Hi Udo,
sorry... I forgot the environment information:
MyFaces 1.1.6
Tobago 1.0.24 and 1.0.27
The bean has session scope.
<managed-bean>
<managed-bean-name>tobagoTreeTestBean</managed-bean-name>
<managed-bean-class>TobagoTreeTestBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
I have attached my test bean and the jsp page to this mail.
First I thought that the request always contains the state of the navigation,
but I checked the request parameters (using a servlet filter) and figured out
that the state information will only be sent when I click the navigation tree.
Nevertheless reloading the page (browser reload) collapses the tree when using
parameters and saves the state without using parameters. In both situations
there are no request parameters from the navigation state.
--------------------------------------------
Request parameters using parameters:
--------------------------------------------
Parameters:
param: 123
--------------------------------------------
Request parameters without parameters:
--------------------------------------------
Parameters:
--------------------------------------------
Request parameters when clicking the tree:
--------------------------------------------
Parameters:
_idJsp0::form-action: _idJsp0:nav:Number1
jsf_tree: 5
_idJsp0::action-position: 0px,0px,0px,0px
_idJsp0::context-path: /Tobago
jsf_viewid: /TobagoTreeTest.jsp
_idJsp0::form-clientDimension: 913;700
_idJsp0:nav: ;Home;Number1;
_idJsp0:nav-marker: _idJsp0:nav:Number1
tobago.dummy:
_idJsp0:nav-scrollPosition:

Alf
