This behavior exists on 1.15.4, 1.15.5,1.15.6,1.16.RC2

It works fine with 1.11 releases which is what we have in the production

Without the patch, I don't think we can expect this in 1.16

So the last release it worked was on 1.11.3. I haven't tried in-between releases.

If someone suggests me where to look I can provide a patch.

PXE template that references host_param('param1') and host_param('param2')

Create host

• Hostgroup = Testing
• Parameters, override the one with empty value to contain some value param2 = SomeValue.
• Submit

Generated PXE template does not contain the value of param2. However, YAML in the web UI shows correct values.

For some reason my original description eat newlines so I am re-writing it again.

1. Create host
2. Select Hostgroup = Testing
3. Click on Parameters Tab
4. override the one with empty value to contain some value param2 = SomeValue.
5. Click Submit

Generated PXE template does not contain the value of param2. However, YAML in the web UI shows correct values.

Now, go through following steps (work around) to generate correct PXE file.

1. Cancel Build
2. Build

Generated PXE file contains correct values.

Last known version that works correctly is 1.11.3.
Last known versions that it does not work are 1.15.6 and 1.16.RC2
