Under Python 3.6, TreeEditor_demo.py raises the following exception:
TypeError: unhashable type: 'QTreeWidgetItem'
when attempting to create a new Department or Employee.
A possibly related posting, for Qt5, is: QTreeWidgetItem not hashable in python3
Is TreeEditor usable in Python 3? If so, could someone provide a solution.
Thanks.

Core: Exception handler (WEB): Uncaught TYPO3 Exception: Cannot use object of type __PHP_Incomplete_Class as array | Error thrown in file typo3/sysext/backend/Classes/Controller/Page/TreeController.php in line 189
This happened after a core update to TYPO3 - 9.5.17

The following thanks to Michael Hitzler.
As far as I can see there is already a solution within the install tool in class BackendUserConfigurationUpdate.
This seems to address exactly the issue.
Not quite sure in which version the additional migration task has been added, but it helps you solving the issue system wide.
Just got to module Admin Tools -> Update and select Update Wizard.
There you should see a new, not yet executed migragtion task:
Update backend user configuration array
The backend user "uc" array, which is persisted in the db, now only allows for arrays inside its structure instead of stdClass objects. Update the uc structure for all backend users.
Execute this migration task and your BE users will be updated and have a sane uc configuration in the end.
Problem solved and page tree can be loaeded again.
./typo3cms upgrade:wizard backendUsersConfiguration
Should solve the issue.
Trying to create a models for WTForms using Mongo Engine according to the documentation here and getting the error returned Instance of 'MongoEngine' has no 'StringField' member when trying to create a model as such
class Example(db.Document):
Value = db.StringField(max_length=200)
The workaround is to use mongoengine package directly, which is installed as a dependency of flask_mongoengine.
from mongoengine import StringField
class Example(db.Document):
value = StringField(max_length=200)
The error is provided by pylint - a code analysis tool for python, it just fails to validate dynamic members of db. Your code is correct it will won't fail at runtime.
Another option is to setup project .pylintrc to silence such warnings, or place pylint comments over the line displaying error:
# pylint: disable=no-member
value = db.StringField(max_length=200) # no error
I'm quite new to Modelica and I'm trying to understand some basic examples. I'm looking at the example IBPSA.Fluid.FixedResistances.Examples.PlugFlowPipe and checking this model gives me the following error
Number of classes to check: 2
Checking: model IBPSA.Fluid.FixedResistances.Examples.PlugFlowPipe... 0.2350000000001273 seconds -> FAILED!
Error String:

It seems that the module pip.cor.timDel uses the function spatialDistributuon. My guess is that there is something wrong with pip.cor.timDel.t_in_start or pip.cor.timDel.t_out_start? It would be greatly appreciated if someone could help me with this.
P.S. I'm using OMEdit v1.14.0 on windows 10 with Modelica library v3.2.3
OpenModelica does not support the function spatialDistribution yet, i opened a ticket on Trac where you can follow for the current development status.
I'm trying to create a webpage using TYPO3 8.7, but when i go to Localhost/index.php it says "Oops an error has occured".
The only way i can see my webpage, is through the TYPO3 backend login apperently.
This is the error that it logs in the backend of TYPO3:
>
Core: Exception handler (WEB): Uncaught TYPO3 Exception: Call to undefined >function TYPO3\CMS\IndexedSearch\mb_strcut() | Error thrown in file >/var/www/html/typo3_src-8.7.0/typo3/sysext/indexed_search/Classes/Indexer.php in >line 1314. Requested URL: Localhost/index.php
And my line 1314 is this:
$bodyDescription = mb_strcut($bodyDescription, 0, $maxL, 'utf-8');
I'm very new to this. So far i've been able to sort all bugs with the help from these forums and others, but unfortunately I can't find any solution to this one.
Any help is greatly appreciated.
Let me know if i need to provide some additionel information.
