# of parameters you can pass using AJAX

[NettlesD]

I have a weird problem with an AJAX form combined with a CFC.  Just to rule out any possibilities, is there a limit on the number of input fields you can pass to a CFC using AJAX?  I only ask because it appears when the entire form is filled out the page throws an error that the CFC can't be found.

Also, I'm noticing that 2 of the parameters are out of order (in red). Would that make a difference?  I'm also not sure why they are out of order when getting passed because they are not that way on the form.  Am I missing something here?

The fix is to set "setHTTPMethod("POST");" for the AJAX proxy.  By default, the proxy function "setHTTPMethod("method");"  is set to "GET" and 47 input fields with corresponding data is over the limit.  The proxy function, "setHTTPMethod("method");", must be set to "POST" to avoid this error.
