Problem with dynamic title in summary

I created a global variable [title] (dynamic title) In onGroupBy event I test sc_get_groupby_rule () to put the related title in global variable [title] witch is defined out and session. Summary is displayed in a new window.
When i change the groupby, the title does not change, i must go back to the window details and return to the summary for the changes appear.
thank you to enlighten me.

Hello,

Could you elaborate on the issue? Perhaps tell me a few steps on how we can reproduce the issue?
