Code to run a table mass action from a button?

Just to make sure I understand, are you trying to run an action across all the rows in a model?

Yes. I can add as a mass action on the table (and have)… just wanted to attach it to a separate button

What does the action do?

triggers a salesforce flow

Did you want the button to only run the action on the rows the user has selected, or does it assume they want to run it on all the rows in the model?

all rows on model be good

Sweet, that’s actually easier to do than trying to figure out what the user had selected. The design is something like this:

1. On your Model, add a UI only checkbox (I'll just refer to this as UI_Check)
2. On your Model, add an action When row in model is updated. For the updated field select UI_Check. 
3. In that model action, add the Data Source action.
4. On your Button, add an action that Updates a field on a row. Select your Model and the field UICheck, and have it update all rows in the model.

Fantastic work around!

Thanks Matt

No problem, hope it works out

Working on modifying this action framework for transferring all row data between models. But it seems like Model-based actions wont’t recognize the row context and instead replicates the first row’s information. 

Safe to assume I’m going to have to use a snippet to properly transfer each row’s information to my destination model? The use case is transferring all OpportunityLineItem rows into our Datasource model so we can post to an external data source.
