[Patch] Multiple ways in "via" for turn restrictions trigger "error" when validator is run when it shouldn't

[rickmastfan67]

There is an interchange here in the Pittsburgh area on PA-28 where there is a left entrance ramp and almost immediately, there is a right hand exit and you're not allowed to cut across the highway from that left ramp to exit right away. When I set it up in JOSM, there are two ways between the two ramps (because of a bridge). So, I put the two ways in the "via" area to accomplish this restriction. The Turn Restriction plugin had no problems with doing this. However, when I went to upload, the automatic validation trigger and reported an "error" about "More than one "via" way found" as well as "The "to" way does not start or end at a "via" way".

This is the relation that you can see the problems on: ​http://www.openstreetmap.org/browse/relation/1380836

Now, when I do load the relation in the relation editor in JOSM, the entire route is connected, so I have no idea why I also get that "The "to" way does not start or end at a "via" way" error. And regarding the "More than one "via" way found" one, even the main relation page says you can use more than one way.

Now, I tagged this as the "Plugin validator" encase you can also fix this for people who can't upgrade to the 1.6 Java branch of JOSM. But I'm using r3790 with the validator built in. (so if you want to change the "Component" part, go ahead)

Just thought I would let you guys know of this major validator "error" bug.

The attached patch checks the following:

• exactly one via node
• at least one via way
• via node/way not intermixed
• via ways are connected among themselves and with from and to way (takes oneways into account)
• _v2: via node is connected with from and to way (takes oneways into account)

The problem here is, that drawing code and validator are in sync. When we change validator, the drawing must also be changed.
