haskell - yesod devel compiles after change, but doesn't actually reflect change -


this happens in handlers, example, have simple handler edit in vim:

getlistingr :: handler html getlistingr =   defaultlayout $     settitle "thing"     [whamlet|<p>content|]

yesod devel launches server, , serves this.

but then, when change settitle call (not quasiquoter, literal string), server process recognizes change, starts recompile, , serves "wait while recompiling" page.

but when finished, goes serving old content.

i said 'sometimes' earlier because doesn't seem pick newest changes on fresh yesod devel launch. cabal build seems pick changes.

i running ghc 7.10.1, in cabal sandbox locked stackage nightly.
