Closed Issues in 6.4.2_HF-009 (This Release)

AMBW-33684
Performance improvement is made for executing the XSLT for the input to an
activity when the mapping consists entirely of a copy of the output of some
previous activity.
For new mappings, the tibex:copyOf extension attribute gets automatically added
to an activity, if the activity’s input binding contains a root level
xslt:copy-of element to improve the performance.
Use the Update activity input copyOf variable repair tool to update existing
mappings in existing projects.

AMBW-33611
Embedded policies were not enforced on the AIX platform, and the exception
NoClassDefFoundError was logged in the AppNode log when you start the AppNode.

AMBW-33610
You can see all of the possible errors at once to understand more reasons for
an application startup failure.
A new property bw.engine.show.all.errors.while.application.startup was added at
the AppNode's config.ini file.
Set the property to true and restart the AppNode to see the changes.

AMBW-33604
An XML To Java activity could not reload newly added Java members in a
Java class.

AMBW-33603
Namespace declaration was missing when type substitution on input of the JMS
Send Message activity was used.

AMBW-33601

when a root element had choice elements.

AMBW-33596

deployment on a Web browser, the file could not be retrieved at run time,

AMBW-33567
The copy-of on root element failed with incorrect namespace.

AMBW-33552

Components view.

AMBW-33544

Get JMS Queue activity, the property JMSXDeliveryCount was automatically

deployment on a Web browser using the URL for the AIX platform.  

AMBW-33382

a browser.

AMBW-33317

AMBW-33224

AMBW-33024

a substitution group.

when a module property was used for the Endpoint URI field in a SOAP service
binding.

AMBW-32544
When an application with shared resource failed to start, after redeployment,
it continued to fail.
