Event listener with a Workflow Launcher

Hello,

I have workflow launcher active on a directory.

Also have a custom event listener set on the same directory. The event listener moves files to a different folder.

Problem is the workflow is interfering with the event listener as the event listener can't move the files since it's in a workflow.

How to work around this?

What is your requirement, that you want to move things around while potentially at the same time a workflow is started for it?

Kind regards,

Jörg

We wanted to create a tools page to delete a node eg ecom data node , where we will have a button to request deletion and once it is approved by workflow process the node is deleted and replicated to publish server .

Hi,

I think I understand your usecase, but at which point comes this EventHandler into the play?

Are you referring Java logic that implements javax.jcr.observation.EventListener?

This is the error I'm receiving, I'm guessing my event listener is moving the file before DAM XMP Writeback is finished? com.day.cq.workflow.WorkflowException: execute: cannot set last modified, asset [{/content/dam/rogers/rpl_brandpublications/prism/CHE_20160701_1785745288_prism.xml/jcr:content/metadata}] in payload doesn't exist for workflow [{VolatileWorkItem_node1_etc_workflow_instances_server0_2016-08-03_1_dam-xmp-writeback_660}]. at com.day.cq.dam.core.process.AssetSetLastModifiedProcess.execute(AssetSetLastModifiedProcess.java:202) at com.day.cq.workflow.compatibility.CQWorkflowProcessRunner.execute(CQWorkflowProcessRunner.java:93) at com.adobe.granite.workflow.core.job.HandlerBase.executeProcess(HandlerBase.java:189) at com.adobe.granite.workflow.core.job.JobHandler.process(JobHandler.java:244) at org.apache.sling.event.impl.jobs.JobConsumerManager$JobConsumerWrapper.process(JobConsumerManager.java:500) at org.apache.sling.event.impl.jobs.queues.JobQueueImpl.startJob(JobQueueImpl.java:291) at org.apache.sling.event.impl.jobs.queues.JobQueueImpl.access$100(JobQueueImpl.java:58) at org.apache.sling.event.impl.jobs.queues.JobQueueImpl$1.run(JobQueueImpl.java:227) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745)
