518082 - nsIWebbrowserFind entireWord attribute doesn't work when its value is set to True

Status: RESOLVED DUPLICATE of bug 269442

(Core :: Find Backend, defect)

Description

[shum_bin]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)
Build Identifier: xulrunner 1.9.1.3

I am experimenting on xpcom using vb.net, much like geckofx but which is using c#.

The testing application simply navigates to an html file on local disk and perform a findNext() using the nsIWebbrowserFind interface. All attributes of the interface except entireWord are working great. The value of entireWord is set successfully to True. But still the function locates the "is" inside "this" as a match, as if it always uses the value of False.

Because only this single attribute value is not working, it is most likely a bug, rather than an issue with the app.

Reproducible: Always

Steps to Reproduce:
1.need an app embedding mozilla via xpcom
2.navigate to any html file
3.perform a findNext() using nsIWebbrowserFind interface with entireWord=True, searchString="is"
Actual Results:  
finds & highlights "is" inside "this"

Expected Results:  
should skip "this"

The definition of the interface used in the testing app is like this :

<Guid("2f977d44-5485-11d4-87e2-0010a4e75ef2"), ComImport(), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)> _
