Hi Folks,
is there a quick way to read in camunda user of a spacial group and use them inside a HTML Form in an User Task.
Example: Read in all Department Heads to let an assignee of a task choose one of them for a approval. This one should be the assignee of next tast.
Thanks in advance,
Sebastian
Hi @SebLei77,
Below post might be of help to you
This works for me, but unfortunelly the value of the cmbApprove variable contains
string:userid …
Do you know what to do? Thank you!
Hi @SebLei77,
It works properly if track by is used as in below
<select required
cam-variable-name="cmbApprover"
cam-variable-type="String"
ng-model="selectedUser"
ng-options="user as (user.firstName + ' ' + user.lastName) for user in users track by user.id">
</select>
or if ng-repeat is used
<select required
cam-variable-name="cmbApprover"
cam-variable-type="String"
ng-model="selectedUser">
<option ng-repeat="user in users" value="{{user.id}}">{{ user.firstName + ' ' + user.lastName }}</option>
</select>
Personally I don’t use cam-variable-* directives. Instead I use pure ng-model directive only and do variable manipulations utilizing javascript camForm.variableManager object as in below post
Dear all,
thank you for the information.
I added the following code snippet to my html form:
<div class="form-group">
<label for="userSelection" class="col-sm-2 control-label">User Selection</label>
<div class="col-sm-10">
<select required
cam-variable-name="cmbApprover"
cam-variable-type="String"
ng-model="selectedUser"
ng-options="user.id as (user.firstName + ' ' + user.lastName) for user in users">
</select>
<script cam-script type="text/form-script">
inject(['$scope', 'camAPI', function($scope, camAPI) {
var groupName = 'all-users';
var User = camAPI.resource('user');
User.list({memberOfGroup: groupName}, function(err, data) {
if (!err) {
alert('Data: ' + JSON.stringify(data));
$scope.users = data;
}
});
}]);
</script>
</div>
</div>
the user selction drop down remains empty. is there any error in my code?
Best Regards
MaxHi @MSc_Conet,
Have you tried the code in a clean html form?
Could you please share your html from…
Hi @hassang
my html form code is:
<form name="approvalForm1" class="form-horizontal" role="form">
<!-- read-only field -->
<div class="form-group">
<label for="name" class="col-sm-2 control-label">Item to be approved</label>
<div class="col-sm-10">
<input type="text"
name="description"
cam-variable-name="description"
readonly="true"
class="form-control" />
</div>
</div>
<!-- attachment -->
<div class="form-group">
<label for="attachments" class="col-sm-2 control-label">Attachments</label>
<div class="col-sm-10">
<div class="file">
<label>
<input type="file"
name="attachments"
cam-variable-name="attachments"
cam-variable-type="File"
cam-max-filesize="10000000"
class="form-control" />
</label>
</div>
</div>
</div>
<!-- checkbox -->
<div class="form-group">
<label for="approved" class="col-sm-2 control-label">Genehmigen?</label>
<div class="col-sm-10">
<div class="checkbox">
<label>
<input type="checkbox"
name="approved"
cam-variable-name="approved"
cam-variable-type="Boolean"
checked="checked"
class="form-control" />
</label>
</div>
</div>
</div>
<div class="form-group">
<label for="userSelection" class="col-sm-2 control-label">User Selection</label>
<div class="col-sm-10">
<select required
cam-variable-name="cmbApprover"
cam-variable-type="String"
ng-model="selectedUser"
ng-options="user.id as (user.firstName + ' ' + user.lastName) for user in users">
</select>
<script cam-script type="text/form-script">
inject(['$scope', 'camAPI', function($scope, camAPI) {
var groupName = 'Accounting';
var User = camAPI.resource('user');
User.list({memberOfGroup: groupName}, function(err, data) {
if (!err) {
alert('Data: ' + JSON.stringify(data));
$scope.users = data;
}
});
}]);
</script>
</div>
</div>
</form>
the user selection drop down after deployment is empty
Hi @MSc_Conet,
Try below GET REST call
/user?memberOfGroup=Accounting
https://docs.camunda.org/manual/7.15/reference/rest/user/get-query/
Does it return result?
thanks.
it returns an emtpy array. only “/user” returns all users or “/group” returns all user groups. this would be sufficient for my use case I guess. but how would I integrate this into my html form script ( in ng-model or ng-options) to have a dropdown of user groups for example ?

Hi @MSc_Conet,
Then the code is working properly.
You need to change the filter of User.list so if your need is to get all users then replace the filter {memberOfGroup: groupName} with {}
thanks! I made it work like this - by creating an additional group allUsers which contains all users:
<div class="form-group">
<label for="userSelection" class="col-sm-2 control-label">additional Approver</label>
<div class="col-sm-10">
<select required
cam-variable-name="additionalApprover"
cam-variable-type="String"
ng-model="selectedUser"
ng-options="user.id as (user.firstName + ' ' + user.lastName) for user in users">
</select>
<script cam-script type="text/form-script">
inject(['$scope', 'camAPI', function($scope, camAPI) {
var groupName = 'allUsers';
var User = camAPI.resource('user');
User.list({memberOfGroup: groupName}, function(err, data) {
if (!err) {
alert('Data: ' + JSON.stringify(data));
$scope.users = data;
}
});
}]);
</script>
</div>
</div>
the question now is in the following user task I want to assign that user as assignee with ${additionalApprover} but it does not work as it returns a String and not the user itself. Do you know how to address the additional Approver correctly?
Hi @MSc_Conet,
This expression should work as long as it is evaluated to string value represents the user Id
Hi @hassang
the variable is shown like this
so in this example the user john is correctly taken over but it does not appear in his inbox as it is string:john. Do you know what to else to do with the variable “additionalApprover” to evaluate this as string…?

Hi @MSc_Conet,
Below post contains the answer to this
Hi @hassang
perfect! thank you so much 
Having a parallel gateway combines two approvals which I am checking afterwards in an expression as below:
The workflow item won’t go further although both variables are true. Do you see any mistake in the syntax?
