Non-informative stack trace

[jifeon]

When something goes wrong I get stake trace like this:

14:22:02.568 - error: Error process page /test-menu GET Error: Parameter "filePath" has bad value "undefined", not suitable for path generation
    at RouterBase._getParameterValue (/home/jifeon/projects/bnsf-adwiki/libs/bnsf/node_modules/router-base/lib/router-base.js:435:19)

    at apply (/home/jifeon/projects/bnsf-adwiki/desktop.bundles/index/index.bemtree.js:119:40)

Error message is pretty useful and complete, but stack trace is uninformative. I'm talking about:

/index.bemtree.js:807:35

It's really annoying moment during usual development

It's not issue of bnsf, it's issue of bem-xjst. May be, with bem-xjst 4.x we'll get better results.
