Incident state management or State transitions or State model

[Shantharao]

Hello All,

I want to manage incident state transition flow as below

We have 6 out-of-box choices for incident form as below

/*
state 1 is "New"
state 2 is "In Progress"
state 3 is "On Hold"
state 6 is "Resolved"
state 7 is "Closed"
state 8 is "Canceled"
*/

OnChnage of state field to "New" I have to show below 4 choices as below

"In Progress"
"On Hold"
"Resolved"
"Canceled"

OnChnage of state field to "In Progress" I have to show below 3 choices as below

"On Hold"
"Resolved"
"Canceled"

OnChnage of state field to "On Hold" I have to show below 1 choices as below

"In Progress"

OnChnage of state field to "Resolved" I have to show below 4 choices as below

"In Progress"

"Closed"

I created one onChnage client script onChange of "state" filed, I am adding options to same state filed but I am getting infinite loop, not getting proper results

Please suggest me the best practice for implementation, please find the sample script

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
/*
state 1 is "New"
state 2 is "In Progress"
state 3 is "On Hold"
state 6 is "Resolved"
state 8 is "Canceled"
state 7 is "Closed"
*/
// var incState = g_form.getValue("state");

if(newValue == "1"){
g_form.clearOptions("state");
g_form.addOption("state","2","In Progress");
g_form.addOption("state","3","On Hold");
g_form.addOption("state","6","Resolved");
g_form.addOption("state","8","Canceled");
g_form.removeOption("state","7");
alert(newValue);

}
if(newValue == "2"){
g_form.clearOptions("state");
g_form.addOption("state","3","On Hold");
g_form.addOption("state","6","Resolved");
g_form.addOption("state","8","Canceled");
g_form.removeOption("state","1");
 g_form.removeOption("state","7");
 alert(newValue);

}
if(newValue == "3"){
g_form.clearOptions("state");
g_form.addOption("state","2","In Progress");
 g_form.removeOption("state","1");
 g_form.removeOption("state","3");
 g_form.removeOption("state","6");
g_form.removeOption("state","7");
g_form.removeOption("state","8");
alert(newValue);

}
if(newValue == "6"){
g_form.clearOptions("state");
g_form.addOption("state","2","In Progress");
g_form.addOption("state","7","Closed");
 g_form.removeOption("state","1");
g_form.removeOption("state","3");
g_form.removeOption("state","6");
g_form.removeOption("state","8");
alert(newValue);

}
}

Could you do it onLoad instead?  That way it only loads once on the form load.  Once you save the state to the new value it would run once again to get available choices.

I found an excellent feature from Madrid release called State Management->State Model

With out writing any coding we can handle the state transitions in smooth manner

Please find the screen shots for reference 

1.Created Incident Flow state model

2.Created Incident Transitions 

3.In Progress State Transition

We can change the state from New or On Hold or Resolved to In Progress, please find the screen shot

4.On Hold state Transition

We can change the state to "On Hold" from state "New" or "In Progress", find the screen shot
