 Description  « Hide

Here's the problem.

Greg, now in jmaki.js you have:


  • Load a widget
  • @param widget Object representing widget to load
    this.loadWidget = function(_jmw) {
    // see if the widget has been defined.
    if (_jmaki.attributes.get(_jmw.uuid) != null) { return; }
    var targetName ="jmaki.widgets." + + ".Widget";
    var con = this.findObject(targetName);
    if (typeof con != "function") { logError("Could not find widget constructor for: " + targetName + ". Please make sure the widget constructor is properly defined.", document.getElementById(_jmw.uuid)); }
    var wimpl;

When I do DOM replacement of the table in which the scriptaculous
inplace editor widget instances reside, I'm ok as long as the _jmw.uuid
hasn't been encountered before. The moment I try to load one that has
already been encountered, problems result.

This is new jMaki behavior. This is not a problem on the DynaFaces side.

GM> Hi Ed,
GM> We have an API just for this kind of thing:

GM> See the jMaki clear widgets?

GM> jmaki.clearWidgets(DOM_NODE);

GM> jMaki will find all jMaki created widgets under the DOM node:

GM> 1. jMaki will call the destroy function on the widget. A destroy
GM> function is not required but if present will remove any listeners and
GM> make sure data is synced up.
GM> 2. The widget will be div will be removed from the document.
GM> 3. The widget will be removed from the jmaki.attributes map.

GM> If you can call this before re-injecting new widgets your problem
GM> should go away. I think this is the best approach because it give the
GM> widgets the opportunity to de-register events as well. This API has
GM> been around for a few releases and is what the injector uses.

GM> Let me know if this will work, otherwise we will figure out another
GM> solution.

Mark as invalid because clearWidgets() was being called.
