Hi Andi, Dan,
I have another issue with Blob's on 1.16.2. If an action called using RO
interface returns a null Blob I get a NPE. I believe somebody noticed
already because when I look at [1] there has been taken care of this
condition. When the action returns a non null value I get an exception
on [2].
Furthermore retrieving a Blob value from an entity directly using a
query like 'tq.executeResultUnique(Blob.class, true, cand.logo)' (action
called trough RO) is not solved by copying the files you mentioned
before. In that case I get an exception:
Creation of SQLExpression for mapping
"org.apache.isis.objectstore.jdo.datanucleus.valuetypes.IsisBlobMapping"
caused error
Unable to create SQLExpression for mapping of type
"org.apache.isis.objectstore.jdo.datanucleus.valuetypes.IsisBlobMapping"
since not supported
org.datanucleus.exceptions.NucleusException: Unable to create
SQLExpression for mapping of type
"org.apache.isis.objectstore.jdo.datanucleus.valuetypes.IsisBlobMapping"
since not supported
Any workaround for this too? ;-) Are these known issues or do you want
me to raise an issue for these?
Thanks,
Erik

Thanks Erik!
Good to know. Remember, this is just a workaround, we definitely will try to
fix this.
Cheers Andi.

Hi Erik,
strangely we had the same symptoms when working on the coming 2.0.0-M1
release. We tracked it down to the fact, that Isis' datanucleus
extensions don't get installed during bootstrapping.
Would be interesting to see, whether our current workaround [1] (to copy
over 2 files into your domain code) solves the issue. (Please let us know!)
* /plugin.xml
* /META-INF/MAINFEST.MF
As of version 1.16.x these files are in the isis-core-runtime jar file
of the release.
Cheers Andi

Hi,
I'm having troubles with Blob fields after upgrading to Apache Isis
1.16.2 (not sure if this was also the case for 1.16.[0-1]). The feature
is using existing data we had no problems with before upgrading.
My field definition:
@javax.jdo.annotations.Persistent(defaultFetchGroup="false", columns = {
           @javax.jdo.annotations.Column(name = "file_name",
allowsNull = "false"),
           @javax.jdo.annotations.Column(name = "file_mimetype",
allowsNull = "false"),
           @javax.jdo.annotations.Column(name = "file_bytes",
jdbcType="BLOB", sqlType = "BLOB", allowsNull = "false")
       })
   @Property(editing=Editing.DISABLED, optionality=Optionality.MANDATORY)
   @Getter @Setter
   private Blob file;
Caused by: javax.jdo.JDOFatalUserException: StreamCorruptedException:
object is corrupted

java.io.StreamCorruptedException: invalid stream header: 47657370

I've changed the sqlType to "LONGVARBINARY" but this didn't help. I
can't reproduce this issue in the quickstart app. Was there any change
in Datanucleus version? Will have another look at the change logs.
Anyone having an idea?
Thanks,
Erik
