Solved: Re: onContentRead policy failed to execute.

rohit9637 · ‎3 Jan 2018

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.
