empty controls show up after setwirevalue in collection-performance (forms sample)

[freya]

When pushing the 'setWireValue' repeatingly on collection.performance in the forms sample, once in a while (quite often, in fact) a empty line shows up: a table row where the values are not set.

I'm still seeing this problem, both in FF and IE. You do have to push the setWireValue button quite often though to get an empty line.

This script helps to reproduce the problem:

      $(function() {
        var tint;
        var tmax = 100;
        var tcount = tmax;
        var t = function() {
          $("#loadNativeSampleData").click();
          $("#form1 input").each(function() {
            if (this.value=="") {
              debugger;
            }
          });
          if (--tcount == 0) {
            alert('Button click simulated ' + tmax + ' times. Stopping simulation.');
            clearInterval(tint);
          }
        }
        tint = setInterval(t, 0);
      });

Using this script I can reproduce the problem on

• chromium 6.0.472.63 (Developer Build 59945) Ubuntu 10.10
• Mozilla/5.0 (X11; U; Linux i686; nl; rv:1.9.2.11) Gecko/20101013 Ubuntu/10.10 (maverick) Firefox/3.6.11

(I didn't try IE)

(In [1757]) Properly clean up element index when removing

fixes #321

[karel]

[1757] removed the 'removeChildById' method, but it is still used in the collection control

[mpo]

I scanned the code but can't find this extra lingering reference to removeChildById
Am I missing something?

[karel]

Fixed in r1766, see #386

(Hint: found this using git log -SremoveChildById?)
