Illusion in Standard Interactivity

Whenever I am asked to work on siebel standard interactivity it feels like harry potter stranded in those wild mazes. But i can tell you if you play in Java/HTML you can really unearth hidden gems in SI application. Recenty while working on Siebel eSales portal we were asked to implement typical requirement to control button's visibility conditionally. 

For the Open status button should be visible on list applet and for other status values it should be hidden. Once again "WebApplet_ShowControl" server event is critical to its implementation as other browser events of applet are not supported in SI architecture. The idea is to modify the HTML generated at run time to achieve conditional visibility. Below steps are required for ultimate illusion.


1 - In the HTML attribute of the Button Control which we want to make conditionally visible add below property
style='visibility:hidden'
By default button will be hidden and we will only make it visible when status is Open.


2 - Below piece of script is required at "WebApplet_ShowControl" event on the server side of applet.
if ((ControlName == "Test") && (Property == "FormattedHtml"))
 {
var a = HTML.indexOf("visibility");
var b = HTML.indexOf("'",a+1);
if ((a > -1) && (b > -1))
{
var sr = this.BusComp().GetFieldValue("Status");
if(sr=="Open")
var t = "visibility:visible'";
else
var t = "visibility:hidden'";

var HTML2 = HTML.substr(0,a) + t + HTML.substr(b+1);
HTML = HTML2; // Re-Generating HTMLs
  }
 }
Here we are just checking the status value and modifying the generated HTML at run time to make button dynamically visible.

If in first attempt it doesn't work don't get mad at me just clear the cache and watch out for magic. Bet me you will feel like wathcing The Prestige again.

Happy Summers!!
