Is a String the data type of a list when passed to the Controller from GSP?

Question

Is a String the data type of a list when passed to the Controller from GSP?

Within my Javascript code on the client side, I have constructed a List of Strings that appears in the Javascript console like this:

["No address provided.", "No telephone number provided."]

When I send this data to my Controller as one of the parameters from my GSP using an ajax call, the controller interprets it differently:

No address provided.,No telephone number provided.

It sees the list as a single string without the square brackets. Here is how I am passing the parameters:

<button id="save" onclick = "${remoteFunction(controller: 'customer', 
                                                action: 'saveModifiedIndividualRecord',
                                                params: '\'uniqueId=\' + uniqueId + \'&secondaryId=\' + secondaryId + \'&redIssuesRemoved=\' + removedRedIssues + \'&yellowIssuesRemoved=\' + removedYellowIssues')}"> Save </button>

Is there any way to ensure that the Controller recognizes the input as a List and not just a String?

Here is a suggestion for handling this in your controller:

Extract the removed red and yellow issues from the parameters by splitting them into arrays:
def redIssuesRemoved = params.redIssuesRemoved.tokenize(",")
def yellowIssuesRemoved = params.yellowIssuesRemoved.tokenize(",")

My assumption is that both red or yellow problems are included in your list of string parameters. Consider using def listOfRedIssue = params.list('redIssuesRemoved') to make it a List of either red or yellow issues.
