问题 This question already has an answer here : JSF returns blank/unparsed page with plain/raw XHTML/XML/EL source instead of rendered HTML output (1 answer) Closed 4 years ago . I'm trying to make a very simple couple of HTML pages with JSF, to search for something in a database, but for some reason, when I hit the submit button, nothing happens.

What I want to do is to set the activeIndexes of it. <p:accordionPanel multiple="true" activeIndex="#{myController.getActiveIndexesForSections('whatever')}"> // bla bla... </p:accordionPanel> And the (simplified) method in the backing bean: public String getActiveIndexesForSections
