So if I understood you correctly, its better using different faces from each 'module' interacting with other 'module' within same application or with another application altogether (its rather more important when they are using overlapping name prefixes). I guess we do not capture this aspect in the porting guide and perhaps worthwhile to mention it. Can you please check? </div></div></div></blockquote></div><br class=""></body></html>
