SizeOfPropertyList in an HTML fragment
Hi,
I',m working on a Pega application that has been upgraded several times from Pega 4.x to Pega 7.2.2. I need to access an Amount property on an Occurrence page, but Occurrence is sometimes a single page and other times a page list.
I've tried this:
<pega:when java="pega_rules_utilities.SizeOfPropertyList(.Occurrence)<=0;">{.Occurrence.Amount}</pega:when>
<pega:when java="pega_rules_utilities.SizeOfPropertyList(.Occurrence)>0;">{.Occurrence(1).Amount}</pega:when>
And this:
<pega:when test="@(Pega-RULES:Utilities)SizeOfPropertyList(.Occurrence)<=0">{.Occurrence.Amount}</pega:when>
<pega:when test="@(Pega-RULES:Utilities)SizeOfPropertyList(.Occurrence)>0">{.Occurrence(1).Amount}</pega:when>
Neither one works. I know I'm close, but can anyone point me in the right direction?
Clearly fixing the clipboard to have the Occurance be a Page List (in all instances) would be preferred, but I'm afraid I'll break something else in the process.
Thanks in advance,
Kirk

Thanks for your reply SantanuBhattacherje. I'm was trying to use the function directly in tags in an HTML Fragment rule.
I've figured out a solution. No matter how I tried using the SizeOfPropertyList function within a tag, it always threw an error when the page list did not exist and was checking for Occurrence(1). I have created a separate block of Java code to check for the existence of the first page in the page list: Occurrence(1) and wrapped it in a try/catch block [And BTW attempting to insert a try/catch block directly within the tag does not work.] :
<%
Boolean isOccurrencePageList = null;
Object occurrence = null;
try {
occurrence = tools.getProperty(".Occurrence(1)");
isOccurrencePageList = true;
}
catch (Exception e) {
isOccurrencePageList = false;
}
%>
I then use the isOccurrencePageList variable later in the HTML fragment:
<pega:when java='<%= !isOccurrencePageList %>' ><pega:reference name="tmpWorkPage.Occurrence.Amount"/></pega:when>
<pega:when java='<%= isOccurrencePageList %>' ><%=tools.getProperty(".Occurrence(1).Amount")%></pega:when>
Voila. I have a workable solution.

Hello
You said that you need to access an Amount property on an Occurrence page, can you please let me know how you are trying to access it ? Via activity , data transform or some other way ?
