OptimisticLockException when updating an entity #8

Closed karianna closed 11 years ago

Hi there,

This is from using the samples (except I've changed the entity name from Sampel to Tag). After updating an existing Tag entity, I get the following exception (I'm using the in-memory datastore that comes with Play):

play.api.Application$$anon$1: Execution exception[[OptimisticLockException: Data has changed. updated [0] rows sql[update tag set name=? where id=?] bind[null]]] at play.api.Application$class.handleError(Application.scala:289) ~[play_2.10.jar:2.1.1] at play.api.DefaultApplication.handleError(Application.scala:383) [play_2.10.jar:2.1.1] at play.core.server.netty.PlayDefaultUpstreamHandler$$anon$2$$anonfun$handle$1.apply(PlayDefaultUpstreamHandler.scala:144) [play_2.10.jar:2.1.1] at play.core.server.netty.PlayDefaultUpstreamHandler$$anon$2$$anonfun$handle$1.apply(PlayDefaultUpstreamHandler.scala:140) [play_2.10.jar:2.1.1] at play.api.libs.concurrent.PlayPromise$$anonfun$extend1$1.apply(Promise.scala:113) [play_2.10.jar:2.1.1] at play.api.libs.concurrent.PlayPromise$$anonfun$extend1$1.apply(Promise.scala:113) [play_2.10.jar:2.1.1] javax.persistence.OptimisticLockException: Data has changed. updated [0] rows sql[update tag set name=? where id=?] bind[null] at com.avaje.ebeaninternal.server.persist.dml.DmlHandler.checkRowCount(DmlHandler.java:103) ~[avaje-ebeanorm-server.jar:na] at com.avaje.ebeaninternal.server.persist.dml.UpdateHandler.execute(UpdateHandler.java:88) ~[avaje-ebeanorm-server.jar:na] at com.avaje.ebeaninternal.server.persist.dml.DmlBeanPersister.execute(DmlBeanPersister.java:86) ~[avaje-ebeanorm-server.jar:na] at com.avaje.ebeaninternal.server.persist.dml.DmlBeanPersister.update(DmlBeanPersister.java:66) ~[avaje-ebeanorm-server.jar:na] at com.avaje.ebeaninternal.server.persist.DefaultPersistExecute.executeUpdateBean(DefaultPersistExecute.java:91) ~[avaje-ebeanorm-server.jar:na] at com.avaje.ebeaninternal.server.core.PersistRequestBean.executeNow(PersistRequestBean.java:485) ~[avaje-ebeanorm-server.jar:na]

Hi again Martijn,

I thouhgt that I've fixed this one on 0.5.0-SNAPSHOT. On which step do you exactly get this one? I don't see any play2-crud calls on your stacktrace.

Hi Hakan,

I'm still on 0.4.0 SNAPSHOT, let me upgrade and try again.

Cheers, Martijn

After updating to 0.5.0 this was resolved.
