[JBoss jBPM] - Error installing JPBM JPDL Designer 3.0.13
by anthony.mcclay
I am unable to upgrade to 3.1 base code.
I am using both MyEclipse 5.5.1 and als a newly downloaded version of Eclipse 3.2.2 and the jbpm-jpdl-designer-3.0.13.zip from the sourceforge download site.
I receive the error when I open the JPL Designer Editor
In both cases I get a null pointer Exception.
Base configuration:
Java Version
C:\Documents and Settings\mcclayac>java -version
java version "1.5.0_14"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03)
Java HotSpot(TM) Client VM (build 1.5.0_14-b03, mixed mode, sharing)
NOTE ( 1.5.0_13 no longer avilaable)
JBPM Designer version:
jbpm-jpdl-designer-3.0.13
jbpm-jpdl-designer-nodeps-3.0.13
FACTS:
#1. I received the following error using both instalations (See Below)
#2. Both versions seem to be dependent on version of Jface
version 3.2.2.M20061214-1200

[JBoss Seam] - Cannot instantitate @Embeddable attribute.
by infoherlinsys
Dear Partners.
The following xhtml piece references two attributes
of an Entity-EJB. The first works fine. The second one is
an @Embeddable attribute but it throws an exception:
"Cannot instantiate MonetaryAmount"
Something is wrong.
Attached is the related code.
If appreciate your advice.
Thank you.
Roger Mori.
