By default for each WebScript in Alfresco there is a unique transaction.
You can try to change the transaction element in the webscript descriptor using the requiresnew value:


<transaction>requiresnew</transaction>
‍‍‍

Maybe you could solve in this way.

But if you need to implement a more complex procedure you have to implement your own WebScript using a Java-Backed WebScript and using RetryingTransactionHelper.

Java-Backed WebScript:

Transactions:

Hope this helps.

My problem proves that is not true, one webscript change data in other webscript ?

I try <transaction>requiresnew</transaction> and this config change absolutly nothing. :x

Can exist a solution for webscript with javascript controler ? or only in java ?

I think that you have to use the Java language, Alfresco doesn't provide any way to manage transactions using the Javascript API.
