Resetting textbox value to "" in inputcontrol but filter is not getting applied in rest call jasperserver.

[vlimkar]

I am working on customizing existing jasper input controls. Requirement is to show/hide textboxes on click of multiselect check box control. ex. If I am checking 5 checkboxes from multiselect checkboc then corrosponding 5 textboxes appear dynamically. This I have achieved so far but the issue is with rest call. When unchecking the checkbox, corrosponding textbox disappears and its value is reset to "" by using getElementsByTagName("input")[0].value ="" but still the rest call heppens with previous value in the textbox. Filtering the report with is not happening properly.

How to set the uri value of textbox to null/"" in inputControlState in jasperserver??
