Hello Dojo,
I am trying to initialize 8 session variables on a Visual Overview page using Param placeholders. I have noticed that it does not work in the InitVar shape field so I am currently using the Execute field to set them. Now the parameter data that I am trying to set to these variables may not exist, and it seems when one of these placeholders do not resolve, then none of them do. Is there a way to prevent that? To not set that variable if nothing was found? Or is there a way to individually set the variables on initialization to prevent the failure of one to cause the others to fail?
Hi Gabriel,
You're looking for the AllowEmptyDynamicValues option which drops the requirement of resolving all placeholders before returning the complete resolved value of the shape data.
Note that the InitVar can't contain asynchronous placeholders since that would block opening the page. The current value of all placeholders is used instead and thus the [param:] placeholder will resolve to an empty string.
