'children' of undefined

[gazouweb]

Hi,

I use datatables with ajax and server side, but when I click on expand, I get an error

Uncaught TypeError: Cannot read property 'children' of undefined

Hi,
According to your description, I guess the data of the row you clicked is undefined, so I suggest you to check the data. You can also check my demo for the columns setting, the column 0 will handle the children property.

Good luck.
