[TYPO3-english] Strange behavior of felogin and custom template

[Boris Gulay]

I have felogin extension inserted into page. In felogin properties I have
set custom template.

If I change something in this template, this changes will not be reflected
in CMS output until I remove template in extension properties and set it
agein.

Why felogin works with template so strange? If I change template for
formhandler extension I can see this changes in output emmidietly.
