evaluate expression is getting called twice
I am using WebFlow 2.0.3.
I have defined my main.xml webflow and have one view state, and on "evaluate expression" I am calling one java function to execute.
<view-state id="addProgramme" view="addProgramme">
<transition on="saveData" to="programmeDetails">
<evaluate expression="progController.zulCreateProgramme(exte rnalContext,programmeDVO)" result="flowScope.programmeDetails"/>
When I am calling transition "saveData" it is executing its "evaluate expression" twice.
please, any help for this?
Thanks a lot in advance for your help
