Ressource not really deleted from JasperReports Server ?

Hello everyone,

I have a strange problem in JasperReports Server, in one report (reportA) I have some text fields and in an another report (reportB), I have a subreport that contains the reportA.

When I launched my reportB the first time, everything worked, I had the expected result.

But when I modified my reportA several times, at one moment my reportB didn't update his content.

So my reportB displays a content that doesn't exist anymore inside the JasperReports server as you can see on these images :

Is it possible that my older version of the report A is still on the JasperReports server ? I don't understand what could cause this behaviour.

Thanks for your help !
