Control referencing not working when passed to function

Hello,

I am working on a coach view that has a function in my inline javascript.  On my layout I have a text box whose control id is “newComment”.  In the On Change event I added this:  @addComment();

I had originally wrote the function without a parameter:
this.addComment = function() {

var myComment = this.ui.get("newComment").getText();

This seems to work just fine; when the function runs the value of myComment is whatever text was entered in the text box.  Later I decided to add a parameter to the function, like so:

 this.addComment = function(vaComment) {
...
}

so I updated my On Change event as well, to this:  @addComment(me.getText());

I expected the function to get a string containing the content of the text box by no matter what addressing style I use I get some sort of object that I think is the view, not a string.  

What am I doing wrong?  What is the correct syntax for passing the value of a control to a function in my inline javascript from that same control's events?

I have read your Control Addressing article many times and nothing I found there (and I have tried every variation) seems to work.

Please help!  Thanks!

- Dave

Hey Dave,

The @ notation is a shorthand way of calling a function without passing in parameters. When passing in parameters, try using this code:

me.ui.invoke(“addComment”, me.getText())

Here is an article to learn more about this function – http://support.salientprocess.com/docs/enterprise/bpmext.ui.View.html#invoke
