2011 NEWS 2011-10-11 - Various Broken Examples Fixed
Various JavaScript examples on the UIZE Web site that had become victims to bit rot have been restored to their former glory.
1. Broken Styling in Sliders Examples Fixed
A number of the JavaScript examples that use slider widgets (i.e. instances of the Uize.Widget.Bar.Slider class) that had been broken by a change in the state properties mechanism have now been fixed.
The problem with the slider examples was manifesting as incorrect size for slider knobs and incorrect thickness of borders. The cause of the problem was a refactoring of the ad hoc creation of state properties that introduced a subtle but undesirable change in behavior for creating state properties in an ad hoc fashion by setting values for undeclared state properties on the class. The earlier behavior of the state properties mechanism has been restored and unit tests have been written to ensure compliance going forward.
2. Fixed Flickering Issue in IE9 in 3D Rotation Viewer Examples
An issue with flickering in the 3D Rotation Viewer example that was seen in IE9 has been fixed.
The cause of the issue had to do with the use of the displayNode instance method of the Uize.Widget class for showing frames of the 3D rotation. For the 3D frame DOM nodes that were not yet visible and whose display style property was set to none, IE9 was not loading and/or setting up the image object, probably as part of general smart performance optimization of the browser. The negative side effect of the optimization was that the frames would not be immediately visible when rotating to them, causing a one time flickering effect as the view was rotated. Switching to using the visibility style property (by using the showNode instance method of the Uize.Widget class) fixed the flickering issue.
3. Broken Images in Various Examples Fixed
A number of JavaScript examples that were displaying broken images have been fixed, including numerous slideshow examples and examples using image thumbnails.
The cause of the problem was a change in an image API that was being used by the UIZE site. URLs for the broken images have been updated to use the image API's new query parameters and the images now display correctly in the examples. There still remains a couple of examples with images that are broken because of a different issue, and these examples will be fixed in a future release.
