QueryCrumbs history missing profile attribute #24

Closed schloett closed 9 years ago

schloett commented 9 years ago

Sometimes, querycrumbs fail due to a missing profile attribute. However, I could not yet figure out, when exactly this occurs / how to reproduce the error.

happens for me to. Exception:

After digging deeper: The query object provided to addVisualNode is Null. i guess some unfinished query has been pushed to the query crumb history?

seemed to be a problem of storage handling in the chrome extension, therefore closing this issue and referencing https://github.com/EEXCESS/chrome-extension/issues/49.
