Check Rows
Hello,
I want to that an action link only appear when the following condition is true
[[@Site.GetValuesForQuery('Employee', '<Where><Contains><FieldRef Name="Trainee" /><Value Type="Lookup">[[Title]]</Value></Contains></Where>', 'ID')]].length<2
This doesn't work if I have no entries in my list, so I get an error.
What can I do?
Kind regards
Nicole

Hi Nicole
Just made some tests for this case. For me it works without any errors even with empty lists. What error message did you get?
Good to know and to check: @Site.GetValuesForQuery function is looking for lists with this name in root site if you just use list's name instead of list's url.

I got the following error
If insert the Url like you say I got the following message
But the url exists. What is wrong?
Kind regards

Hi Nicole Geier
If the List Parents is not in the root site of your site collection you have to use the URL.
In your list URL example you missed the starting / ( forward slash).
This is probably the issue.

I have insert the URL starting with / ( forward slash), I have insert the complete list URL and it doesn't work.
I get always the error that "does not exist at site with URL".
It only recognize the list if I insert only the listname (in my case 'Parents)'.
My list is in this site collection but not in the root.
Sorry I have no idea why I don't work in this part of the action links (1.3.7.4)
Kind regards

Hi Nicole Geier
Could now reproduce the use case you asked for. You do it right when you just use the Listnames as first parameter.
It's true, the property length is not available when the Query List function returns no items.
Therefore you have to handle this case by checking first the returned result.
This is how this check looks like:
Switch to Function code and use this check with your query list configuration.
var items = [[@Web.GetValuesForQuery('Employee', '<Where></Where>', 'ID')]];
if(items) {
return items.length < 2;
}
return true;This returns true if there are no items returned. If items are returned it checks amount agains smaller than 2.
