These warnings have been downgraded to info messages for Wafflecone. Investigating and fixing the actual source of the warning is a 4.1 task.

Changed to INFO in wafflecone as workaround. Cloned and reopened in 4.1 to find the source of the warning.

Hello Amy,

This note is regarding bug ~~LPP-4592~~ which I have tested in r6938.

If I compile this script in swf7 in IE7:

<canvas debug="true" height="300">
    <dataset name="dsComboOptions">
        
        <item value="1">View Source</item>
        <item value="2">Open in Browser</item>
        <item value="3">Mark Unread</item>
        <item value="4">Create Filter...</item>
    </dataset>

    <datacombobox selectfirst="false"
                  itemdatapath="dsComboOptions:/item" />
</canvas>

I get the following Debugger output -- "INFO: __LZgetNodes: p is null in LzDatapointer."

It is an info line, not a warning. However, I _think_ that according to the bug notes, the selectfirst attribute should be set to "true" for this warning to trigger, correct? If I set it to 'true', I get no error on compilation; when I set it to 'false' I get the info line.

The short description and the full description do not match.

I have verified the info message is triggered when the selectfirst attribute is set to false, as opposed to a warning being triggered.
