[AC-472] Multipart HTTP request composed with errors

I send HTTP multipart request with te following code: thefile=Titanium.Filesystem.getFile(this.filepath_to_upload); postdata={ name: this.guid, createDT:this.createDT+"", session_length:this.session_length+"", device_model:Titanium.Platform.getModel(), device_manufacturer:Titanium.Platform.getManufacturer(), device_osname:Titanium.Platform.getOsname(), device_version:Titanium.Platform.getVersion(), device_locale:Titanium.Platform.getLocale(), result_type:2, //for fitness=0, for science=1, for fitness+science =2 debug:false, file: thefile }; client.open("POST", url); client.setRequestHeader( 'Authorization', 'Basic ' + Ti.Utils.base64encode(auth.username+':'+auth.password) ); client.setRequestHeader("enctype", "multipart/form-data"); client.send(postdata); And the app composes inclosed name tags in the request, for example: ---0Yp7DHdqG1dPhejcf_POatQ2DMYKnOxDBeC Content-Disposition: form-data; name="name Content-Type: ; charset=UTF-8 Content-Transfer-Encoding: 8bit 52959e65-8c74-c8c0-be18-90f047f5e9b6 ---0Yp7DHdqG1dPhejcf_POatQ2DMYKnOxDBeC Content-Disposition: form-data; name="device_locale Content-Type: ; charset=UTF-8 Content-Transfer-Encoding: 8bit en-US ---0Yp7DHdqG1dPhejcf_POatQ2DMYKnOxDBeC Content-Disposition: form-data; name="debug Content-Type: ; charset=UTF-8 Content-Transfer-Encoding: 8bit Only file field are formed correctly. This appear in all versions of Titanium SDK 5, but if fall back to version 4 or 3 - all works perfectly.
