Hi again,
after validating my example code for the condition node sharing i found
another problem. if i have 2 rules with 2 conditions and the first condition
of these rules is a shared one (equal), the rete graph will not be complete.
For the second rule there is no JoinNodeInput from the shared condition.
To understand why my code doesn't work i have modified the helloworld
examples to reproduce.
helloworld-java -> helloworld.java.drl
------------------------------------------------------------
<rule name="Hello World">
<parameter identifier="hello">
<class>String</class>
</parameter>
<parameter identifier="state">
<class>Integer</class>
</parameter>
<java:condition>hello.equals("Hello")</java:condition>
<java:condition>state.intValue() == 1</java:condition>
<java:consequence>
helloWorld( hello+" 1" );
</java:consequence>
</rule>
<rule name="Hello World2">
<parameter identifier="hello">
<class>String</class>
</parameter>
<parameter identifier="state">
<class>Integer</class>
</parameter>
<java:condition>hello.equals("Hello")</java:condition>
<java:condition>state.intValue() == 2</java:condition>
<java:consequence>
helloWorld( hello+" 2" );
</java:consequence>
</rule>

The RETE-DUMP for these 2 rules:

If i do the same within the HelloWorldNative.java it doesn't work.

On the images generated by GraphViz from the ReteDotDump it is easier to
see. I can send them on demand. Also the modified HelloWorldNative.
Sorry for the large text, but i hope this helps to understand my problem.
Thanks & Regards
