why dont you create a custom renderer that uses the custom template instead of the other way around?

Jack,

Depending upon your needs, a model ui field with an ‘if’ and ‘model lookup’ should work as well.

Thanks,

Me things you will need to create a second custom renderer.  Choose some other random field on your tables model and bind it to a custom renderer that finds the value from the other model and does the calculation and format manipulation you are interested in… 

Getting there! Thanks Bill for reminding me of Model_Lookup, it is working great to pull the value from my other model into my parent table. The one thing I had to remember was to put my other model FIRST in the model order. 

Now that pulling in the data from the other model is working, I can add a custom field renderer to it. I just need to adjust my field renderer. Currently I have a UI-Only formula field that has my logic in it, which is a complex series of if statements comparing the value of a field to a benchmark value. Then my custom renderer looks to that UI-only field and says if TRUE, render cell as red, and if FALSE render as green. 

So, in order to make this scale, I will need to move that IF logic into the field renderer itself, so it can work dynamically. It’s a little harder getting the if/then in Javascript than in the UI-Only formula syntax. 

Thanks everyone!

It is harder to do in Javascript - but so much more powerful…
