Am using 11.1.1.6, when i login to the Process workspace I am getting a blank page, It used to work well before. The error I get in the console is as follows:

One thing you might want to look at is the engine's BPM_CUBE_PROCESS table. I've had null pointer exceptions when logging into the Workspace that was caused by a problem with this table's STATUS column.
To see if this might be your issue, log into the database as DEV_SOAINFRA and run this query:
select processId,processName,status from bpm_cube_process;This will return a list of the BPM Projects that the Workspace is looking for that are active. If the table thinks it is active, the status is 1. If it is not then the status is -1.
If this is a development environment, get on Enterprise Manager and undeploy all your BPM projects. Run the above SQL query again. Every row returned should have a -1 status. If you see a row that has a status set to "1" then you have an issue that can be fixed. Run an UPDATE SQL query against the row and change the status from "1" to "-1".
This is obviously something you would not want to do in a production environment, but if this is your development environment it is something you should look into.
