Hide the FPM Page Master in OVP

Hi all,

I have an OVP with a Page Master and a toggle button for manually collapse this page master.

My requirement is to make automatically invisible the page master area when the user click on a certain row in page master.

I tried to raise an 'FPM_TOGGLE_PAGE_MASTER' event and to change the status of toggle button with io_ovp->change_toolbar_toggle_button method but it doesn't work. My code is here below.

Any help?

Thank you,

Francesca
