Array as a parameter by "callAS"-method (JavaScript/ActionScript Bridge)

What is in the array? I believe that only generic parameters can passed.

What is received on the ActionScript side?

I want to update the dataProvider of mx:List via another RMA in my pdf. So the array looks like:

array = [{label: "label1", data: 0}. {label_ "label2":, data: 1}....]

I realized the tutorial of Joel Garcia (http://pdfdevjunkie.host.adobe.com/RMA3_RMA2RMA.shtml) and changed his content to mine.

So i made a String in ActionScript side, which i tunnel with the "eval" function. So the string seems to be "defined" in Javascript.

My functions work with string and integer as parameter in my callAS-method. But not with an array :(

On the ActionScript side, the function, which i call does not accept my parameter and does not fill out this path.

So what is received on the ActionScript side? Is the input argument null? is it an array of null parameters? is the function called at all?

Have you tried passing an array of simple integers or strings? It may be that the problem is not the array, but the objects in the array.

JavaScript does not have an "associative array" - they're objects, not members of the Array class, so the declared type for your function doesn't match. Unless it does, the ExternalInterface layer will not call the function.

Maybe i can try to call the array by a String? So on Actionscript side, i have to kill the quotationmarks through a function? These "sentences" i can set into an array...Is this possible?

Many thanks for your fast answers! You made my day better cause i became desperate last day :/

No, you can pass the data as an "array" just fine, but just declare your variable as an "Object" in AS3:


in AS3...

function receiveSomething(o:Object):void {
// o[0].thing == sandwich, etc.
}
ExternalInterface.addCallback("sendObject",receiveSomething);



In AcroJS...

var myObj = [{label:"one",thing:"sandwich"},{label:"two",thing:"cake"}];
rma.callAS("sendObject", myObj); // returns undefined

just like this, i coded it the last hour...it works fine :) :) bad luck, that acrobat don´t save the "change" of the List-Objects for further times. now i`ll try to save it in an attached xml file, so that the List within the RMA can get his information from the xml file. it should be like an editor...

thank you

It would have helped if you'd explain what you're trying to do at the start. Storing stateful information between sessions is a whole different topic, and requires very specific techniques. You certainly can't use an RMA resource file as a read/write buffer, nor can a SWF annotation open file attachments made at the document level.

Using this idea ( http://pdfdevjunkie.host.adobe.com/RMA4_exportData.shtml )for "printing" data of my List in an xml file...Saving it (the xml file)...Another pdf-version should use this XML-File as his Information-Getter...
Should work...Or not?
