[mapguide-users] fusion task pane oddities

[Jackie Ng]

Hi All,

I'm in the process of porting one of our existing mapguide applications to
the fusion framework, and am having difficulties with the new task pane
widget. 

Our application starts from a query panel, which then does a POST query to a
query results page. Clicking on a query result then navigates to a detail
page which displays detailed information for that particular record (and
does some spatial queries on the current map). Once there, there is a link
to go back to the query panel.

Under the existing AJAX viewer, the back/forward buttons would correctly
pick up these navigation changes. The fusion task pane widget does not seem
to function this way. A cursory glance at the task pane widget code reveals
a function called setContent(url). 

Should I be calling this function everytime I want to navigate? If so, does
that mean I am unable to do direct form POSTs if i want the back/forward
buttons to pick up the navigation changes?

Secondly, switching the maps resets the task pane back to the inital url w/
parameters for the current map (it's MAPNAME) which is good, but the task
pane seems to retain the navigation history __before__ the map change
__including__ the parameters of the __previous__ map.

For example, say I have a fusion layout that has MapA and MapB, and it
initially loads MapA, and the initial task url will contain MapA's MAPNAME.
Say I do a few searches and then switch to MapB, the task pane will
correctly load the initial url with parameters for MapB (MapB's MAPNAME). 

But if I hit the home button on the task pane, it will load the initial url
with MapA's MAPNAME, and as a result, any feature operations I would be
performing on the current map (MapB) are actually done on MapA

So in a nutshell....

1 - Should I be using the task pane's setContent(url) to navigate between
pages inside the task pane.
2 - Should the task pane reset its navigation history when the current map
changes? If not, can I force this behaviour?
