Unable to Add Form Block on Printers

[SumErgoCogito]

I get the error message: "You cannot add several blocs with type 'Insertion in the form' on same object" when I try to create a new form block within the main form of the printer-type object. I do not have any existing custom fields for printers nor do I have any currently existing form blocks that include printer as an asset type. I get the same error when attempting to do this for any other asset types. I do have main form blocks for Computers, Tickets, Peripheral (Custom Devices), Phone and Contract.

edit: Updated to fields 1.3 and this problem still persists. I'm unable to add any new main form blocks, even for asset types that do not have any custom fields. Here is the message in my /var/log/httpd/error_log:

Found the reference to /ajax/container_itemtypes_dropdown.php in inc/container.class.php line 402. I commented the line out and tried again, but get the same message "You cannot add several blocks with type 'Insertion in the form' on same object". No more httpd error message however.

Same here.
GLPi: 0.90.5
fields: 0.90-1.3
File injection: 2.4.1

No additional debug errors.
Funny I found your 402 reference inc/container.class.php at 241
Commented out the whole if and message persists.

Hello,
Could you download the master sources and do a new test?
I believe that #57 is fixing these problems.
Thank you

I'm getting a 500 error now when I attempt to add a new form block. Here is the relevant message from /etc/httpd/log/error_log

[Fri Sep 23 09:26:53.534376 2016] [:error] [pid 2432] [client 10.36.27.152:52132] PHP Fatal error: Call to undefined function array_column() in /usr/share/glpi/plugins/fields/inc/container.class.php on line 240, referer: http://hostname/plugins/fields/front/container.form.php

To "update" to the master branch I first disabled the plugin, backed up the current plugins/fields directory, then overwrote the plugins/fields directory with the files from the master branch.

Sorry, just realized I am still on php 5.4. Let me update that and get back to you.

Works great! Thanks tomolimo.
