Hi Linus
opens the tiddlers "Test1" and "Test2" as expected. However, when the
> filter is parameterized as follows:
>
> \define openTiddlers(tf)
> <$button>
> <$list filter=$tf$>
> <$action-navigate $to={{!!title}}/>
> </$list>
> Open tiddlers
> </$button>
> \end

The $param$ and $(var)$ syntax results in a textual substitution that is
performed on the macro contents before it is parsed.
The problem here is that the textual substitution occurs literally, so if
you pass a value that contains spaces you'll get something like this:
<$list filter=one two three>
So, the solution is to include quotes:
<$list filter="""$tf$""">
By using triple double quotes we ensure that filters that contain single or
double double quotes will work correctly.
Best wishes
Jeremy.
