Solving Property "value" accessed on invalid node and Activity is not shown

Hello everyone,

FlexSim gave me this exception:

FlexScript exception: Property "value" accessed on invalid node. at VIEW:/active/MainPanel/BackPanel/SplitterXPane/ToolTabPane~2/TabControl/QuickProperties/ToolPanel/ActivityProperties/Activity Properties/ActivityPropsTemplate~5>eventfunctions/showPanel

I tried to restart the Default Workspace, but it did not work for me.

One of the consequences of this exception is that I couldn't edit an activity (not in its icon or in Quick Properties).

When I close the Quick Properties the exception stopped appering, however I could not edit the properties of the bugged activity.

The solution I found is to split the set of activities (A,B,C,D,E) into (A,B,C) -> (D,E) (assuming D is the wrong activity). That worked for me.

Software Version:

FlexSim 23.1.2

Okay, sometimes works sometimes not. Sometimes when I create an activity I cannot delete it.

The bugged activities are all Run Subflows.

We'd need to see your model to understand what's happening.

I cannot send it. But don't worry, I will do it again...

A video would also help us to understand what you're experiencing. You can toggle the post to private if that helps.

I don't know why, I cannot accept any answer.

Recommendation: Increment save the model. I restart from the last saved model.
