Topology Theme / Advanced Styling - Errors

Question

Hello
We're undertaking some evaluation / proof of concept activities with mapviewer connected to fusion middleware 11g / 11g2 database
Our application would require a topological data model and we have successfully created a small topological testbed.
The topological model can be successfully interrogated in mapbuilder and displays in mapviewer when simple line styles are applied.
There are two problems:
1) when displayed as a themeBasedFOI in mapviewer the topological theme is not clickable so cannot be interrogated (yes all the obvious settings have been tried)
2) the topology theme cannot be combined with an advanced Style (to enable lines to have different styles according to a attribute columns in the topology table)
The styling problem manifests itself as a dialogue box displaying "Error 0" when using mapbuilder and an error "SEVERE: Error rendering FOI image java.lang.ArrayIndexOutOfBoundsException: 0" on the mapviewer console.
As these problems do not manifest themselves when using geometry themes and the topological data seems otherwise to work correctly I'm inclined to think this is a bug in the topology code but would be interested to know if anyone else has experienced / resolved this?

Answer 1

The processing of geometry themes and topology themes are different. The attribute 'rule#0' that you see on the query for geometry themes is something internal of MapViewer that is added on the query. This does not apply for topology themes. You can use advanced style with topology themes. The idea is similar to geometry themes, where you add some attribute to be used by the advanced style. Post the advanced style definition and the topology theme definition that you were trying to use.
