I've built a multistep webform with page breaks component and several fieldset components on each page/step. Everything is working fine, except that I'm getting the following warnings for each fieldset component, that is NOT on the current rendered page/step, which is defined by the Page Break component:
Warning: Invalid argument supplied for foreach() in element_children() (line 6370 of /home/somesite/public_html/includes/common.inc).
Btw. the error appears in the frontend (not in the backend e.g. when adding a fieldset component).
Does anybody have the same problem/warnings? What could be wrong with the fieldset component rendering?
