Google App Inventor on Ubuntu

Symptoms

Through either Chrome or Firefox the codeblocks would not load and download the same file every time you click on the button inside App Inventor web site.

AppInventorForAndroidCodeblocks.jnlp

Firefox would not open with the Sun version of java even though it is designated as the default java (using the “update-java-alternative” command)

Cause

Firefox did not automatically map the java plugin to run.

Solution

Browse to the Sun java when prompted here:

/usr/lib/jvm/java-version-specific/bin/javaws

and then it will open!

CRM Data Migration Manager Errors Sign-in

Symptoms

Microsoft CRM Data Migration Manager gives an error when signing in when synchronizing the data.

• You must have the system administrator security role to use this tool
• An error occurred.
• No error, just takes you back to the sign in welcome screen

Cause

There are some prerequisite components that get installed as part of an update rollup (perhaps with UR6) that get used by a subsequent rollup, even though rollups are supposed to be cumulative.

Solution

Remove the DMM update rollup that is installed, install update rollup 6, and then install update rollup 7 or whatever is applicable to the environment.  In my testing I was not prompted to reboot.

Scribe DBLOOKUP More Stable Alternative

Symptoms
An integration had an issue where the DBLOOKUP was not reliably, i.e., inconsistently, returning a customer ID value that I knew was in the database.
Cause
Scribe does not assign variables in an entirely predictive way, not necessarily when invoked.  Intuitively, you would think that if a value is used in a formula and if the process doesn’t know the answer it will look it up, but sometimes it does not.
Solution
Add a seek step to lookup the value, and then create a ‘target’ formula to create a variable from the desired field in the seek.  That variable should replace wherever the variable was formerly used the DBLOOKUP
