                 Key: MYFACES-4636

*Steps to reproduce:*
 - create xhtml with f:param and f:ajax onevent like this:

 
{code:html}
<h:form prependId="false">
    <h:commandLink action="#{sampleBean.doAction}">
        <h:outputText value="Click Me!"/>
        <f:param name="var1" value="NEW VALUE"/>
        <f:ajax event="click"
                execute="@this"
                onevent="testJs">
        </f:ajax>
    </h:commandLink>
</h:form>

<script>
    //<![CDATA[
    function testJs(data) {
        if (data.status === 'success') {
            alert("Success click")
        }
    }
    //]]>
</script>
{code}
 
 - click on "Click me"
 - get an error in the console: "{color:red}Uncaught SyntaxError: Unexpected 
token ':' (at index.xhtml:9:868){color}"


*The reason: *

Generated page code by M7 build:

{code:javascript}
jsf.util.chain(this, 
event,function(event){myfaces.ab(this,event,'click','j_id_i','',{'onevent':testJs,'var1':'NEW
 VALUE'})}); return false;
{code}


Generated page code by M8 build with {*}bad JS{*}:

{code:javascript}
jsf.util.chain(this, 
event,function(event){myfaces.ab(this,event,'click','j_id_i','',{'onevent':testJsparams:{'var1':'NEW
 VALUE'}})}); return false;
{code}

*I've attached an archive with an example.*
