Slawo, I suspect this is related to another case that I've been working on that isn't available in the current RC2 build. If you could answer a few questions it would help to determine if what you are seeing is related.
1. Have you run any previous version of PDI/Instaview before the installed version?
On the startup of the Instaview plugin, we create a shared connection that the templates make use of. However, before that shared connection was only being created if it did not already exist. By default, that connection was setting the port to connect on to 50000. The new installer is installing it's own version of MonetDB to the pentaho install folder and setting it to run on 50006. So, as you can imagine, if you have run this before the shared connection was created on port 50000 and now that you have run the installer it expects the port to bo 50006 but since we don't overwrite the shared connection if it already exists, then we have a conflict.
2. if you open the ~/.kettle/shared.xml file and look for the AgileBI connection, do you see the port setting set to 50000?
there are 2 different xml tags to look at <port>50000</port> and <attribute><code>PORT_NUMBER</code><attribute>50000</attribute></attribute>
2a. if yes to #2: if you either delete that shared connection from the shared.xml file or or update the port settings to 50006 and restart the application, does it work?
Assign this case back to me with your answers, please.
