Getting data from hot table in shiny about rhandsontable

[jrowen]

I just pushed a bunch of updates, and your example appears to be working fine. Could you please pull down the latest version (0.0.2) and let me know if you are still running into errors?

Unfortunately I am getting the same Error:

Error: attempt to set 'colnames' on an object with less than two dimensions

Here is my session info

I'm running the same versions except it's on Linux and rstudio is v0.98.1103. Can you try using traceback to find the source of the error?

[jpmarindiaz]

I am not familiar with traceback, but I will try to take a look.
I also tried it in my linux machine and I get the same error.

[jpmarindiaz]

I was playing around and noticed that the error only shows up only when I use: useTypes = FALSE.
If I use rhandsontable(DF, selectCallback = TRUE) in the example above I don't see the colnames error anymore.

[jrowen]

The error might be coming from the function that creates an R data.frame
from the widget data. You could try to use debug(toR) to step through the
conversion and identify the problem. I'm still unable to reproduce the
error.

I just pushed some updates related to column and row add/removes. Previously, when editing columns and rows, I saw a message similar to the one you mentioned. Could you retest with this latest update and let me know if you are still running into problems? Thanks.

I'm going to close this issue, but please re-open if you are still seeing errors.
