Guided Decision Tree - update/insert value based on lookup table

[Radovan Tomala]

Hello,

I am currently working on a PoC for our client to find out the capabilities of Business Central.

I have a table of Job names and their ids and recieve a Job name as an input. I need to create a new variable with id of given job which I have to find in the lookup table. I need to work with this value in the nexts steps of the tree.  Would this be possible using Guided decision tree? I tried using guided decision table for the lookup but I did not find a way to insert it into the tree.

Thank you.

Sadly the Guided Decision Tree capabilities within Business Central are quite limited and do not support your need.

With a Guided Decision Table you could probably use a "global variable" to provide a lookup service; calling this from the RHS (THEN) of a rule to retrieve ID from Name.

The User Guide provides details of rules' RHS and use of "global variables".

Well, i dont know where to start.

I am using Amazon Corretto 8 and everything its fine.

When i build a docker image with Amazon Corretto with Amazon Linux 2 jdk 8. The error its absolute not clear what i am doing wrong or whats is going on.

The command:

kieServices.newKieBuilder(kfs).buildAll();

Code:

private static synchronized KieResources getFactoryService() {
    return LazyHolder.service;
}

private static class LazyHolder {
    private static final KieResources service = ServiceRegistry.getService(KieResources.class);
}

File: org.kie.internal.io.ResourceFactory

OBS: The LazyHolder.service its always null and get a npe.

Stack:

java.lang.NullPointerException: null

I found the issue. The “shade” process are missing some files.

Anyone has a codesample of Maven Shade that works on latest version of drools?
