[rules-users] reuse existing functions/imports when adding new rule at runtime
how to add a rule at runtime to an existing package without having to
re-add the functions and imports?
at the moment I do it like this:
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl(imports);
builder.addPackageFromDrl(functions);
builder.addPackageFromDrl(newrule, dsl);
// Check the builder for errors
...
ruleBase.addPackage(builder.getPackage());
that works fine but I don't like to re-add all the functions and imports
every time a new rule is added. it should be possible to define new rules
using the existing functions. is there a better way to do this?
I also tried to reuse the PackageBuilder and just add the new rule with
builder.addPackageFromDrl(newrule, dsl);
but this ends up in a NullPointerException:
java.lang.NullPointerException
at org.drools.reteoo.ReteooBuilder.removeRule(ReteooBuilder.java:224)
at org.drools.reteoo.ReteooRuleBase.removeRule(ReteooRuleBase.java:270)
...
best regards
