Topic URL parameter overwrites revision to which REVINFO variable refers

REVINFO variable can be used to obtain revision info of some certain topic. For example:

%REVINFO{topic="TestDocumentA" rev=6 format="$rev" }%

returns the revision number of the topic TestDocumentA.

You may also have a topic, which contains revision info about another topic.For example, the TestDocumentB may have following content:

%REVINFO{topic="TestDocumentA" rev=6 format="$rev" }%

This works fine if you have the latest revision of TestDocumentB open. However, if you open the TestDocumentB topic through url

http://blahblah/TestDocumentB?rev=6

, where rev defines the revision, the revision info for the another document is printed wrongly. The URL's rev parameter seems to overwrite the REVINFO rev parameter.

Example

Content of TestDocumentA (rev5):
This is test.

Content of TestDocumentB (rev6):

%REVINFO{format="TestDocumentB revision: $rev" }%

%REVINFO{topic="TestDocumentA" rev=5 format="TestDocumentA revision: $rev" }%

And now if the TestDocumentB is open normally the output is:
TestDocumentB revision: 6
TestDocumentA revision: 5

But if the TestDocumentB is open from url http://blahblah/TestDocumentB?rev=6 specifying the revision of the TestDocumentB to be 6 the output is:
TestDocumentB revision: 6
TestDocumentA revision: 6

I think this is bug since revision of the TestDocumentA should have been still 5.

Thanks you for the thorough bug description; it really helps!

The problem was due to the url parameter overriding the tag parameter, as you surmised.
