Does somebody has done this integration, spectrum 9.4.2 and REX 11.0.47? I follow a tip to modify config file in $SPECROOT/IPRM/REX directory and still have same error, attach image
I ran into the same problems with Spectrum 9.2.3 and 9.4.0 against RouteExplorer.
Turns out CA only supports _ancient_ versions of RouteExplorer, hence the broken API integration.
I heard some rumours that the Spectrum - IPRM - REX integration were due for an overhaul/fixup in Spectrum v.10.
An overhaul or fix in v10 would be fantastic. I'd prefer to see it taken one step further and have the REX functionality built right in to Spectrum, but that's probably just wishful thinking.
