Jpivot issues in Pentaho 5.x CE

Hi,

I have several issues with the old, but reliable jpivot in Pentaho 5.x biserver.

My context is a Pentaho 5.2 CE biserver fresh installation

• Issue 1:I'm creating a new jpivot analysis and when I click the 'save as' button I get the message:

• Issue 2: Sometimes the Biserver 'save' and 'save as' buttons doesn't appear in jpivot, so the user is unable to save their analysis. Sometimes, deleting browser cache or rebooting biserver solves the problem.

I detected this issues since 5.0 release. I hoped it was solved in 5.2.

Any idea,

thanks.
