TYPO3 Fluidcontent - load page via pagenum

In older projects (< TYPO3 7.6) I was using the following code to load a page with a pagenum:

ajax = PAGE
ajax {
    typeNum = 2008

    10 < styles.content.get
    10.stdWrap.innerWrap >

    config {
        disableAllHeaderCode = 1
        additionalHeaders = Content-type:application/json
        disablePrefixComment = 1
        xhtml_cleaning = 0
        admPanel = 0
        debug = 0
        no_cache = 1
    }
}

Now we're working with TYPO3 8.7 and Fluidcontent and when using this code, a blank page is being outputted, no content. I had a look into the Object-Browser and it seems that styles.content.get should still work.

I'm afraid it doesn't work anymore because of Fluidcontent and the different structure for backend layouts. Unfortunately, I could not find anything helpful on Google. Does anybody know how to use this (load page via pagenum) with Fluidcontent in TYPO3 8.7?

styles.content.get is defined very late with fluidcontent. so your copy might copy an up to then undefined/ empty definition.

• either use the reference operator =<,

• define it by your own:

.

styles.content.get = CONTENT
styles.content.get {
    table = tt_content
    select {
        orderBy = sorting
        where = colPos=0
    } 
}

• or use this immediately:

.

ajax {
    10 = CONTENT
    10 {
        table = tt_content
        select {
            orderBy = sorting
            where = colPos=0
        }
    } 
}
