PMPHandler - PropertyManagerPageButton disappear

Hi all,

I'm building a custom Property Manager Page, with multipage that I'm correctly able to manage using visibility on PageGroups depending on previous/next buttons.

During the next/back "workflow" sometimes happens that I come into a PageGroups where buttons disappear ... e.g. I'm on a step where pageGroup1 is visible and this group includes two PropertyManagerPageButtons ... than I go on with next button and I show pageGroup2 ... that's ok ... than I go back to previous pageGroup1 and here only the two PropertyManagerPageButtons are hidden (other controls like labels or selection box are still visible) ... I'm not able to reproduce this behavior ... sometime it happens and sometime not ...

This happens also sometime on a single pageGroup where I have 3 PropertyManagerPageButtons ... I click on one of these buttons ... the process correctly remains in the current page, but all 3 buttons disappear ...

Someone experienced similar behavior??

Thanks!
