AEM: Replicate to a specific publisher

2018-04-03

I've added the possibility to replicate to a single publisher under the already existing /etc/replication/treeactivation.html. The user can select an agent or keep the default (replicate to all publishers).

There is not that much code to show, I'll just summarize the most important parts.

Map<String, Agent> agents = agentMgr.getAgents();
List<String> agentIdsList = new ArrayList<>();
for(Map.Entry<String, Agent> entry: agents.entrySet()){
	Agent agent = entry.getValue();
	if(agent.isEnabled()){
		agentIdsList.add(entry.getValue().getId());
	}
}
...

<% for (int i=0; i< agentIdsList.size(); i++) { %>
	var option = document.createElement("option");
	var id = "<%= xssAPI.encodeForJSString(agentIdsList.get(i)) %>";
	option.text = id;
	option.value = id;
	select.add(option);
<% } %>
