Is there any way to get rid of the autosave notification on switching fields

[Dawn]

I'm using ScriptRunner to auto populate the description field in Jira Datacenter based on issue type, however the image shows the pop up that comes up whenever a different issue type is picked (for example Bug to Task). While it is useful overall, in this case the user would prefer to now have this show. 

Example:

Here is a slightly modified version of the script I'm using:

def desc = getFieldById("description")

if (issueContext.issueType.name == "Bug") {
def descValue = """
This is a bug

""".replaceAll(/ /, '')
desc.setFormValue(descValue) 
}

if (issueContext.issueType.name == "Task") {
def descValue = """
This is a task

""".replaceAll(/ /, '')
desc.setFormValue(descValue)
}

Solution if anyone else is looking for it: Moving the script from the initialiser to the field settings in behaviors fixed it.
