Did you register your app class to JFactory::$application? If not, you're
probably hitting the error because something is calling
JFactory::getApplication() and trying to boot a web app.

Steps to reproduce the issue

JTableCategory used in JApplicationCli like in ExampleApp in code below.
Expected result

Categories should be added.
Actual result

Error occurs when trying to store the second category:
Application Instantiation Error caused by line 890 in
libraries/joomla/table/nested.php:
$this->_observers->update('onAfterStore', array(&$result));
(If I remove the line 890, the insertion works.)
System information (as much as possible)

PHP 5.4.36-0+deb7u3
Joomla! 3.4.1

No, there ist no application registered - is this required with JApplicationCli scripts?

Seems to help - thanks. Didn't find this in API description or examples.

For safe bets it's a requirement. Most of the other JFactory objects can
build fine regardless of app, but for CLI you're better off setting it.
And ya that's documentation we need.

Okay, I'll publish the working version as an example on github. Thanks for the fast reply. Is there a documentation site, where I can contribute?

Working version here:
https://github.com/stoffels-it/joomla-extensions-examples/blob/master/insert-cat-example.php

I hit this same problem -- what do I need to add in order to register the app class ?

woops, please ignore my last question ... just spotted your 'working version' and that has all I need ... many thanks!

Hi There,

I was trying to use the code from the above working version to simply instantiate a JApplicationCli object, but it seems that my code just dies when the parent constructor is called. T1 is printed out on the terminal, but T2 is not. What am I doing wrong? Thanks!

@wanderlusted18 can you please open a new Issue as comments on closed Issues didn't get much Notice, thanks.

I created a new issue here:

Thx!
