Steps to reproduce the issue

Hello,

I have been Working with Joomla from 3 years.

Now i get stuck with new Issue, unable to save a attribs param which is added through custom plug-in.

My requirement is to add couple of params through Plug-in and base on some condition i have to remove one param from these list.

I have used joomla $form api to do this but it didn't work.

code:

$form->loadFile('params', false);
if(!in_array($data->catid,$mappedCategories))
{
$form->removeField("mappedCategory","attribs");
}

Expected result

Saving mappedCategory field to attribs list

Actual result

mappedCategory param removed from database when i save the article

System information (as much as possible)
