[rt-users] Mason Cannot resolve file to component

[Behzad Mahini]

Just in case others will run into this issue, I have a workaround  
solution.......After digging I realized this was an issue in how Mason  
is being called by RT (i.e., RT's source code  "webmux.pl", as for  
some odd reason Mason's Handler for my Prod. server is not getting  
set  -- related line in webmux.pl is => $Handler =  
RT::Interface::Web::Handler->new(RT->Config->Get('MasonParameters'));



The (temporary) workaround to address this issue for me, was to add  
the following lines to my RT_SiteConfig.pm:

Set($MasonComponentRoot, "/path_2_your_RT/share/html");
Set($MasonLocalComponentRoot, "/path_2_your_RT/local");
Set($MasonDataDir, "/path_2_your_RT/var/mason_data");
Set($MasonSessionDir, "/path_2_your_RT/var/session_data");


I believe this is a potential bug, as my RT_Config.pm &  
RT_SIteConfig.pm for the 2 servers (prior to inclusion of the above 4  
lines in my Prod. server) were exactly similar .
