xbl thinks method is not a funtion
Marja Koivunen
but having problems.
What can be wrong when I get:
************************************************************
* Call to xpconnect wrapped JSObject produced this error: *
[Exception... "'[JavaScript Error: "this.growTopicTrees is not a function"
{file: "chrome://ubimarks/content/topicSelectionTree.xml" line: 120}]'
when calling method: [nsIDOMEventListener::handleEvent]"
nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)"
location: "<unknown>" data: yes]
************************************************************
This is the binding. It doesn't matter is I use the constructor or the
handler or
loadBindingDocument() function.
I used to call viewCommonTopics() with load event handler connected to a
window and it still does call this function.
However the growTopicTrees function is not a function anymore...
<binding id = "ubiSelectTopicsTree">

<xul:splitter/>
<xul:treecol id = "selectedCol"

cycler = "true"/>
