4. Its no possible in 1.10 to have two different Dialog+ Fields with the same value. This was possible in 1.9 versions though.

To reproduce create 2 custom dialog+ fields. For example use "SSH User Groups" und "SSH Server Groups".
In "Dialog-Admin" -> "Custom Dialog+" try to enter the same value (e.g. QA) into both. This results in the following error:

Error!
General error: Following values could not be saved because it would lead to duplicate entries: QA

5. Its possible to enter a numeric "0" into a dialog+ field via api but not via the administration ui.

Nearly a year after i opened this issue , we updated to version 1.10.1 and the api plugin to 1.9 to see if we could finally use dialog+ fields. However now we stumbled upon a multitude of new bugs concerning dialog+ fields:

1. Undeletable Multivalue in GUI

Description:
Multiple Dialog+ selections will not be deleted in IDOIT gui.
How to reproduce:

• We have the following Objecttype hierarchy in Quick configuration Wizard "Infrastruktur->Server".
• Added User Defined Category "Users"
• Under Users we have a Dialog+ field called SSH Groups (where we have Values like "QA", "Staging" etc.)
• Choose multiple SSH Groups->Save
• Try to delete all those SSH Groups->Save
• Values are not deleted

2. Output Bug Dialog+ via API

Description:
When calling cmdb.category.read on a custom category with dialog+ fields, the output of the json object is utterly bugged.

How to reproduce:

• We have the following Objecttype hierarchy in Quick configuration Wizard "Infrastruktur->Server".
• Added User Defined Category "Users"
• Under Users we have a Dialog+ field called SSH Groups (where we have Values like "QA", "Staging" etc.)
• Call cmdb.category.read on it.
• Receive the following strange output:

shortened response:

{
                "f_text_c_1455200871361": "agage",
                "f_text_c_1455200573923": "test1",
                "objID": "1378",
                "f_text_c_1455200588403": "fsfs",
                "id": "4257",
                "f_text_c_1455200581454": "teshome",
                "f_text_c_1455200835586": "ffa",
                "f_popup_c_1480427993531": {
                                  "identifier": "SSH_Groups"
                }
},
{
                "f_text_c_1455200871361": null,
                "f_text_c_1455200573923": null,
                "objID": "1378",
                "f_text_c_1455200588403": null,
                "id": "4257",
                "f_text_c_1455200581454": null,
                "f_text_c_1455200835586": null,
                "f_popup_c_1480427993531": {
                                  "identifier": "SSH_Groups",
                                  "const": null,
                                  "id": "12",
                                  "title": "EDI",
                                  "title_lang": "EDI"
                }
}

• As you can see the output contains two "datasets" and one has only empty fields except correct dialog+ info. The other has all fields filled correctly but no dialog+ info. This surely is not how its supposed to be…

3. When configuring Events to execute a Script. The "from" field in the changes section is wrong.

• Configure Events to execute an external script when saving datasets.
• in the script decode base64 and parse the json data
• look at changes->from field its always undef.

Hi Guys,

im trying to realize a ssh public key distribution system based on idoit. I do have some troubles concerning dialog plus fields though:

1. I created a custom dialog+ called "sshgroups" and filled it with values like DEV, TEST, QA and the likes
2. Created a custom category called "ssh" and put above "sshgroups" as a field inside
3. Used the Quick configuration wizard to put the custom category under Kontakte->Personen->ssh
4. Went into Kontakte->Personen and assigned some values in the sshgroups dialog plus to a random person e.g. "max mustermann" has values QA and DEV and TEST

Now when i call cmdb.objects.read with params filter => {type => 53} i am able to loop through all the persons and get the objid of "max mustermann".
So when i now call cmdb.category.read with params  objID => {id of max mustermann}, category => "C__CATG__CUSTOM_FIELD
S_SSH"

i get the following datastructure for the dialog+ field:

          'f_popup_c_1480604992331' => {
                                         'identifier' => 'SSH_Groups',
                                         'title_lang' => 'QA',
                                         'const' => undef,
                                         'title' => 'QA',
                                         'id' => '21'
                                       },

In this structure only the first entry of the persons ssh group (QA) is shown. However i selected multiple groups QA and DEV and TEST.
Is there something i am missing about dialog plus fields? i can read all other kinds of fields with the method shown above, but with dialog+ i never get all the selected values in my data structure.

EDIT: Forgot to mention. Im using JSON::RPC::Legacy::Client; with perl to query the api.

Thanks everybody for helping me out!
