Hi Andrew,
Thanks for your help.
You are right the problem is with the treedata. It was null and while
<t:tree2 id="clientTree" value="#{accountTreeBean.treeData}"
accountTreeBean.treeData method was throwing nullpointer exception. Bcas I
was not setting the the accountTreeBean in request which now I am doing
explicitly in one of my action class which take cares of tree creation by
calling accountTreeBean.createTree().
And my managed bean "accountTreeBean" entry will not make any difference
bcas I m calling action class method to bring that tree.
<managed-bean>
<managed-bean-name>accountTreeBean</managed-bean-name>
<managed-bean-class>com.ml.ffogo.csin.web.beans.AccountTreeBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
Hope you understand my problem and thanks alot for your valuable time.
Regards,
Novin
