[HtmlUnit] HtmlUnit: suggestion on the Frameset problem # 753776

[johanholtman <j.h...@so...>]

Hi, 

I posted the "bug" about the frameset: # 753776. 

I'm new to the HtmlUnit software, dived into a bit, and saw a few things
that may help solving this problemen. Can anyone verify this? 

I added a simple HTML example (in the bug spec) so the reproduction is
easy. 

As far as I can see in the HtmlAnchor object code is that the TARGET
attribute value is not used in the click(). I think the target should
influence the currentWebWindow, because that's the window that will be
refreshed. 

Does this help in the HtmlAnchor.click(): 
  0. save the old frame: previousWebWindow = webWindow // see point 4
  1. retrieval of the target webwindow via the frame name: wc =
webClient.getWebWindowByName( targetName)
  2. setting the current webwindow: webClient.setCurrentWindow( wc) 
  3. doing the rest of the click() 
  4. in the Webclient on line 317 could the oldPage be retrieved from
the previousWebWindow (point 0). 

NOTICE: 
The same applies with an enclosing base/target tag. I think the target
attribute of the base-tag is not used in the HtmlAnchor.click(). This
could be done by checking within the HtmlAnchor object if it has a
parent DOM object being a HtmlBase object with a specific target.
