Don Brown updated WW-2669:
--------------------------
Fix Version/s: 2.1.3
> Autocompleter options list element does not resize correctly
> ------------------------------------------------------------
>
> Key: WW-2669
> URL: https://issues.apache.org/struts/browse/WW-2669
> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - Dojo Tags
> Affects Versions: 2.1.2
> Reporter: Aner Perez
> Fix For: 2.1.3
>
>
> The sx:autocompleter has code in place to resize the div which contains the
> options based on the number of items in the list.
> The div starts out at 120px by default but if the list of items uses less
> than 120 pixels, it resizes the div to fit the available data (i.e. makes it
> smaller).
> The problem is that the code never expands the size of the div if the list of
> items grows once more. If you have an autocompleter which starts out with 1
> item in it, the div (once displayed) will be resized to fit 1 item. If you
> refresh the list of items in the autopcompleter to have more than 1 item, the
> div is still displayed with a height appropriate for 1 item. This makes it
> seem like there is only 1 item in the list.
> The offending code is at line 529 of
> src/main/resources/org/apache/struts2/static/dojo/struts/widget/ComboBox.js :
> ---- original code ---
> var totalHeight = this.itemHeight * childs.length;
> if(totalHeight < this.dropdownHeight) {
> this.optionsListNode.style.height = totalHeight + 2 + "px";
> }
> --- original code ---
> This should be:
> --- fixed code ---
> var totalHeight = this.itemHeight * childs.length;
> if(totalHeight < this.dropdownHeight) {
> this.optionsListNode.style.height = totalHeight + 2 + "px";
> } else {
> this.optionsListNode.style.height = this.dropdownHeight + "px";
> }
> --- fixed code ---
> Now the div correctly handles the height increase when more items are added
> to the list.
