Custom component ordering remove tags

[rbojo]

Hello,

I have developed a custom component and follow intructions here to include Tag's functionality.

https://docs.joomla.org/J3.x:Using_Tags_in_an_Extension

The only I don't use is "batch processing" section.

But when I do ordering in the admin list view tags are removed from new item position to previous position.

Any idea??

Thanks in advance!!

Regards.
