Mail template testing feature

JMIX version 1.5.4
Email Template Add-On

Problem experienced:
When passing parameter values from the template using the test feature the parameters are not passed and the actual variable is shown i.e. ${subject}.

When passing it programmatically into the parameter it works.

Hi,

Could you please provide detailed steps to reproduce the issue? Demo project that reproduces the issue is highly appreciated.

Regards,
Gleb
