The following replacement for the IsFishingPole function makes it work for all known poles as well as any poles added in future patches:

local function IsFishingPole()
	local slot = GetInventorySlotInfo("MainHandSlot")
	local link = GetInventoryItemLink("player", slot)
	local _, _, _, _, _, _, itemSubType = GetItemInfo(link)
	return itemSubType == "Fishing Poles"
end

Cambri4's modification to r81 seemed to work. However when I switched the 2 weapons on my rogue the addon triggered and thought my char was in 'fishing mode', turning off music etc. Equipping fishing pole and un-equipping didn't help.

I simply love FishingAce!
But since my recently acquired Jeweled Fishing Pole didn't work with FishingAce r81 either, I started to investigate..
The new fishing poles don't seem work with FishingAce because it checks the icon name of the equipped mainhand item. Blizzard started using new icons for fishing poles, so it doesn't recognize the new fishing poles introduced in 3.1.
In order to solve this problem, I took a different approach to the fishing pole recognition.

First of all, I added a new table including the ItemIDs of every fishing pole in the game.
You could add this before the FISHINGLURE table

local FISHINGPOLES = {45992,45991,45858,44050,25978,19970,19022,12225,6367,6366,6365,6256}

The main changes are in the IsFishingPole() function.
Just swap this with the old function.

local function IsFishingPole()
 local slot = GetInventorySlotInfo("MainHandSlot")
 local link = GetInventoryItemLink("player", slot)
 local _, id, _ = SplitLink(link)
 for i,val in ipairs(FISHINGPOLES) do
  if (string.find(id,val)~=(nil)) then
   return true
  end
 end
 return false
end

Instead of comparing the Icons, it compares the ItemIDs.
This way FishingAce can easily be edited for any new fishing poles Blizzard might implement, since you would only have to add the item ID to the FISHINGPOLES table.
The amount of lines of code is actually the same. There might be a more elegant solution, but it suited my needs.
I hope this helps all those lucky enough to acquire one of those fancy new fishing poles. :)

The right click on water to cast seems to be buggy. It won't work with the Jeweled fishing pole. It still works with the Mastercraft Kalu'ak fishing pole. So if I have the Jeweled one on and right click to cast nothing happens. If I switch to the Kalu'ak pole it works. Same thing happens if I go from the Kalu'ak to the Jeweled. No errors pop up or anything. It just doesn't work with the new pole.

Just figured I would post this since you have updated this mod.
