Pass a variable to a content object containing a tx_news plugin - typo3

Question

This is very similar to my question Counter for mask elements in a TYPO3 column
I need to pass a variable (in my case, the value of cObj:parentRecordNumber which is the counter for the current item in it's column) to the template.
In the main page template:
<f:cObject typoscriptObjectPath="lib.content.pageteasers" />
In typoscript:
lib.content {
pageteasers < styles.content.get
pageteasers {
select {
where = colPos=2
max = 8
}
// this passes the variable elementCounter to the fluid template of the rendered mask content element:
renderObj.mask_teaser {
variables {
elementCounter = TEXT
elementCounter.value = {cObj:parentRecordNumber}
elementCounter.insertData = 1
}
}
// this should pass the same value to a rendered tx_news plugin:
variables {
elementCounter = TEXT
elementCounter.value = {cObj:parentRecordNumber}
elementCounter.insertData = 1
}
// it doesn't. what about these trial & error:
renderObj.list < .variables
renderObj.plugin.tx_news < .variables
renderObj.list.20.news_pi1 < .variables
renderObj.news_pi1 < .variables
// none of these seem to work either
}
}
And then in the rendered CE template (News/List.html)
<f:debug title="" inline="1">{_all}</f:debug>
I don't manage to see the above variable in here. What is the correct way to pass the variable from TS to the news fluid template?
PS Another try was using the Good Old Register
pageteasers < styles.content.get
pageteasers {
select {
where = colPos=2
max = 8
}
append = LOAD_REGISTER
append {
elementCounter = TEXT
elementCounter.value = {cObj:parentRecordNumber}
elementCounter.insertData = 1
}
}
And in the template:
{v:variable.register.get(name: 'elementCounter')}
but that is NULL

Your try via register could work. But you have to care, where you are doing what...
Registers
LOAD_REGISTER is of type string/stdWrap and not a cObject per definition. If you wanna use content based on a cObject, you can declare this via the stdWrap-property (as shown in the examples):
1 = LOAD_REGISTER
1.param.cObject = TEXT
1.param.cObject.stdWrap.data = GP:the_id
So, in your case it should like:
elementCounter.cObject = TEXT
elementCounter.cObject.data = cObj:parentRecordNumber
Appending at the right place
You are trying to use append directly as a property of pageteasers (which is a copy of styles.content.get which is of type CONTENT.
CONTENT does not have an append-property. In addition, you would put the register in front of the entire content, not the individual content elements.
=> It's needed as part of the renderObj, so it's rendered per CE.
The renderObj of CONTENT is of type CASE, which also has no stdWrap-properties directly. But it has a property stdWrap with stdWrap-properties...
Conclusion
So, you can end up with this snippet:
lib.content {
pageteasers {
renderObj {
stdWrap {
append = LOAD_REGISTER
append {
elementCounter.cObject = TEXT
elementCounter.cObject.data = cObj:parentRecordNumber
}
}
}
}
}
