[#3837] - Empty String Values in Input Control causes Exception

After much back and forth with Jaspersoft Support, it appears they are unwilling to fix their faulty server product. As such the only viable option here is to look at getting the client fixed to work around errors that occur here.

Details of the issue -

When retrieving the input controls associated with a report object in Japsersoft Mobile, it send a packet / request similar to below -

POST /jasperserver-pro/rest_v2/reports/reports/Sales_Report/inputControls HTTP/1.1
Authorization: Basic amFzcGVyYWRtaW58b3JnYW5pemF0aW9uMTpqYXNwZXJhZG1pbg==
Connection: close
Accept: application/xml, text/xml, application/*+xml
Content-Type: application/xml
User-Agent: Dalvik/1.6.0 (Linux; U; Android 4.4.2; VirtualBox Build/KOT49H)
Host: it-cameron-vm2:8080
Accept-Encoding: gzip
Cookie: userLocale=en_AU; JSESSIONID=189DC4993407F70775C1BF499932B260
Content-Length: 19

If the input controls requested contain a multi-select input control, where one of the values is an empty string (""), it causes a server side exception. Similar to the below -

2014-04-10 10:35:28,660 ERROR GenericExceptionMapper,http-80-3:42 - Unexpected error occurs
javax.ws.rs.WebApplicationException: javax.xml.bind.UnmarshalException

Feedback form Jaspersoft Support is this is not a problem with the server, but instead the Jaspersoft Mobile for Android application. The advice they have given me (I'm not sure who they expect me to fix this, but anyway) is as follows -

Just to give you some update on this. I have been checking on your URL and the packet. It appears a bit weird though.
If it's for the "List Input Control Structure", only the GET method can be used.
If it's for the "List Input Control Values", also only the GET method can be used.
On the other hand, if it's for "Set Input Control Values", this operation only supports the POST. However the URL doesn't look right. It's supposed to be in the form of http://:/jasperserver[-pro]/rest_v2/reports/path/to/report/inputControls/;
;.../values/.
Can you please let me know which operation you are doing for this particular packet?

I'm not sure what JS support is going on about here, I've looked at the information requested by the normal Jaspersoft Web interface, and it's doing mainly the same thing, the only major difference is it's requesting the response in JSON instead of XML.

So, short term fix, could this App get updated to get input controls in JSON instead of XML?
