What is the best way to clear all the nodes out of a dataset?
I have a view that uses a dataset to dynamicly load images. The users
sees a Category buttons on the screen. Clicking on a button should
clear all the nodes from the dataset and re-populate it with the new
nodes for the images in the category that the user clicked on. If the
category buttons are clicked to fast they just stop working and I
can't figure out why. It appears as though it's something to do with
how the clearing of the dataset is taking place.
Code:
<library>
<class name="myView" extends="view" visible="false">
<event name="category1ButtonClicked" />
<event name="category2ButtonClicked" />
<dataset name="categoryImageData"></dataset>
<button name="category1Button" text="Category 1">
<handler name="onclick">
parent.parent.category1ButtonClicked.sendEvent();
</handler>
</button>
<button name="category1Button" text="Category 2">
<handler name="onclick">
parent.parent.category2ButtonClicked.sendEvent();
</handler>
</button>
<view name="categoryImagePanel"
datapath="local:classroot.categoryImageData:/*">
<image datapath="@src" />
</view>
</view>
<method name="clearImagePanel"><![CDATA[
categoryImageData.childNodes = [];
]]>
</method>
<method name="addImage" args="imageSrc"><![CDATA[
var imagePointer = categoryImageData.getPointer();
imagePointer.addNode("image", null, { src:imageSrc });
]]>
</method>
