Scheinbar ist doch keine schnelle Lösung für das Ontolica Wildcard Problem mit BDC Web Parts in Sicht:
I got a reply from the developer about the problem you where having with getting the wildcard version to work together with the BDC and this is what he said:
„I can easily reproduce this bug but has so far been unable to fix it.
It seems the SharePoint DBC web parts fail as soon as the Ontolica search box is active on the page. I have tried to strip all code from the search box. But the BDC web parts still fail. I am not sure why they do this but it seems like a bug in the MS web parts that make them very fragile. I am therefore afraid we cannot produce a solution to this problem at the moment. We can try again when MS releases SP1 for MOSS.“
So unfortunately we will have to wait for a solution for you.
