
var before = oSettings._iDisplayStart;
oSettings.oApi._fnReDraw(oSettings);
//iDisplayStart has been reset to zero - so lets change it back
oSettings._iDisplayStart = before;
oSettings.oApi._fnCalculateEnd(oSettings);
}
//draw the 'current' page
oSettings.oApi._fnDraw(oSettings);
};
However I get the error:
Uncaught TypeError: Cannot read property 'bServerSide' of undefined
