Re: ajax request and reload the datview model

[Dariusz Wojtas <dw...@gmail.com>]

I have faced similar problem recently.
The solution was to modify your dataProvider parameters.
Instead of passing new dataProvider, playing with the constructors,
just load it with new properties.

Some pseudocode.


final ISortableDataProvider myDataProvider = ...
final DataView dataView = new DataView("dataView", myDataProvider) {
  ...
};

final WebMarkupContainer markupContainer = new ... {
   onBeforeRender() {
       // modified dataprovider will return different set of data
       myDataProvider.setParam(<someNewValue>);
   }
}
markupContainer.add(dataView);


After I undetstood this - life became muuuch easier in many scenarios.
This may be onvoked in many places. After pressing a button, reloading
fragment of the page with ajax, ...

Best regards,
