I understand not wanting to fix blindly unless the scenario is clear.
The DRL is this:
```java
package com.mycompany.myproject.engine.rules.model;
//generated from Decision Table
import com.mycompany.myproject.engine.rules.model.*;
global com.mycompany.myproject.engine.rules.model.ServerCodeRuntimeService
serverCode;
dialect "mvel"
// rule values at B13, header at B8
rule "Tank Rules-SmartBIN_13"
salience 65535
when
$asset:
Sbtanknew_1_0_6($asset.devices.tank_device.properties.tanklevel_status !=
"Nearing Empty", $asset.devices.tank_device.readings.tank_level <
$asset.properties.empty_fill_level_threshold)
then
$asset.getDevices().getTank_device().getProperties().setTanklevel_status("Nearing
Empty");
$asset.getDevices().getTank_device().getProperties().setTanklevel_color("Red");
$asset.getProperties().setTank_level_status("CRITICAL");
AlertMessage message = new AlertMessage("Nearing Empty");
message.withParam("value",
$asset.devices.tank_device.readings.tank_level);
message.withParam("alias", "sb_device_tank_level");
message.withParam("field", "Tank Level");
message.withParam("is_required", "Required");
insert(message);
end
```
if I drop `$asset.devices.tank_device.readings.tank_level <
$asset.properties.empty_fill_level_threshold`, the above error goes away and a
different one appears, but this one I need to investigate further. It also
seems related to the fact that a generic class is involved. (I understand
`$asset` inside the condition is redundant).
the model classes (eg:Sbtanknew_1_0_6) are derived from base classes and are
runtime generated with byte-buddy, overriding several generic parameters of the
parent class. I think this is where the issue comes from, and why it's not easy
to isolate. I will try.
