I would like to be able to invoke a server side method that would go do a task based on parameters passed to it and return a string (or object) from a method (client side javascript) that I would bind to a form field in the Field Event - onClick . For example, on click , gather the values in three fields on the form (I have done this much so far) and pass those values to the server side method where it goes off and talks to another application and returns the result to the javascript where I can then display that result.
I have searched through the examples, scoured the API course manual I have and can't find an example of how to pull this off. Is it possible? Seems like with all the communication back tothe server that the form does, it ought to be doable....I'm just having a hard time getting my head around how to do...what method is available at that client side environment to do it.
A simple example would be sufficient to get me passed this mental block.
Thanks.

Hi;
In the Innovator Programmers Guide there is a short section that gives a partial example on how to have a client-side method call a server-side method. Below is an excerpt from the Programmers Guide. What's missing in the example is the code for the server-side method itself. I don't have an example with me (I am travelling), but I do have one at home that I will post in the next day or two.
7.12 Apply a Generic Method
You want to write Generic Methods that can be used as subroutines for other
Methods.
Technique
Use the
Innovator.applyMethod() method to apply Generic Methods. The followingexamples assume a server-side method named "Reverse String" exists, and that it
returns a result item containing the reversed contents of the <string> tag.
JavaScript
var inn = this.newInnovator();
var results = inn.applyMethod("Reverse String", "<string>abc</string>");
return results.getResult(); // returns "cba"

As promised, below is a VB server method for "Reverse String":
Dim myInnov As Innovator = Me.newInnovator()
Dim
inString As String = Me.getProperty("string")Dim
outString As String = StrReverse(inString)Return
(myInnov.newResult(outString))
