WAD: Add variable to a called javascript function on button group item

Question

Hi All,
I need your expertise regarding the following problem:
To increase performance, I've decided to hide all analysis tables. To set these tables to visible, there is a button to switch the state for each table.
Because this function is needed for each table, the function has two parameters for the analysis item name and the new state.
Unfortunately, I get an useless error message after calling the function.
The function in script item looks like
function switchTable(itemName, newState)
The function is started by a button of a button group item as javascript and the following script function
switchTable('ANALYSIS_ITEM_1', 'VISIBLE')
If I enter a without parameters, that will call the function with these parameters, it works.
But if i try this directly from the script function in the button parameters, the function will be called correctly, but an error occurs and the analysis item wasn't displayed or the sendCommand wasn't processed completely.
I hope there is a way to call javascripts by a button with variables, otherwise I would have to create many functions with only an other item_ref.
Many thanks in advance and points of course for any help.
Regards,
Tobias

One short note:
It's possible to trigger the same function by an html input form button with onlick switchTable('ANALYSIS_ITEM_1', 'VISIBLE')
and this works.
Has anyone an idea what's the problem with a normal button item of the button group item?
Another possibility is a menu item. The functions were called, but errors were shown.
