Refreshing the pages [message #985818]

Hi,

I have an outline based application with a lot of table pages and some nodes that show a form.

If a table pages is shown for the first time it loads all the data and shows it. If you to another page and back to the first page, tha data is is not reloaded automaically. Only if I hit the standard refresh button the data gets reloaded.

Now I have a Page that shows one form (that is created and shown with the method startModify()). Loading the data on this form costs a lot of time so I only do this once.

But sometimes the user also wants to refresh this page. How can I make it that also this page reacts on the standard refresh button?

Regards Bertin

I am not sure to understand what you want to do:

1) Not reloading a page after modification.
The code that open a form for modification looks like this (execAction() function of the Menu class)

@Override
protected void execAction() throws ProcessingException {
  FilmForm form = new FilmForm();
  form.setFilmId(getFilmIdColumn().getSelectedValue());
  form.startModify();
  form.waitFor();
  if (form.isFormStored()) {
    reloadPage();
  }
}

you can remove the call to reloadPage(), and your table is not reloaded when the user save the form.

2) Notification that the refresh button was called.
When the user press F5 or click on relaod, this will call:
AbstractPage#reloadPage()
that will call AbstractPageWithTable#loadChildren()
that will call AbstractPageWithTable#loadTableDataImpl()
that will call AbstractPageWithTable#execPopulateTable()
that will call AbstractPageWithTable#execLoadTableData(SearchFilter)

The last 2 functions can be overriden so you can implement what you want (like updating a form).

I hope its help. If not do not hesitate to provide more information on your use case...
