Navigate from a view to a tab

hello, i have a search view where user keys some search criteria and then clicks on a button to navigate to a tab (icontabfilter in a icontabbar). i am using this https://sapui5.hana.ondemand.com/#/topic/cdab0a1123514cc08cf2c8deb22f312e as a guide.

the target seems to arrived at (i can see in debugger that targetMatched) but the view is not display. i tried using setSelectedKey method but target is not displayed.

any help (with example) greatly appreciated.
