Blob storage to file system - Malformed key?

[shoon]

Version: Play-morphia 1.5.0a

I get a warning every time I save a blob in my model:

10:19:51,968 WARN  ~ error load blob by key[MyStoredBlob_53971403a31057eb1c0aefd6]

The file is committed to the file system just fine and I can retrieve it.

The file is in a time stamped directory and has the file extension. I suspect the key fed to the osgl reader is missing the directory or the file extension.

find . | grep 53971403a31057eb1c0aefd6

Pretty sure this is related to #117

[greenlaw110]

#117 closed already, so you mean the issue is still there? Or the fix to #117 caused this issue? Sorry I don't have too much time on play-morphia for the moment

I think the issue in 117 is resolved but there's a section of code that prints out the warning but continues on:

BlobStorageService.java, Line 171

I started a new project recently and wanted to note here how I muted the warning in log4j using StringMatchFilter. Some day will submit a patch :)

log4j.appender.Rolling.filter.1=org.apache.log4j.varia.StringMatchFilter
log4j.appender.Rolling.filter.1.StringToMatch=error load blob by key
log4j.appender.Rolling.filter.1.AcceptOnMatch=false
