The Grails documentation for the remoteFunction update attribute states:

update (optional) – Either a Map containing the elements to update for ‘success’ or ‘failure’ states, or a string with the element id to update, in which case failure events would be ignored

I’m a little confused why the indicate a Map and not a List here, is this wrong? I imagine I want my remote action to return a Map, where the keys match the name of the list elements specified in the update attribute??

Thanks

    Use update, if you want to replace a part of the current page, which is identified by the (html)-id in the update tag. E.g.:

    <div id="resultOfAJAX"></div>

<g:remoteFunction update="resultOfAJAX" [..] />

    However this is not useful, if the AJAX call fails. That is why you can define which element is to be updated in the failure case:

    <div id="resultOfAJAX"></div>
<div id="someErrorField"></div>

<g:remoteFunction update="[success: 'resultOfAJAX', failure: 'someErrorField']" [..] />

    I am not sure, whether this clarifies your question regarding update, but maybe it helps 😉
