Tree leaf is still not selectable
---------------------------------
Key: TAP5-1911
URL: https://issues.apache.org/jira/browse/TAP5-1911
Project: Tapestry 5
Issue Type: Bug
Affects Versions: 5.3.2, 5.3.1
Reporter: Geoff Callender
I can't make a tree leaf selectable. When I click on a leaf there's a
javascript error in tree.js:
function doAnimate(element) {
var sublist = $(element).up('li').down("ul");
var dim = sublist.getDimensions();
tree.js:52TypeError: 'undefined' is not an object (evaluating
'sublist.getDimensions')
var duration = Math.min(dim.height * cfg.ANIMATION_RATE,
cfg.MAX_ANIMATION_DURATION)
new Effect.toggle(sublist, cfg.TOGGLE_TYPE, {
duration : duration,
queue : {
position : 'end',
scope : cfg.QUEUE_NAME
}
});
}
It (sublist) is undefined because I clicked on 'tree_1', which has an 'li' up
from it but no 'ul' down from there:
<li>
<span id="tree_1" class="t-tree-icon t-leaf-node
t-tree-expanded"></span>
<span class="t-tree-label t-selectable">
100 Philosophy
</span>
</li>
I saw in TAP5-1629 that I have to provide a TreeSelectionModel if I want it to
be selectable, and that is what I had done:
<t:tree t:id="tree" t:model="treeModel"
t:selectionModel="selectionModel"/>
public TreeSelectionModel<CategoryNode> getSelectionModel() {
if (selectionModel == null) {
selectionModel = new
DefaultTreeSelectionModel<CategoryNode>();
}
return selectionModel;
}
