Is there a way to RECREATE the Page Flow Overview in BEA Workshop 4WL?

Question

BEA Workshop foe weblogic makes JSP development a lot simpler, and the auto generated Page Flow Overview is a nice feature - as long as your page flows are relatively small and simple. It doesn't take much to completlly confuse the tool though and you end up with a workflow with all sorts of flow lines cris-crossing each other - often I which I could just reach in and move a single jsp or action item and the whole mess would straighten out.
Is there a way to reposition individual elements of the Page Flow Overview or failing that to have it Recreate itself (in hopes that it will straighten out the mess itself).
Also is there a way to manually edit the flow - adding notes and/or objects and flow lines?

Answer 1

There is no explicit "refresh" button for the Page Flow Overview (PFO), however clicking the "Show Link Labels" button on the toolbar will cause the graph to be redrawn.
That said, in my experience replotting the graph nearly always arrives at the same layout. While the layout algorithm does a pretty good job with large graphs generally, some very highly connected graphs can be pretty tough to read right off the bat.
For various reasons we've moved away from having users manually tweak the layout to deal with this situation. However, we added some highlighting functionality to help make graphs easier to read even if the layout appears tangled.
If you click the Graph Tracing button on the PFO toolbar you can select a given node and see all directly connected nodes highlighted. If some of the directly connected nodes are far away on the canvas, park the PFO next to the Page Flow Editor view and you'll be able to see a more regular arrangement of the same nodes.
When you're more interested in following a specific path than seeing the whole immediate neighborhood, you can hit the slash key repeatedly to cycle through highlighting all the links connected to the selected node.
Finally, you can ctrl-click to multi-select links of interest if you want to trace a given path all the way through the flow. If you were doing this for documentation purposes you can print the graph in this state, or click the Export to Image button, to make a copy of the highlighted path.
WRT your other question about editing the flow - the Page Flow Editor is intended to complement the PFO as a means of efficiently editing the flow. Select a node in the PFO and you be able to add/modify connections to that node viat the Page Flow Editor.
There is no provision to add notes or other objects to the flow (though the exported image files can of course be annotated in a graphics editor for documentation purposes).
I hope that helps.
