InfoPath 2010 and REST web services, custom code button firing twice and second click fires error

The_Muns — Mon, 10 Feb 2014 08:12:53 GMT

Hi,

I have two supposing simple issues which I'm having problems correcting.

If a add a button to the form and write some custom code (See below) to submit some data via a REST Web Service data connection. The code runs but somehow fires the URL twice to the web service.

I've also recreated similar functionality using Rules on a button and some concat formulas and exactly the same thing happens when I the run the data using the Query Data Action, it fires the URL twice at the web service.

How can I stop this.

Secondly, if I use the custom code route, it work correctly the first time it pressed except for the double fire issue, but the second time I click the button the InfoPath internal system throws up an issue. See screen shot below.

Any help would be appreciated.
