My aim is to count the number of views on documents. So I have designed the aspect viewable and has property views to store the number of views and written the following class implementation.
public void init() {
this.onContentRead=new JavaBehaviour(this, "onContentRead", notificationFrequency.TRANSACTION_COMMIT);
this.policyComponent.bindClassBehaviour(QName.createQName(NamespaceService.ALFRESCO_URI, "onContentRead"), QName.createQName(SomeCoRatingsModel.NAMESPACE_SOMECO_RATINGS_CONTENT_MODEL, SomeCoRatingsModel.ASPECT_SCR_VIEWABLE), this.onContentRead);
}
public void onContentRead(NodeRef nodeRef){
int views=0;
views=(Integer)nodeService.getProperty(nodeRef, QName.createQName(SomeCoRatingsModel.NAMESPACE_SOMECO_RATINGS_CONTENT_MODEL, SomeCoRatingsModel.PROP_VIEWS));
views+=1;
nodeService.setProperty(nodeRef, QName.createQName(SomeCoRatingsModel.NAMESPACE_SOMECO_RATINGS_CONTENT_MODEL, SomeCoRatingsModel.PROP_VIEWS), views);
}
when I view the document from share than it triggers the error.

Solved! Go to Solution.
I believe the following blog post can give you some ideas.
Alfresco – Implementing delete behavior | Programming and So
In that case, the processing is executed "after commit".
You are trying to write data in a read-only transaction - of course this will fail. In this use case, you will have to create a custom / nested read-write transaction using the retrying transaction handler (if the enclosing transaction is read-only). Only within the new transaction (or after you have verified the current transaction is read-write) are you safe to call setProperty
Thanks Axel,
Any Documentation or implementation to refer would be more helpful.
