Multi-sorting

[guillim]

I have a 2 column array, with multiColumnSort: false

When I sort the first column, and then the second column several times, I have a strange bug. At first I have 100 rows, and the more I sort, the less row i have. see the pictures bellow:

after 3 sort, I end with less than 10 rows,

When there are a few rows left, the array header begins to jump on the other like you'll see on the picture.

Note that there are still 5 pages, so somehow it has to be a display issue.

here my javascript console:

Any idea to troubleshoot this ? I went through all the question but couldn't find any soutions.

I noticed that if I sort 100 times the first column, it works fine. only when I sort the second column problem shows up.
