Spawning A Fluid

[TricliniumAlegorium]

I am making a generated structure that spawns in with a portal. The portal uses a fluid to light it. When I spawn in the fluid on the inside of the portals border it doesn't create the portal...it is just fluid. I know it works if you place the fluid by hand. How can I spawn in the fluid on the frame as if I had just placed it (which values/metadata) to create the portal?

Ive tried every number combination and cant get it to work...

After you place the fluid, mark the block for update in the world. 

 

Depending on how you placed your fluid, there should be an option to do that if I remember right without the above.

I tried to cause a block update but it didnt work...what method did you use to cause the block update?

Im trying some different methods and still cant get it to make the portal...Im even trying different directions to make it more like the player placed it. I just dont get it...
