Thank you for your cooperation.

If for any reason one of the hdb++es-srv device server is off the diagnostics can not be done. Is it the expected behavior?

Java exception occurs when removing archived attribute.

How to reproduce?

• in hdb-configurator-3.5
• add an attribute to the subscriber
• on the right-panel, in Started Attributes, right-click and select Remove Attribute
• the action never finishes because a Java Exception occurs

Hello, i'm in the process of installation of hdbpp suite and while the system works (i can configure and visualize my reccords) I encountered a bug/unusual behaviour as after few seconds the list of attributes to archive the program prints the message No heartbeat from dserver/hdb++es-srv/arch.

Expected Behavior

On start-up the program should list all attributes that were added to a subscriber device server.

Current Behavior

On start-up the program list all attributes during few seconds then prints the message No heartbeat from dserver/hdb++es-srv/arch and the program become unusable because if we try to delete this message as we would do with an attribute a division by 0 error occurs.

Possible Solution

During the few seconds affter the start up I was able to configure and launch the archiving of few attributes from the Tango Test device server and I was able to visualize those records in the Viewer tool. After reading this forum thread it seems that even if a lost of heartbeat from a device server occurs the events continue to be triggered so one possibility might be the simple suppression of the warning or better a popup that alert us of lost of heartbeat instead of blocking the entire program.

Hello.

I've downloaded the source code from this repo, compiled it with maven and tried to launch hdbpp-configurator, but it hasn't found its' main class

./start_gui.sh -configure
CLASSPATH=/usr/local/share/java/JTango.jar:/usr/local/share/java/ATKCore.jar:/usr/local/share/java/ATKWidget.jar:/home/tango/wk/hdbpp-configurator/target/hdbpp-configurator.jar:/usr/local/share/java/Jive.jar
Error: Could not find or load main class org.tango.hdb_configurator.configurator.HdbConfigurator

I edited start-gui to match my system configuration (Debian 9.7), here it is:

When I tried to execute .jar without any dependencies, I've got message:

Also I downloaded compiled .jars from bintray and got the same errors.

What am i doing wrong and can you help me to solve this problem?
