[Wurst] Frentity: "Trying to assign entity to unit that already has an entity"

[4eNNightmare]

What is wrong with this code?

BattleSystem.wurst

package BattleSystem

import Entity

public abstract class BattleUnit extends UnitEntity

  construct(player p, int unitId, vec2 pos, angle facing)
    super(createUnit(p, unitId, pos, facing))

Summoner.wurst

package Summoner

import BattleSystem

public class Summoner extends BattleUnit

  construct(player p, vec2 pos, angle facing)
    super(p, SUMMONER_ID, pos, facing)

But when I call new Summoner() more than once it causes an error.
"Trying to assign entity to unit that already has an entity"
But I do not understand, because every time createUnit(p, unitId, pos, facing) was called it should be a new instance.

You code sample is too incomplete to judge. Frentity uses the UnitIndexer to attach entities to units, and the check for the error is a simple unit.getEntity() != null.
Thus apparently that unit-index already has an entity. Are you doing other illegal operations? Do you make use of custom unit UserData? Do you remove the unit without terminating the entity?
It can be caused by something else you did, leaving undestroyed entities. You could add some debug to see how many Battleunits/Entites get created, and how many destroyed to find leaks.

The error should normally print you a stacktrace, perhaps post that one as well to find the order of execution.

Also, does the error just occur now and it worked before, or did it never work? Are you dependencies up to date (using setup-> update project) ?
