check for empty textValue using getStructuredDataNode

We have a staff foreach where we output 6 required fields and 1 optional. All our required fields come in fine but as soon as 1 optional field is populated, the format populates all the other optional fields with that one value... I obviously only want the field to show if it has a value but it seems the system thinks it always has a value.

 #set ($creds = $asset.getStructuredDataNode("credentials").textValue)
#if($creds.value !=""), $creds#end

^^ this code shows all the all the same values as the only value set

 #if($asset.getStructuredDataNode("credentials").textValue !=""), $asset.getStructuredDataNode("credentials").textValue#end

^^ this code shows the value of the one populated field and then " , $asset.getStructuredDataNode("credentials").textValue " for the rest...

How do I check if the credentials field is populated?

Thanks in advance!

   Just tried:

   #if(!$_PropertyTool.isNull($creds))#if($creds.isText()), $creds.textValue#end#end
   

   this code shows the value of the one populated field and then " , $creds.textValue " for the rest...

   ok then... this seems to work:

   #if(!$_PropertyTool.isNull($asset.getStructuredDataNode("credentials").textValue)), $creds.trim()#end##

   Hi Nando,

   You got it, I am glad to see you were able to find the solution.

   When the node has no value the textValue property will return null. This is why you were seeing the literal code being output instead of the value (or nothing), because Velocity will simply "dump" the code if you try to output null (since it's technically a Null Pointer Error).

   I'm going to go ahead and close this discussion, please feel free to comment or reply to re-open if you have any additional questions.

   Have a great day!
