I have had no success setting key-hash-proc and key-equality-proc for a {Set-of } even when predefining as constants as per the docs for ChartDataSeriesSet

Is there a known issue?

The compiler reports that Applet already defines key-hash-proc or complans that the proc passed is not a compile-time constant.

The docs contain no working example of a set of user-defined instances using declared hash and equal? as described in the {Set of } docs

A reply would be much appreciated as I should be able to use {difference } and {intersection } to handle my sets efficiently.

thanks in advance for any assistance ...

Contrary to the Doc's

This Type is simply a convenient shorthand for:

{Set-of
ChartDataSeries,
key-hash-proc = ChartDataSeries.hash,
key-equality-proc = ChartDataSeries.equal?
}


THAT CODE GIVES ERROR Argument [proc ChartDataSeries.hash] to Set-of is not an immutable value

It is in fact required to use a {define-proc } wrapper as a work-around, is it not ?

It does look like class proc's do not work for parametrized class parameters, even though I would expect them to work. As you say, putting the code in a top level define-proc (not inside a define-class) will let that work, as would wrapping the call to the class proc in a local {proc}.

Hi

Is there any chance of fixing the '#' anchor behavior for Curl links ?

At the moment it almost prevents Curl applets at height=100% in HTML as the navigation is crippled unless a link is left exposed in HTML.

thanks

Another work around is to call the function before using it in the parameterized type expression, that seems to get it to be converted into a proper proc.
