Hi all,
I'm developing an infopath form that has a dropdown where I configured a call to a WCF service using the dropdown rules.
In my environment there aren't problems, but in the production environment the first call to WCF service fails, from the second all works fine.
The form is rendered in the web in a sharepoint form library.
The error tells only that there was an error during retrieving data.
I added a log to WCF service at the start and the end of the method that the dropdown calls, but there aren't errors and the mothod is executed from the beginning to the end.
I increased the timeout in sharepoint central administration under Configure InfoPath Forms Services (Default data connection timeout and Maximum data connection timeout).
Any ideas?
Thanks for help!
Massimo
