[jira] [Resolved] (TAP5-1703) Remove need for @Persist with
AjaxFormLoop
[ https://issues.apache.org/jira/browse/TAP5-1703?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Geoff Callender resolved TAP5-1703.
-----------------------------------
Resolution: Invalid
I've found a way to avoid @Persist to track removals. It will be in JumpStart 5.7.0 (to be released in a few days time).
Nonetheless, I think AjaxFormLoop would be much simpler to use if, on submit, it returned a list of the removed rows and a list of the added rows. After all, the client side knows exactly what you've done, so why should the server-side have to jump through hoops to figure it out? I'll raise an issue for that soon.

> Regarding use of a submitted AjaxFormLoop, ie. no database changes until submitted; I have almost succeeded in avoiding the need to use @Persist, but I still need @Persist to track the removal of original rows.
> You can see in this example that @Persist IS NOT needed to track added rows, nor removal of the added rows, but it IS needed to track removal of original rows:
> http://jumpstart.doublenegative.com.au/jumpstart/examples/ajax/formloop1 (true as of JumpStart 5.4.21)
> Perhaps AjaxFormLoop could keep a list of the removed original rows in their encoded form and return it through a parameter on submit?
