Hello,

I need your help to find a bug in my action

In the action, I want to create one directory, check it exists, if not, I created. To do that :

NodeRef nodeOnDisk = nodeService.getChildByName(parentDirectoy,
               ContentModel.ASSOC_CONTAINS, nameDirectory);
if (nodeOnDisk != null) {
   …
} else {
   FileInfo fileInfo = fileFolderService.create(parentDirectoy,
                  nameDirectory, ContentModel.TYPE_FOLDER);
‍‍‍‍‍‍‍‍‍

All work good if I start action with one file. But if I try to use this action in parallel (send two 2 files to start, which will created the same directory). The nodeService say (for the 2 actions) that the directory (nameDirectory) doesn't exist, but after the fileFolderService generate a error because the directory exist. When a action is running, all of the other wait (I use the synchronisation with lock) :
Start 2 action (action_A and actionB) :

(This is a temporal schema)
action_A  ……………………………………. action_B   
begin (get the nodeService)…………………..begin (get the nodeService)
create directory……………………………….wait
finished, signal other action to start    
………………………………………………..awake
………………………………………………..create directory (and error appears)

I think that the nodeService have old information about the store. Has someone an idea to have actual information about nodeService (or another way to do this) ? :?:


More info : The creation directory si done with this kind of transaction :

boolean resultCreateDirectory = transactionService
                     .getRetryingTransactionHelper()
                     .doInTransaction(
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;new RetryingTransactionHelper.RetryingTransactionCallback<Boolean>() {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;public Boolean execute()
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;throws Throwable {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CREATE OF DIRECTORY
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;});
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}

How do you trigger those actions ?
