B4J Question [ABMaterial]Two Charts in one Row Issue

[rwblinn]

Hi,

developing an ABMaterial 2.20 application with 2 gauges and charts in one row with data provided from an ESP8266 via MQTT.
Going step-by-step:
1) Started with one chart in a row = working fine.

2) Added a second chart which is updated, but the first chart is not. Why?

Each of the charts have an unique ID and are using dedicated lists for values and labels.
The logs also show correct data being fed from an ESP8266 via MQTT.
The source is attached - look at ESPDashboardPage.bas.

Any hints what could be the cause?
