Performance measure exception

Hi,

At the end of replication run using the experimenter, the following exception message appears : "exception: FlexScript exception: Property "last" accessed on invalid node. at MAIN:/project/exec/replications/PerformanceMeasures"

I receive 1 exception per replication.

This is a really simple model to show the issue : issue-experimenter-and-dashboard.fsm

Does anybody have the same problem ?

Thanks for your help

Laetitia

This is a bug with the Chart Templates. It has been fixed, and should be resolved in version 18.0.3. For now, you will need to "Install" both of the templates. To do so, double-click on each chart, go to the Advanced tab, and click the "Install" button.

As a little background, a Chart Template is an object that is composed of many other tools, like Groups, Statistics Collectors, Process Flows, and Calculated Tables, along with a chart. The template configures all of these objects to work together to create a chart, and provides a simple interface. When you install a template, each tool is put in the Toolbox. This removes the nice interface, but allows you to change or update how the chart collects or reports data. In your case, it will also fix this bug.
