Using a field hierarchy for selecting checkboxes?

Question

I have a bunch of checkboxes in a PDF that are dynamically added to the PDF during its creation process. Each checkbox is a cell in a table, and I do not know the number of rows or columns that will be in the PDF beforehand. What we are trying to do is add a header row to the table that allows the users to select/unselect all the check boxes in a column at once. I figured I could use the field name hierarchy approach to select/unselect all the checkboxes as long as I named them appropriately but I appear to be missing something.
Take for example this table (assume [] denotes where a checkbox will go):
Title
Category 1
Category 2
[check.global.category1]
[check.global.category2]
Some Product
[check.category1.cell1]
[check.category2.cell1]
Another Product
[check.category1.cell2]
[check.category2.cell2]
What I would like to do is add a JavaScript call so that when check.global.category1 is clicked I could add something like this to the click event:
var field = getField("check.category1");
field.checkThisBox() //or checkThisBox(false);
And that would toggle all the check boxes in the Category 1 column. However, that does not appear to work. Is there another mechanism to do this, or some way I can loop over all the check boxes that belong to the same hierarchy? I know this approach works with buttons and text fields but checkboxes appear to be different.

I found the answer. To get all the checkboxes use getArray() after calling getField.
