Subject: Use DatabaseJob instead of Job to prevent UI from getting stuck
X-Git-Url: https://gerrit.simantics.org/r/gitweb?a=commitdiff_plain;h=b654d9f368d601565303bcf646fc4fbdfbc37090;p=simantics%2Fdistrict.git

Use DatabaseJob instead of Job to prevent UI from getting stuck

The breakdown calculation can take a long time, thus it is better to
reverse the database for that time so that the rest of the UI doesn't
start synchronously waiting for DB access.
