Hi, this is my first post.  I used the IRC channel freenode#umbraco to some good effect on my last Umbraco project, but there's really not much activity at this point, so I've stopped in here :)  I invite everyone over to the IRC channel if you're interested in semi-realtime Umbraco chat.  My nick's nottwo. 

Thanks!  On to my current issue:

I have a macro called ListProducts that has a boolean parameter called AllBrands and I call it from a document masterpage with:

<umbraco:macro alias="ListProducts" AllBrands="[$AllBrands]" runat="server" />

Either in that document or one of its ancestors is a checkbox field called AllBrands.

In my macro, I test the value of /macro/AllBrands and modify its behaviour.  I've found that when the document or its ancestor has the AllBrands checkbox checked, the macro parameter comes in as '1'.  If the AllBrands checkbox is not checked, /macro/AllBrands comes in as '[$AllBrands]', when I expected it to be either 0 or the empty string.

I've tried modifying the macro call to try to provide the empty string as a default if AllBrands is not checked, but /macro/AllBrands still holds the value of the unreplaced macro parameter string. In fact, giving a non-empty alternate replacement string also isn't passed to my macro. I still get '[$AllBrands]' passed to my macro when AllBrands is not checked anywhere in the node tree:

<umbraco:macro alias="ListProducts" AllBrands="[$AllBrands]," runat="server" />

<umbraco:macro alias="ListProducts" AllBrands="[$AllBrands],foo" runat="server" />

Is this the expected behaviour?  I can test /macro/AllBrands against the value '[$AllBrands]' (and that's what I'm doing, for now), but this doesn't seem quite right.  Any thoughts would be welcome.

Thanks!
