I am not doing things this way. I presented this as a hypothetical case and my question is why is this bad? I mean what problems can we run into using this technique.
Thanks for the write up but I would appreciate something that in more in detail.

I would recommend you another pattern, but I will not going to share my way of doing this until a new version of Struts1 that would allow to turn off automatic reset/populate of a form is released. Why would you create an ActionForm for pure output purposes? You can create a POJO or even access properties of your business object. On a side note, in Struts actions precede pages. An action receives a request and then displays a page. In your case, it obtains information from page1, but it renders page2. Even this is not true. An action does not obtain information from a page, it just receives a request and it does not care where the request comes from. So talking in terms "page1.jsp calls Page1Action" is not entirely correct to me. Therefore I would name your action as Page2Action, not Page1Action, that would be clearer for me.
