Hi all,
goTo(features) is not working on polines layer:
I have made a little sample to test this, with 2 layers of different geometries, one is points, the other is polylines.
When I left click on map, I execute a Query and then I display result features highlighted, then I goTo() this selection of features. Features are correctly highlighted, but unfortunatly goTo() do not move to a correct place, actually it zooms to a bundle of found features (randomly not always the same from time to time) and if I span to another place faraway and click again to perform the Query, then the highlighting works always fine, but goTo() do not move anymore atall. I can see no JavaScript error, nor in the catch event of the goTo() function.
If I do the same test with a mouse center-click on my example, which performs Query on second layer which is containing points, features are found, highlighted and Zoomed correctly anytime.
Reagrds,
Chris
