[x] clicking on "choose from existing one" to select an existing context shows a blank page: this then works when uploading at least a file and clicking on save.
[x] when uploading file (samples/win_evtx/system.evtx, ~1mb) upload works but the upload dialog do not close: only way to show the data is to refresh the page.
[x] uploading big file (samples/win_evtx/security_big_sample.evtx, ~35mb) does not work: probably headers are sent wrong if sent in chunk, check .net UI
