Unfortunately I do have a custom host variable “Location” with a capital letter at the beginning.  
This wasn’t a big deal until now.  
When using the Cube Module it is showing the variable with the capital “L” in the drop-down list but when selecting it it is converted to a small “L”.

URL:  
`.../icingaweb2/cube/hosts?dimensions=Location&showSettings=1#!/icingaweb2/cube/hosts/details?dimensions=location&location=ber`

When selecting _“Show host status”_ everything is fine (hosts are displayed) but the director function is showing _“Modify 0 hosts”_ and throwing this error when clicked:

```auto
Uncaught Error: Call to a member function hasConnection() on bool in /usr/share/icingaweb2/modules/director/library/Director/Web/Form/DirectorObjectForm.php:145
Stack trace:
#0 /usr/share/icingaweb2/modules/director/application/forms/IcingaMultiEditForm.php(28): Icinga\Module\Director\Web\Form\DirectorObjectForm->object()

#5 /usr/share/php/Icinga/Web/Controller/Dispatcher.php(7

```

One of my approaches would be modifying the variable to small letters directly in the Icinga Director database (2000+ hosts).  
Is this a good idea?  
Any other recommendations? Opening an Issue for the Cube Module?

I’ve seen that there is a new Cube Module release planned for next week (v1.2.0) but I haven’t found any open/closed issues that correspond to this error.

Thanks for your comments!

Hi,

there is already an issue for this: [Dimension slicing by custom data field names with certain characteristics cause failures or stacktrackes · Issue #62 · Icinga/icingaweb2-module-cube · GitHub](https://github.com/Icinga/icingaweb2-module-cube/issues/62)

And it’s fixed in the master, the next release will include it.

Thanks for the quick reply! I’m sorry for missing that issue (or didn’t I get it?).  
It saved my day. I’m looking forward to the next release.
