## Description

### Steps to reproduce

1.   Set up two custom fields: 1x integer (e.g. Plan-ID) / 1x Float (e.g. Betrag)
2.  Add them to a work package type and enable them in a project
3.  navigate to that project and create at least two new work packages from that type. Make sure to add values to the custom fields you just created (Plan-ID and Betrag).
4.  Filter you work package table so that just these new work packages are displayed
5.  Configure the view as following:

<!-- end list -->

  - Group by = integer custom field (e.g. Plan-ID)
  - Display settings = display sums

### What is the buggy behavior?

*Please describe the bug in as much detail as possible. Example:*

  - The work package table wont load anymore. You will receive an "internal error" error code

### What is the expected behavior?

*Describe how the application should behave like. Example:*

1.  It is possible to group you list based on an integer custom field and display sums at the same time

### Screenshots and other files

WITHOUT grouping by Plan-ID (=integer) - everything as expected

Configuration that leads to the error:
