If allTextFrames is a collection of text frames from a layer, why does the line below give me a null error?
I’m currently working around it by doing this line below so I can export PDFs via page range with the value in currentPage.
Can you please show us how you construct allTextFrames?
I can run this without error:
What is "a null error"?
var allTextFrames = new Array();
allTextFrames = myLayer.textFrames;
The alert shows me nulls.
I get a a "type error null is not an object" but I now realize that is later in the script.
I assume you mean .parentPage in the assignment line of your script.
In which case the alert shows me "[Page]" which is as it should be.
What version of InDesign?
Also, this construction:
var allTextFrames = new Array(); allTextFrames = myLayer.textFrames;
is both superfluous and unwise. You declare allTextFrames, initially assign it the value of the Array constructor, as if it were an array, and then you assign it to a collection.
In this case, simply
var allTextFrames = myLayer.textFrames;
would be sufficient.
What's the minimal document necessary to make your script fail?
Also, it would be nice to see an example that stands on its own.
This one depends on myLayer, so it's annoying for others to test.
A TextFrame is always located on a Spread but not necessarily on a Page. That's why tf.parentPage may be NULL.
To see what exactly happens use the following test:
alert( myLayer.textFrames.everyItem().parentPage.toSource() );
