Multicategories and Macros

Developers Search Interface

Hi,

 

Struggling to get this to work:

 

https://docs.funnelback.com/help-ftl/funnelback.ftl.html#MultiCategories

 

The descriptor seems to suggest this macro will produce a list of checkboxes so users can select multiple categories.

 

Does anyone have an example of how this fits into the .ftl template - I've been struggling for hours.

 

No problem displaying facet and categories in the normal way - but I can't get this to work at all.

 

Maybe it's a lot more complicated than this and I'm missing something obvious but I'm trying this:

 

                  <@fb.MultiCategories facet="section"/> 
 
I'm getting this error: Expected hash. facet evaluated instead to freemarker.template.SimpleScalar on line 408, column 12 in web/templates/modernui/funnelback.ftl.
 
Any advice appreciated

Still having no luck with this.

 

Can get this to work:

 

<@s.FacetedSearch>
<@fb.MultiFacet name="section">
<h2>Test FACETS CODE</h2>${fb.facet}
    </@fb.MultiFacet>
</@s.FacetedSearch>
 
And it returns the name of the fact as expected - so I know the @fb. stuff is there and is working.
 
From what I can gather from the rest of the documentation - I should just be able to pass into the Multicategories macro the name of the facet as a variable - and it should then almost cascade down to the other macros - the top macro generating the variables and calling the next macros and so on.
 
So something like this should do something?
 
<@s.FacetedSearch>
<@fb.MultiFacet name="section">
<h2>Test FACETS CODE</h2>${fb.facet}
<@fb.MultiCategories facet="section"/> 
    </@fb.MultiFacet>
</@s.FacetedSearch>

 

But again I just end up with the same error.

 

Expected hash. facet evaluated instead to freemarker.template.SimpleScalar on line 408, column 12 in web/templates/modernui/funnelback.ftl.

 

It looks like I should be passing through the variable in a different format?

 

I am using a GScope facet - could this be an issue?

 

Again - any help appreciated.

 

Thanks

Hi,

 

I gave up in the end.

 

As I'm really using gscopes - I added my own checkboxes and a bit of javascript to combine the checkbox values into one variable, append the correct polish expression at the end and submit this through a hidden field.

 

Works fine for now.

 

Would be nice if the documentation on the MultiCategories tags contained an explanation of how they are used in practice - maybe a demo block to add to the simple.ftl or something. 

I never quite worked out if I was entering the right variables in the right order or the right tags in the right order.

After 3 days of stumbling in the dark I'd had enough :)
