Hi Lin,
The DataSource node,u have bound to the Interactive form is not initialized .Initialize the DataSource node in wdDoInit method.
e.g
InvoiceDetail detail = new InvoiceDetail();
wdContext.nodeInvoiceDetail().bind(detail);
Just check the above, if it works.
It could also be a Cardinality issue. If the above doesn't work make the cardinality as 1..n and also make sure that u need to give values in the pdf.
If you have bound  the datasource property of the interactive form UI element to a node,make sure that it should not be null,you need to fill data in the fields and try to display the output.
Hope this helps.
