I was referring to this signature:
def ajaxButton(text: NodeSeq, jsExp: JsExp, func: String => JsCmd,
attrs: (String, String)*): Elem
and not
def ajaxButton(text: NodeSeq, jsFunc: Call, func: () => JsCmd, attrs:
(String, String)*): Elem
jsExp will be called before sending the actual ajax. But this may be a
bit problematic if your jsExp sends the ajaxForm the ajax request is
processed asynchronously at js level meaning the the button ajax
request may be send before the actual ajax form processing is done.
I'm not sure if this fits your needs

The first solution I described involving hidden fields will definitely
work. I don't think you need to do 2 ajax calls (one for the form and
one for the button) but piggy back the button information into a
hidden field and only submit the form:
Perhaps something like:
<button onclick={(JqId("hidden_field_id") >> JqAttr("value", "add")) +
+ SHtml.submitAjaxForm(form_ID).toJsCmd}>blah</button>

Yes jsExp is being evaluated and its result is being sent to server.
Please open a defect for this inconsistency.
