Default Another way to read page number?

For many years we have used a different software for personalized images. That software creates the images and creates an appended data list, such that the name of each unique image is in a new field named "Field1", "Field2", "Field3", etc. I bring that appended data into a simple template that I use to keep an updated contact sheet. Each page consists of 8 picture and text frames using the rules below:

Text frame rule called label1:

HTML Code:
return (((FusionPro.Composition.currentPageNumber-1) * 8) + 1)
Graphic frame rule called graphic1:

HTML Code:
var pic = CreateResource(".//images//" + Field("Field" + Rule("label1")), "graphic", true)

return pic
Theses rules are duplicated 7 more times and customized for each position.

This works great. As I get more images, I duplicate as many pages as necessary, and it keeps bringing in the appropriate images and labels. Right now, I am up to 134 images.

Now we are using FP Expression. So I thought I could continue with a similar style by using this rule:

HTML Code:
var ResourceName = Rule("label1"); 
var Field1 = "First"; 

var myPI = Resource(ResourceName);
myPI.AddData(UntaggedRuleOrField(Field1) || " ");


return myPI;
and then name my FP Expression resources beginning at 135 to pick up where the other images ended.

This is not working, because the call to create the Expression images happens before composition, so it is not bringing the composition page number into the label rule calculation, thus resulting in not being able to find resource 0, resource -1, resource -2, etc.

Is there an alternative way to read the template body page number so it can be calculated up front?

Thanks

Sure, check the "Re-evaluate this rule for every graphic frame" box on the Rule Editor, and you can use the property FusionPro.Composition.currentPageNumber in the rule.

Though, instead of having to manually add pages to the template whenever there's a new resource, you could just repeat the record with a single page with one graphic and text frame on it, and use imposition to place an arbitrary number of those pages on each output sheet.

How To Ask Questions The Smart Way

The correct spellings are JavaScript, FusionPro, and MarcomCentral (each with two capital letters and no spaces). Acceptable abbreviations are JS, FP, and MC (or MCC). There is no "S" at the end of "Expression" or "Printable"! The name of the product is FusionPro, not "Fusion". "Java" is not is not the same as JavaScript.

Check out the JavaScript Guide and JavaScript Reference! FusionPro 8.0 and newer use JavaScript 1.7. Older versions use JavaScript 1.5.

return "KbwbTdsjqu!spdlt\"".replace(/./g,function(w){return String.fromCharCode(w.charCodeAt()-1)});

Thanks, Dan! I had forgotten to check the re-evaluate box on my FP Expression rules. I'll have to try the imposition method sometime.
