I am attempting to migrate an existing application with Apache Trinidad running on Tomcat 7 to Tomcat 8 and receiving the error below due to the usage of .
From what I can tell, Trinidad is on life support. The site is riddled with dead links and there has not been an update for 1/2 a year.
The original purpose of the Trinidad convertNumber component was to be more strict and throw a validation error if an invalid number was input i.e. 123.23.455.
Questions: 1. Is Trinidad EOL or are there plans to update Trinidad to be compatible with the Tomcat 8 specs? 2. Does MyFaces impl of convertNumber provide the same validation as Trinidad's convertNumber component?
Convert Number Component:
<tr:convertNumber maxFractionDigits="4" />
Exception:
