Thread:Project:Support desk/query categorymembers not working with cmcontinue

I don't know if this is the right place to place this question. If not excuse me and if possible suggest me where to place my question. I'm doing some tests to use api. I have developed some code. It works for long time, now it looks that something is changed and the cmcontinue parameters is returned not as title but as pageid. But if I pass it to contine the query, the query doesn't work correctly. Here you have an example

http://it.wikipedia.org/w/api.php?action=query&list=categorymembers&cmtitle=Categoria:Verona&format=xmlfm

             

and then

http://it.wikipedia.org/w/api.php?action=query&list=categorymembers&cmtitle=Categoria:Verona&format=xmlfm&cmcontinue=1358867

that should return me the subsequent categories is instead returning me

  <cm pageid="2951758" ns="0" title="Verona" /> <cm pageid="2262962" ns="0" title="Accademia di Agricoltura di Verona" /> <cm pageid="2262943" ns="0" title="Accademia Filarmonica di Verona" /> <cm pageid="2579584" ns="0" title="Campane alla Veronese" /> <cm pageid="2994436" ns="0" title="Canale Camuzzoni" /> <cm pageid="3140773" ns="0" title="Cappella Pellegrini (San Bernardino)" /> <cm pageid="2779175" ns="0" title="Carnevale di Verona" /> <cm pageid="3360979" ns="0" title="Chiese di Verona" /> <cm pageid="1358867" ns="0" title="Colle San Pietro" />  <categorymembers cmcontinue="2442453" /> </query-continue>

and as you can see it is not returning me the subsequent categories, but part of the previously returned categories. This happens with all the formats I tried: xmlfm, xml, jsonfm, json. I have tried to replace 1358867 with the title of the category and other attempts, but no improvements. Any hint to solve my problem? Thank you very much. Massimo
