One of the teams at
Tableau is called the Extensions team internally. They are releasing a new feature to connect
data to Tableau and are in the 2018.2 Beta 2 release of Tableau.
I listened to their
online training on this and they admitted to a bug they had with their original
beta release.
The original
manifest XML we posted on github for our fiirst beta had a typo in it.
Check out this one
line:
<manifest
xmlns="http://wwww.tableau.com/xml/extension_manifest"
manifest-version="0.1">
Do you see the
typo? There are 4 ws in the url.
It should have been
<manifest
xmlns="http://www.tableau.com/xml/extension_manifest"
manifest-version="0.1">
When
troubleshooting, this was pretty easy to find (but embarrassing). It is also easy to fix - just delete that
extra w. And anyone writing code to use
extensions could presumably make that fix as well for the beta releases. Clearly, we are fixing this for final
release.
I appreciate this
bug, though, since it is a great example of the need to be meticulous with
checking text. That file is not that
large, but reading XML can be tedious and typos can creep in. It is also an example of NOT changing strings
right before you release a piece of software.
Anyway, I thought I
would share this bug and fix. Extensions
are pretty terrific - check them out if you have a preview account at https://prerelease.tableau.com/
Questions, comments,
concerns and criticisms always welcome,
