Uploading multiple files yields identical datapaths

[kristoff...@gmail.com]

Hi

When trying to upload multiple files via fileInput("files", ..., multiple = TRUE) the input$files data frame contains identical entries in datapath for different input files, e.g:

                                          name                                   datapath

4 2012-03-07_kfsq120201_teg_rp0319_runid-1.rds /tmp/RtmpBNyxXI/a759a583afcd07c7dea87b0a/4

Looking the fileupload.R source it appears that the datapath filename is the length of (.files):

filename <- file.path(.dir, as.character(length(.files)))

Are some files uploaded simultaneously, so that the first (0) gets its own datapath, but the remaining four gets the same (4)?

Running shiny 0.5.0, and this is reproducible with different filetypes. Any ideas?

Bug confirmed. I'll check a fix in shortly. Thanks!

I checked in a fix, you can install it as usual with:

install.packages("devtools")  # unless you have it already

devtools::install_github("shiny", "rstudio")

Thanks for the report!

Thanks! Works for me as well now.

And thanks for shiny - it is a really nice and useful package!

Guys, any idea when this update will be pushed to cran?  Due to funky company rules, going through devtools is a bit of a pain.

Thanks as always.  I love shiny!

Very soon, thanks for your patience. We've been held up waiting on httpuv 1.0.6.3 to be allowed into CRAN but that was approved on Monday so we'll be pushing shiny ASAP.
