I want to be able to set the 'Elasticsearch URL' property dynamically from an atttribute. Assume I have an attribute set as follows, es_host = http://<my_es_server>. Then if I set {quote} 'Elasticsearch URL' = \${es_host} {quote} then what I get is !screenshot-1.png! I also tried it with es_host = <my_es_server> and 'Elasticsearch URL' = http://${es_host} and what I get is !screenshot-2.png! was (Author: joewarner): The behaviour I'm seeing now isn't what I remember, so my original description may not be accurate, but I think the following should illustrate the problem.

The Index property > works correctly however. The property validates whether the value looks like > a URL. But it seems like this validation is taking place before the > expression is evaluated. Also, expressions like 'http://${url}' still are not > evaluated. > Technically I guess this isn't a 'major' issue, but it is quite painful to > use it without the replacement happening. See also NIFI-4396 which is very > similar behaviour. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
