I Get [object Promise] from handlebars helper, when i use childTemplate.call()

Since a few days i play around with jsReport to see if we could use it. And I am seriously stoked about it.
It could become a serious competitor for jasperreports for us.

I want to pass the content (innerhtml) of the whole handlebar to a child template and use it there. Only I don't have a working idea how to make this work.

Okay, I found the solution myself.

function notificationTemplate(name, title, color, opts) {
    return childTemplate.call({
            ...this,
            // add extra param
            data: {
                title, 
                color, 
                innerhtml: (typeof opts.fn == 'function') ? opts.fn(this) : 
                           (typeof opts.inverse == 'function') ? opts.inverse(this) : 
                           null
                },
        }, {
            name, 
            recipe: "html",
            engine: "handlebars",
    }, opts)
}

Only I have no idea what the opts.fn(this) or opts.inverse(this) is supposed to be.
But it works.

I' m glad you like what we do.

The opts.fn evaluate handlebars inside the block helper and returns a string. The opts.inverse does the same, but for the block you put into the {{else}} section.

Your solution looks good, you can even go just with
innerhtml: opts.fn(this)
