@org.omnifaces.cdi.ViewScoped invokes @PostConstruct on unload of an already destroyed view

I have a problem working with @org.omnifaces.cdi.ViewScoped and multiple tabs: I have a link in TestPage.xhtml that opens another page (ShowValuePage.xhtml) with a request parameter "someValue". If I open this link 10 times in a new tab and navigate away in the first opened tab, PostConstruct will be called again instead of just navigating away. Same happens if I navigate back from ShowValuePage to TestPage multiple times. (To test this, we must click the links "Show Value" and "Home" multiple times). This only happens if more tabs are opened than defined in the web.xml values

I am having the below managed bean. But every time I do a post back to the same bean ie while calling updateFileList. I get a new instance of FileDAO. How can I prevent this?

I can't use @SessionScoped but it's a bad practice IMHO. Or maybe save only this one variable into session who knows. Can you guys give me
