Comala workflow remove value from parameter

[Marya Belanger]

In my workflow, I have a parameter that I'm adding labels to (every labeladded event) :

{trigger:labeladded}
    {set-metadata:Page Labels}
    @Page Labels@, "@label@"
    {set-metadata}
{trigger}

how can I remove a value on a labelremoved event?

{trigger:labelremoved}
    {set-metadata:Page Labels}
    @Page Labels@ - "@label@"
    {set-metadata}
{trigger}

Obviously not with a minus sign, but is there any way to do this?

Hello @Marya Belanger 

You can do this with the @labels@ value reference, 

{trigger:labeladded}
    {set-metadata:Page Labels}
    @labels@
    {set-metadata}
{trigger}
{trigger:labelremoved}
    {set-metadata:Page Labels}
    @labels@
    {set-metadata}
{trigger}

If you are looking to reference this metadata value in a page using the Comala Document Management {get-metadata} page macro, then you can simply specify this value reference in the macro config, e.g:
