Regarding the use of AjaxFallbackDefaultDataTable

[Jeremy Lee <je...@nz1.ibm.com>]

Hi,

I have a Search Form along with a AjaxFallbackDefaultDataTable on a page
that I am trying to create. How it is supposed to work is as follows:

1. User accesses page (only search form is visible)
2. User enters search parameters and submits request
3. The page returns search results.  The page at this point should still
show the search form, and also now the results through the
AjaxFallbackDefaultDataTable.

The problem that I am having is as follows:

In the page constructor I add both the form and the
AjaxFallbackDefaultDataTable and then set the table to not be visible. 
However I am finding that the table makes the call to the data provider when
it is initially instantiated.  I only want it to make the call to the data
provider when the search request is made.

The following is the code that I am using in the constructor to add the
table.

SortableDataProvider dp = new ReconcileReportProvider(new
ReconcileReportManagerImpl());
reportTable = new AjaxFallbackDefaultDataTable("searchResults", columns, dp,
rows);
reportTable.setVisible(false);
add(reportTable);

I am not too sure if this is even the right way to go about it.  Any
guidance would be appreciated.

Cheers.

Hi Jeremy,

You can try this: in your constructor, instead of the DataTable, create
an EmptyPanel with the same ID. In the onSubmit for your search form,
create the DataTable and use replace() to replace the EmptyPanel.

Hope this helps.
