I have ATG 10.1.2 and Endeca 3.1.1.
I configured Stage and Prod instances of CRS, and I connected them to one Endeca App with 2 DGraphs.
Stage CRS is connected to Authoring DGraph, while Prod CRS is connected to Live DGraph.
Preview in Endeca App points to Stage CRS: http://localhost:8280/crs and http://localhost:8280/crs/link.json (not sure the latter is correct)
Preview works fine when I change something in existing pages, e.g. instead of 12 products per page, I set 10 and clicking Preview button I immediately see the change in opened Stage CRS
But, when I try to create a new page in Experience Manager and preview it, I'm getting the below error:
Can you please let me know , while creating a new page in EXPMGR did u happen to create any new templates to the page which u are creating,If so please add the aapropriate cartridge in ur store.war cartridge folder, this is because when ever a new template of type page or cartridge is create , it looks for the corresponding cartridge handler.
If i am not clear, mention the steps that u are taking to creating a new page in experience manager, ill let u know why this is happening.
