Answered NewsPublisher: getReqParam and parentid

This last revision fixed the blank page issue but the picker is empty.

Make sure the resource you set as the parent has children that are published and are folders. I just tested it in NewsPublisher and it's working fine for me:

Hmmm, I'm definitely missing something.

For me, id 2 is the parent that contains everything I need returned. Both it and all the child containers are indeed published.

Try putting a & in front of the parent property.

Someone must have it in for me ... the picker is still empty.

I'll have to add this to the list of things to revisit.

Thanks, Bob.

Hi Bob,

I'm struggling with the parentid param here as well. I would like to dynamically set the parentid based on a url param and am using the fastField extra to grab a value from the URL. Simple enough. I have the NewsPublisher snippet call in a chunk (so that the RTE doesn't bung things up). The chunk with the NewsPublisher call looks like this:



Where +caseId is passed as an argument of the chunk like so:

The page outputs the case id at the top, e.g. ("Case ID: 34") but the new resource doesn't appear under the resource with ID 34.

Do I understand correctly from another post that NewsPublisher requires a static int value for parentid? Shouldn't the parser parse my [[!+caseId]] placeholder? Am I missing something?

This post states the same issue, but I don't understand the op's solution.

Try this in the property:



Calling the placeholder uncached here delays its processing, so it's probably not available when the NP tag is parsed. Since you're setting it earlier with an uncached call, it should be a fresh value. You do have the code that sets the placeholder above the NP tag, right?

It's fine if the ID is in a string. All snippet properties come in as strings.

Bob,

Calling the placeholder cached as you suggested worked like a charm. I got a little slap-happy with the uncached calls- never a good idea without good reason! Thanks for your help, and for the quick response, and moreover:

Thanks for putting together the NewsPublisher extra- it's saved me hours of development time.

 &parentid=`[[+caseId]]`

I'm glad that worked. Thanks for reporting back.
