Hi Mathias, I responded to this email on Wednesday, but I'm not sure if it went through because I'm not seeing it when looking in ponymail, so I am resending.
Hope this helps. -Bryan ---------- Forwarded message ---------- From: Bryan Bende <[email protected]> Date: Wed, Sep 28, 2016 at 10:21 AM Subject: Re: Questions about Custom Processor Design To: [email protected] Hi Mathias, Glad you are enjoying building processors! You raised some great questions, and some of these ideas have definitely come up before. For changing the allowable values based another property, currently you can't do this, but there is a JIRA for this improvement [1]. The current approach is to use a custom validate method to ensure that properties that depend on each other are set appropriately. For building your own property editor, I'll have to defer to others, but I believe you might be able to accomplish this by building a custom UI for your processor. There are a couple of processors that have custom UIs, I believe the JOLT transform processor is one example. For the default schedule, you currently can't do this, but this JIRA captures that idea [2]. Hope that helps. -Bryan [1] https://issues.apache.org/jira/browse/NIFI-1121 [2] https://issues.apache.org/jira/browse/NIFI-1526 On Wed, Sep 28, 2016 at 10:11 AM, Mathias Tiberghien < [email protected]> wrote: > Hi, > > I’m working on Nifi Custom Processors and I really enjoy it! > > I have a couple of questions: > > - Is it possible to change the the allowed values based on a > property change?
