Hi.
I have this container:
var layout = new qx.ui.layout.Grid(4, 4);
layout.setColumnFlex(1, 1);
layout.setColumnFlex(4, 1);
layout.setColumnMinWidth(3, 20);
this.__fieldsContainer = new qx.ui.container.Composite(layout);
At some point, I add widgets to it. Later on, I try to remove them, in order to
add fresh controls to it, like this:
var children = container.getChildren();
while(children.length > 0)
children[children.length - 1].dispose();
The removal works without problems. However, later on, when executing the same
code I executed earlier on to fill the container, I get an odd error with a
stack trace comming from deep within qooxdoo itself:
Line 10748 of linked script http://localhost/folder/script/myapp.js

'column' must be defined!");

The code which adds the new controls is executed in the same thread as the code
clearing the container, and finishes OK. The error happens later on, when the
rendering happens, it seems, so I cannot trace the error back into my code.
Unfortunately, this time I also don't have time to run the source build with
test data to see what happens.
Any ideas?
