By the way I am using jbpm-jpdl-3.2.G.A. So Start State "Siparis hazirlama" has a variable musteriAdi and Task Node "Siparis onaylandi mi?" has the same variable but can't change its value.
Here is processdefinition.xml.
<?xml version="1.0" encoding="UTF-8"?>
<process-definition
xmlns="" name="Genel stok takibi">
<swimlane name="sekreter">
<assignment expression="group(sekreter)"></assignment>
</swimlane>
<swimlane name="genelmudur">
<assignment expression="group(genelmudur)"></assignment>
</swimlane>
<start-state name="Siparis hazirlama">
<task name="Siparis hazirlama" swimlane="sekreter">
<controller>
<variable name="musteriAdi" access="read,write" mapped-name="Musteri Adi"></variable>
<variable name="urunAdi" access="read,write" mapped-name="Urun Adi"></variable>
</controller>
</task>
<transition name="" to="Siparis onaylandi mi?"></transition>
</start-state>
<task-node name="Siparis onaylandi mi?">
<task name="Siparis onaylandi mi?" swimlane="genelmudur">
<controller>
<variable name="musteriAdi" access="read,write" mapped-name="Musteri Adi"></variable>
<variable name="urunAdi" access="read,write" mapped-name="Urun Adi"></variable>
</controller>
</task>
<transition name="Hayir" to="Siparis onaylanmadi"></transition>
<transition name="Evet" to="fork1"></transition>
</task-node>
<end-state name="Siparis onaylanmadi"></end-state>
<task-node name="Siparis detaylandirma">
Here is the first xhtml called Siparis-hazirlama.xhtml. This is for "Siparis hazirlama" Start State.
