Hi ALL!

I've a page where use tags rich:effect to show/hide some part of the page. Below is a code snippet:

...
                     <rich:effect name="show_audience_grp" for="#{rich:clientId('audience_grp')}" type="BlindDown"/>
                        <rich:effect name="hide_audience_grp" for="#{rich:clientId('audience_grp')}" type="BlindUp" />
                        <rich:effect name="show_audience_cli" for="#{rich:clientId('audience_cli')}" type="BlindDown" />
                        <rich:effect name="hide_audience_cli" for="#{rich:clientId('audience_cli')}" type="BlindUp" />
                        <script type="text/javascript">//<![CDATA[
                            function displayAudiencePanel() {
                                var audience_type = #{rich:element('audience_type')}.value;
                                if (audience_type == 'CLIENT_GROUPS') {
                                    hide_audience_cli();
                                    show_audience_grp();
                                } else {
                                    hide_audience_grp();
                                    show_audience_cli();
                                }
                            }
                        //]]></script>
                        <h:selectOneMenu id="audience_type" value="#{msgHome.instance.audienceType}" onchange="javascript:displayAudiencePanel()" style="margin-bottom: 5px">
                            <s:convertEnum />
                            <s:enumItem enumValue="CLIENT_GROUPS" label="Client groups" />
                            <s:enumItem enumValue="CLIENTS" label="Clients" />
                        </h:selectOneMenu>
...

The code works fine in FireFox3 but not in Google Chrome or Opera.

When the page is loading I can see following error in error console of Google Chrome:

Uncaught ReferenceError: params is not defined

the error in Opera is:

JavaScript - http://127.0.0.1:8080/cat/messages/edit.html?id=4454&l=3&cid=46
Inline script thread
Error:
name: ReferenceError
message: Statement on line 1: Undefined variable: params
stacktrace: n/a; see  opera:config#UserPrefs|Exceptions Have Stacktrace

Can anybody give me advice how can I fix the issue?
I use RF 3.3.3.Final.

Thanks in advice.
