Hello Dario,
I'm not sure why your code is not working in 1.5, but I have my suspicions.
Most/all of the examples in 1.5 use OWSContext instead of WMC.
WMC provides a list of WMS layers. OWSContext lists WFS, GML, Cached
WMS, Google Map layers as well. Unfortunately it has a slightly
different syntax, which means it is not backwardly compatible with WMC.
Our MapPaneOL widget should render both WMC and OWSContext files, but it
might not. (Note that the MapPane widget has been depreated - that might
also be your problem).
On another note,
I'm interested to know what your end goal is. Adding filter
functionality to Mapbuilder is a highly requested feature. I'm
interested to know how you plan to achieve this (your design) and
whether you are able to return the code back into Mapbuilder.
Andreas may have more to say - he has been looking into Filters as well.
Of note, manipulating a WMC using a filter, or building a filter should
probably be in a widget or tool rather than in the Context.js. Our
design aim is to keep the model classes small so that other applications
which don't use Filter don't need to include the extra code.
