Microsoft.Activities.Expressions.IsTrue is gone after upgrade to newest version of UiPath

activities

#1

Hello, I just upgraded UiPath to the newest version and my workflow is no longer working because of an IsTrue activity which cannot be loaded. I have installed all available packages, but it is still not there. The error I get in the workflow is this:

Activity could not be loaded because of errors in the XAML.

And in the output I see the following error message:

Could not find type ‘IsFalse’ in namespace ‘http://schemas.microsoft.com/workflow/2012/07/xaml/activities’.

How can I resolve this? Has this activity been removed or is there a package that I for some reason do not have access to?


#2

Hello.

The activity Is true is included like you mentioned in Microsoft.Activities.Extended. Can you try to reinstall the the package?

Regards,
Cosmin

Hi, I tried uninstalling and reinstalling the Microsoft.Activities.Extensions now, but it did not work. I no longer have access to the Microsoft.Activities**.Expressions**, only the .Extensions. I cannot find a package called Microsoft.Activities.Expressions. I also no longer have the Microsoft.Activities
.Design
.Beta2
.Messaging

I.e. I am left with only .Extensions.

Hi tea, did you found a solution for this already? I had the same issue but after I installed package “Workflow Manager activites” all the ones you listed became available.


#5

Hi, it actually began working again by itself just as suddenly as it had stopped working, but today the error is back again. I had not done anything in my workflow since last time I published it, and when I opened it, the error message was there again. I will try uninstalling and reinstalling that package you mentioned.
Edit: Yes, that package solved it, thank you matsi!

Go to Manage Packages, Install Workflow manager activities. This will resolve the problem. you can find all the activities Microsoft->Activities->Expressions


#7

Hi, I am seeing this issue, I cannot see Microsoft->Activities->Expressions.
I have tried re-installing the packages to no avail.
Please can you advise?

Thanks
