How to config a hint for rich:autocomplete?

[edilmar]

Hi,

I use RF4.0.0-Final, with rich:autocomplete. Then, I would like to configure a hint to explain something for this field.

I tried to use like this code:

<a title="Explanation...">

    <rich:autocomplete id="ProprietarioFil_cidade" value="#{proprietarioFil.entity.cidade}"

                                            mode="cachedAjax" minChars="2" showButton="true"

                                            autocompleteMethod="#{proprietarioFil.cidadeLookup}"

                                            inputClass="autocompleteWidthDefault"

                                            readonly="false" required="false" requiredMessage="">

        <f:converter converterId="cidadeConverter"/>

    </rich:autocomplete>

</a>

but the resulting layout is not so good, it appears some spaces between this field and row above:

If I delete the <a title...>, the resulting layout becomes right:

Is there other way to implement a hint/explanation for this field. For example, a4j:commandButton has the title property that works fine for this goal.
