Hello,
I've got the following flowscript:
function addPromo (text) { var row = wid.promos[wid.promos.length]; row.text.value = text; var button = row.deleteButton; button.onClick = function () { // wid.promos.removeRow (0); // return; var index = button.getParent().getId(); wid.promos.removeRow (parseInt(index)); } }
Simple repeater, each row has a text field and a "delete" button that deletes the row. It works except for row 0! I can delete all the other rows, but whenever I try to delete the first row, nothing happens.
As a sanity check, I added the 2 lines of code that are commented out above, and then all my buttons do nothing.
This does appear to be a BUG, as far as I can tell. I was able to replicate it in /samples/forms/v2/example with a very minor change to forms_flow_example.js (similar to above: changed the 'removecontacts' onClick handler to just call removeRow(0), and clicking the button after that change does nothing, but if I change the index to 1 it works). So I know this has nothing to do with my repeater, or any other screwyness I may have going on in my application. It just looks like removeRow(0) is broken for some reason.
I worked around by using the predicate form of removeRow:
function addPromo (text) { var row = wid.promos[wid.promos.length]; row.text.value = text; var button = row.deleteButton; button.onClick = function () { wid.promos.removeRow ( function (row) { return row == button.getParent(); } ); } }
...and that works fine.
