'Data Model' can't be saved in BI Publisher v11.1.1.3.0
I am new to using BI Publisher. I met following problem when I using it.
Environment: Windows 2003 server R2, IE8, Physical Memory 4G, Oracle DB 11.2.0.
I downloaded Oracle Business Intelligence from web site, and installed it according to the installation document.
After logined in BI publisher using URL: http://computername:9704/xmlpserver/, I could create and save report(using an existing data model), but I couldn't save new created data model or changed existing data model. The 'Save As' dialog wasn't closed by clicking 'Save' button, and there was a message saying 'Saving ...' on the main page, never disappearing if I do nothing.
