Append Map
I have a list of accoundIds and from this i want to find the fullname of the users.
i.e. inputing:
<list>
<s>accountId of user1</s>
<s>accountId of user2</s>
<s>accountId of user3</s>
</list>
Basically, i have a while loop that loops through the list of user id and find the user fullname using:
<invoke name='getAttribute'>
<invoke name='getObject'>
<ref>:display.session</ref>
<s>User</s>
<ref>nameIdx</ref>
</invoke>
<s>fullname</s>
</invoke>
where nameIdx is the accoundId
As i'm inputing a list of accoundid, so i need to a way to append a hash map.
The result that i'm aiming for are:
<map>
<s>fullname of user1</s>
<s>accountId of user1</s>
<s>fullname of user2</s>
<s>accountId of user2</s>
<s>fullname of user3</s>
<s>accountId of user3</s>
</map>
How can this be done?

R_L123,
You can iterate over your list using <dolist> in XPRESS, and for each entry maybe call the put method on a predefined java.util.Map object. But wouldnt it be easier to use a nested list object? Something like:
<defvar name="userMap">
<list/>
</defvar>
<dolist name='entry'>
<!-- your list here; eg, <ref>targetUsers</ref> -->
<block>
<defvar name='tmp'>
<invoke name='getObject'>
<ref>:display.session</ref>
<s>User</s>
<ref>entry</ref>
</invoke>
</defvar>
<append name='userMap'>
<array>
<invoke name='getAttribute'>
<ref>tmp</ref>
<s>fullname</s>
</invoke>
<ref>entry</ref>
</array>
</append>
</block>
</dolist>
Which would give you a nested list structure in userMap such as
<list>
<list>
<s>fullname of user1</s>
<s>accountId of user1</s>
</list>
<list>
<s>fullname of user2</s>
<s>accountId of user2</s>
</list>
<list>
<s>fullname of user3</s>
<s>accountId of user3</s>
</list>
</list>
And you could then refer to each user's fullname as index position 0 in the list, accountId as index position 1.
Alternatively you could concatenate both values in a string using some delimiter, and the <split> on that delimiter later.
I confess I havent run the code above but it ought to work...

Thank you for your reply and i'll soon try what you've suggested.
The reason that i am trying to construct a hash map is because i plan to present the user a 'select' list. The user will see a list of 'fullname'.
Once a particular option on the 'select' list has been selected and the submit button is pressed, i can then use the correspondin accountId to retrieve the selected user details.
