use of org.drools.compiler.integrationtests.facts.AFact in project drools by kiegroup.

the class UpdateTest method testNotIterativeModifyBug.

@Test

    // JBRULES-2809
    // This bug occurs when a tuple is modified, the remove/add puts it onto the memory end
    // However before this was done it would attempt to find the next tuple, starting from itself
    // This meant it would just re-add itself as the blocker, but then be moved to end of the memory
    // If this tuple was then removed or changed, the blocked was unable to check previous tuples.
