I need a row submit action, that allows a form to be submitted for a specific line in a repeater.
An example usecase would be on a selling site, you have a repeater showing purchasable items, each with a 'buy' button next to it.
Clicking on a row submit action will submit the form and allow the flowscript code that deals with the submitted form to gain access to either the repeater row object, or at least the row index that was clicked.
Is there anything like this already? Any of you interested in adding it ;-)
Use a wd:submit widget (or wd:action) as child of the repeater. In its event handler you can get the repeater row by getting the parent of the submitted widget:
event.getSourceWidget().getParent()
using getId() on it will return the row number (as a string). You can access other widgets on the repeater row by using the getWidget(id) method on it.
Thanks for this. What I've done is extend the RowAction to give it a 'submit-row' action-command. I've added a property to the repeater for it to store and access the 'submittedRow'. When the submit-row RowAction is clicked, it sets the submitted row on the repeater. Then from flow, the submitted row can be found from flow using form.getWidget("repeatername").getSubmittedRow().
I would rather not do it in an event handler, as I'd have to store the row somewhere for future use outside of the forms flow.
Is this reasonable? Is it a reasonable patch?
IMO, it's better to go through the widget that triggered the submit than asking to the repeater (furthermore, what happens in the case of nested repeaters?).
I you want this to be handled by the flow, The Form object provides a getSubmitWidget() that gives the submitting widget. From there, you can use the same getParent() as outlined by Bruno to access the row, and then the row id, child widgets, etc.
