Using dynamic context attributes with flashisland

Question

I recently started looking at flashislands.
Going through the SDN tutorials on this topic, I noticed that the declarations of GACDATASOURCE and GACPROPERTY properties inside web dynpro and their counterpart variables inside flex are a bit static (all naming and binding is done at design time).
So I'm asking if there's a way inside flex to dynamically capture the values of the attributes of a web dynpro context node that is bound to an ArrayCollection variable inside flex without knowing the names and the amount of the attributes of the context node?
Here's my situation:
I have a context node (REPORT_DATA) inside web dynpro that at design time has no attributes.
The attributes and their names are created dynamically at runtime.
It is even so, that over time the amount of attributes may vary.
Inside the web dynpro, the contents of this context node (REPORT_DATA) are shown in a (dynamically built) table.
Besides using the table, I'm trying to show the same contents as a piechart and as a columnchart in a flashisland.
The ROOTUIELEMENTCONTAINER of the FlashIsland view in web dynpro only contains a GACDATASOURCE element at design time.
The 'dataSource' property of this GACDATASOURCE is bound to the context node REPORT_DATA.
The 'name' property of this GACDATASOURCE is bound to an ArrayCollection variable inside flex (named dataSource).
So much for the static part created at design time.
At runtime inside web dynpro the correct GACPROPERTY's are created, based on the - over time changing - amount and the names of the context node.
Suppose my REPORT_DATA context node at runtime starts with 3 attributes: ATTR1, ATTR2 and ATTR3
Also suppose the node contains 2 elements: [ {"1_1", "1_2", "1_3"} , {"2_1", "2_2", "2_3"} ]
The dataSource variable inside flex also contains 2 entries with 3 elements each.
The code to show the value of (for example) the first element of all entries inside the ArrayCollection variable would be:
+for each( var o:Object in dataSource) {
var s:String = o.ATTR1;
Alert.show( "the 1st value = " + s ); // 1_1 for the first entry, 1_2 for the second
}+
I can then use the myAC variable inside flex as dataprovider for various other objects.
This works fine.
But inside flex I can only capture the value of an attribute when I know its name at design time (like ATTR1 in the sample code above).
And that's not what I want.
Inside flex I want to capture the value of the context attributes dynamically in a (correctly typed) flex variable without knowing the names and the amount of the context attributes.
Is this possible?
Thanks in advance for - any - response.
Bart.

Hi again,
I tried the same thing by creating a dummy context node without any attributes, and adding all attributes at runtime using the add_attribute method. In that case too, it doesnt work. All the attributes are available in the dynamic attributes of the node element, but are not getting displayed.
Any help would be greatly appreciated. Thank you.
