BIRT Viewer isdisplayXXXX Parameters

The BIRT Viewer application generate these __isdisplay parameters and one for each customized parameter created in the report RPTDesign file.

What is the purpose of these parameters? How it is used internally?

Thank you for your feedback.

Vicky,

For list boxes and combo boxes you can set a value and a display value for the parameter. The Display Text is shown to the end user. To retrieve the value of these in an expression do this

//Birt 2.5
params["NewParameter1"].displayText
or
params["NewParameter1"].value

the isdisplay setting allows you to change the display text with a url parameter.
eg add this to the url
&__isdisplay__NewParameter1=newdisplaytext
