Automatically update readonly fields upon adding a new repeating section?

With the current setup I have, when a player opts to add a new repeating row, the readonly values within that are placed with their default values and not their calculated ones. How would I go about addressing this issue?

I'm nterested in this as well. There doesn't seem to be an event for attribute creation.

I think the problem is that a new repeating row does not really exist until you create an attribute within it by changing something. I think that the earliest time that you can do calculations is the first time any input in the row is changed.

Yep, that's what I'm doing atm, but was hoping for a better solution.

Until you change a value to trigger the readonly field's calculation, all of the other fields will be their default values, too. Why not make the readonly field's default equal to what your calculation would  produce with default values for all the other fields...?

Can't speak for Justin, but in my case, it's because the fields are affected by multiple other fields (in and out of the repeating section) that have a wide (sometimes essentially infinite) range of possible values.

Basically, what I'm trying to do is implement a weapons repeating section for players to add their weapons with their associated attack and damage rolls using the Pathfinder system. I have a dropdown menu to specify which ability score the attack bonus will be based off of (STR, DEX, CON, INT, WIS, CHA), but the default for a newly created section is STR, and the problem is that it does not update the attack bonus readonly field, which is just set to 0 at creation. So you have a newly created row with STR selected as their ability score, but an incorrect 0 in the attack bonus readonly field. I know I can circumvent this dilemma by throwing in a "null" default value for the ability score dropdown box (something like a "---" value), but I was just wondering if there actually was a way to address this before I did that.

Can't you have the mod calculated outside of the repeating section and then just use that attribute as the default value within your attack?
