We can Iterate pxFlow Page Group property sequentially even it is subscript based
pxFlow is a page group property, but in Pega we can iterate thru for each embededpage either from an Activity or Data Transform, but it looks like HashTable and HasshMap in java and these are key/value pair lists we cannot iterate in Java.
However in Pega we can iterate pxFlow using for each embeded page even it is subscript based, how does it works, what is the internal mechanism inside? and it is not index based.

Hi Kavil,
You can check the Java code generated for such activity and Data Transform. There you will see how Pega is handling this loop internally for Page Group. Goto Activity > Action Button > View Java
Example code:
ClipboardProperty pz_2 = pzPrimPage
.getIfPresent(".pxFlow");
pageRef = pz_2;
}
if (pageRef != null) {
myPageList = pageRef.iterator();
while (myPageList.hasNext() && (pz_Status == true)) {
forEachCounter++;
tools.putParamValue("pyForEachCount", Integer
.toString(forEachCounter));
nextPage = (ClipboardProperty) myPageList.next();
thisStepPage = nextPage.getPageValue();
{
if (pz_Status == true && nextBlock.equals("")) {
pz_methodStatusUpdated = false;
pz_CurrentStepNum = "3";
if (oLog.isDebugEnabled()) {
oLog.debug("Running step 3_circum0");
}

Yes, you are correct that they use Map data structures which are unordered. However even in java we can iterate on them using Iterator and many other ways, only thing is that order is not guaranteed.
Same applies to pxFlows in Pega, we can iterate on them but order is not guaranteed.
Let us know if this helps :)
