Summary: Create Default Transitions for Dialogs
Product: Struts
Version: 1.2.4
Platform: Macintosh
OS/Version: Mac OS X 10.3
Status: NEW
Severity: enhancement
Priority: P2
Component: Shale
AssignedTo: dev@struts.apache.org
ReportedBy: dgeary@apache.org
We could make defining dialogs much easier with some default transitions. If we
assume that the dialog states in dialog-config.xml are listed in the order they
are traversed, we could provide default "next" and "previous" transitions for
each state, except of course, there would be no "previous" transition for the
first state, and no "next" transition for the previous state. Any explicit
"next" or "previous" states declared in dialog-config.xml would override the
defaults.
It also seems like a common requirement to have dialog-scope transitions (not
state-scope) for each state in the dialog. For example, many wizards have tabs
that let you jump from one wizard panel to the next, regardless of the currently
displayed wizard panel. We could also create default dialog-scope transitions
whose outcomes and targets match the state names. Again, you could override
those defaults by providing your own transitions.
With those changes, we would reduce this:
<dialogs>
<dialog name="Create Account"
start="User Information">
<transition outcome="User Information" target="User Information"/>
<transition outcome="Address" target="Address"/>
<transition outcome="Phone Numbers" target="Phone Numbers"/>
<transition outcome="Summary" target="Summary"/>
<transition outcome="Exit" target="Exit"/>
<view name="User Information"
viewId="/pages/account.jsp">
<transition outcome="next"
target="Phone Numbers"/>
</view>
<view name="Phone Numbers"
viewId="/pages/account.jsp">
<transition outcome="next"
target="Address"/>
<transition outcome="previous"
target="User Information"/>
</view>
<view name="Address"
viewId="/pages/account.jsp">
<transition outcome="next"
target="Summary"/>
<transition outcome="previous"
target="Phone Numbers"/>
</view>
<view name="Summary"
viewId="/pages/account.jsp">
<transition outcome="previous"
target="Address"/>
</view>
<end name="Exit"
viewId="/pages/login.jsp">
</end>
</dialog>
</dialogs>
To this:
<dialogs>
<dialog name="Create Account"
start="User Information">
<view name="User Information"
viewId="/pages/account.jsp"/>
<view name="Phone Numbers"
viewId="/pages/account.jsp"/>
<view name="Address"
viewId="/pages/account.jsp"/>
<view name="Summary"
viewId="/pages/account.jsp"/>
<end name="Exit"
viewId="/pages/login.jsp">
</end>
</dialog>
</dialogs>
