[users@httpd] Query regd JSF

["nimisha sharma" <nimisharma31@xxxxxxxxx>]

Hi,

I am trying to generate a tree table structure using JSF. i did get it, and am using the <t:tree> tag provided by myFaces. Though i am not getting the '+' and '-' navigation signs in the tree. In place of those, i do get an image as if a gif image was supposed to be present there but is missing. 
The tree table is functional.. i.e. i can expand and collapse the nodes properly.. but somehow i m just not getting the navigation signs.
I even tried making a regular tree using the <t:tree2> tag. Here too i faced the same issue even inspite of setting showNav="true". 
Is there a css for this? what are the values to be specified in nodeClass, styleClass attributes in the <tree> tag? How do i get those navigation signs?
Any help in this regard is greatly appreciated.

Thanks,
Nimisha.
