Problem with auto forward in nested groups of 3-levels deep (Struts/UIX)

Question

Hi all,
In my time registration applications I use master-detail relations of 3 levels deep: Weeks - Days - Hours.
For user convenience I forward directly from the Weeks table page to the DaysHours master-detail page, skipping the Weeks detail page.
Therefore I replaced the forward-on-success-path to the WeeksPage with the WeeksDaysRouter, as if the user selected it manually in the WeeksPage.
This works well, including getting the propper dataobjects and dataobjectsets of all levels.
However when I browse to the next Day in the DaysHours master-detail page using the '>'-button, the server responds with the next week in a WeeksPage.
It seems that the application turns into another state when a user action is simulated in the struts config.
It is unclear to me how to configure the controller to exactly simulate the user action. Who else is in control here? According to MVC I would not expect controlling behaviour in the UIX views.
Can somebody help?
kind regards,
     Martijn

Martijn,
In formPage.uit, the template used by your page that includes the brow2sebuttons, you can find the following line:
<formValue name="targetGroup" data:value="jhsPreviousForward@jheadstart:sessionData"/>
The problem is that jhsPreviousForward still points to the weeks group. You can do two things to solve this:
1. put a custom Struts action in between that changes the value of jhsPreviousForward to "DaysHours" (assuming that is the name of your group.
The code to do this in your Struts action:
sessionData.setAttribute(JHS_PREVIOUS_FORWARD,"DaysHours",SessionData.SESSION_SCOPE);
See chapter 2 of the Dev Guide for more info on writing custom Struts actions.
2. Make a copy of formPage.uit, rename it and change the targetGroup formValue to
<formValue name="targetGroup" value="DaysHours"/>
and have your page use your custom template instead of formPage.uit.
I would favor the first option, you could even make this action generic by passing in the targetGroup name using set-property in the struts-config, rather than hardcoding it in the action.
