drccrd opened a new issue, #6781:
URL: https://github.com/apache/incubator-kie-drools/issues/6781
**Summary:** Under `ExecutableModelProject`, a `global` declared in one
DRL/package and referenced in a pattern constraint in another DRL/package of
the same KieBase fails to compile, although the classic compiler resolves it.
Globals in Drools are KieBase-wide, but the exec model only collected globals
from the rule's own package and packages imported with a wildcard.
**Reproducer** (`Person` = any POJO with a `BigDecimal getMoney()`):
```drl
// globals.drl
package org.test.globals;
global java.math.BigDecimal threshold;
// rules.drl
package org.test.rules;
import org.test.Person;
rule R when
Person( money.compareTo(threshold) < 0 )
then end
```
- **Expected:** compiles (as in classic mode).
- **Actual:** build error — *"Unable to Analyse Expression
money.compareTo(threshold)"* (`threshold` not in scope).
**Root cause:** `RuleContext.addGlobalDeclarations()` collected globals only
from the current package plus packages imported via wildcard (`import x.*`).
**Suggested fix:** collect globals from every package registry in the
KieBase:
```java
typeDeclarationContext.getPackageRegistry().values().stream()
.filter(Objects::nonNull)
.filter(reg -> reg.getPackage() != null)
.forEach(reg -> globals.putAll(reg.getPackage().getGlobals()));
```
