1. What is the problem? Be very detailed.
I am trying to upload a form to use on ODK collect. My form is accepted on XLSForm Online but when I try and upload it on Aggregate I get the following error " Error: Problem with JavaRosa Parsing Form: org.opendatakit.aggregate.exception.ODKIncompleteSubmissionData: Javarosa failed to construct a FormDef. Is this an XForm definition?".
I have narrowed my error down to the "start-geopoint" type question. I currently have it in this format on my .xlsx form
This is likely because your Aggregate server pre-dates the addition of this feature. I now realize that the note in the documentation should also include a minimum Aggregate version and I have filed this as an issue here.
Since you are on AppEngine, the highest version of Aggregate that you can update to is v1.7.3 and I have verified that background geopoint works in it. This documentation page has instructions for upgrading Aggregate.
Oh wow, I'm really sorry, I just realized that the server I was testing on had some modifications. It looks like we have not yet released an Aggregate version that supports this feature. @ggalmazor, @yanokwa could one of you please do that? Thank you so much for pointing that out, @Michael_Rademeyer.
