[Building Sakai] Problems with sferyx in sakai 2.8

[Angel Nueda Lozano]

Hello everyone,

We are migrating to Sakai 2.8 and have encountered a problem we do not 
know how to fix it.
We cannot make the sferyx editor in melete 2.7.2 works well with this 
version of sakai. However, the same version of melete works well in 
sakai 2.6.

For example, we edit content and add a new phrase. Click Save ... and 
still appears the text before, it has not saved anything.
We know that this is because the http requests coming from the applet 
haven't any session, but do not know why. So, pressing the button save 
the applet invokes the page 'save.jsp' and from there it's saved the 
html page and images. But we saw in logs that the user does not have 
permissions and this is because in the session no user is logged.

We have seen that there is a similar problem with webservices, which is 
solved by adding the parameter in sakai.properties:
session.parameter.allow = true, but does not solve our problem.

Someone can help us?

regards,
Angel
