Re: [xmlblaster] Strange error when unsubscribing

Hi again,

our persistent entries should be marked with capital letters

public static final String ENTRY_TYPE_SUBSCRIBE = "SUBSCRIBE";

which does not match to the type of your logging output:

'subscribe'

I have no idea how this small notation can appear, i believe it must be somewhere
in your database?

I have commited to the current svn a version which ignores case during
persistence lookup, but this is just a temporary workaround,

regards
Marcel

It appears that there is a problem unsubscribing but I am unsure what the problem might be. Any thoughts or hints on how to proceed with debugging this problem?

Thanks in advance, David Robison
