Temporary tables in forms

Using temporary tables in forms requires the use of the .setTmpData() method.

For example:

The temporary table data is populated in a static class method (running server side), which is called from the form and returns the populated table. We could populate a form-level buffer with the temporary data if needed, or else just call the populating method directly from the setTmpData() call as shown below.

In the form datasource init(), we use .setTmpData() to instruct the datasource query to use our temporary table. Our datasource name in this example is TempTable.

public void init()
{
    super(); 
    TempTable.setTmpData(tmpTableClass::populateTmpData());
}
