v1.0.0-beta.13-nightly-852: collectionRepeat Performance Issue Caused by the Wrong Size Calculation

[dreamershl]

This will defeat the whole performance improvement. The issue is triggered by the event "resize"

1. Switch to another view from a view with collectionRepeat. The new view will display a modal. Then the following code will be called

modalEl.addClass('ng-enter-active');
ionic.trigger('resize');

2. Because of the event registration "ionic.on('resize', rerenderOnResize, window)" in collectionRepeat the following code will be called in the condition (secondaryScrollSize = 0)

   collectionRepeatManager.resize();

3. Because of the secondaryScrollSize=0, the function "calculateSize" will believe all the items should be rendered as first item.

The final result is collectionRepeat will render every item in the datasource, which normally will be thousands. This will cause the serious performance issue.

Fixed, thanks for the investigation.
