page flow question

[Cyrus Serrano]

hi, i have two page flows is it possible to jump from one page flow to another page flow. And is it correct that the variables will be shared across the page flows. thanks again

Per my understanding, page flow is a bunch of related pages and actions for a certain business logic.

I am wondering why you have the requirement of jumping from one page flow to another. Or you mean communication?

Thanks

hi lin, the application was divided into page flows, meaning common(name) scripts were grouped together. So for example in Flow # 1 page A will jump to Flow # 2 page D. something like that.

But i get your point on application design that one page flow for a certain business logic. thanks

Any idea on how to attain my first question.

thanks again

[Cyrus Serrano]

any one has an idea if this is possible.. thanks

I wouldn't use globalApp for much of anything really. Try using request attributes (or parameters for non sensitive info) to pass data between flows.

    
 
public class Flow1 {

/**
 *@jpf:action
 *@jpf:forward name="success" path="/flows/package/Flow2/fromFlow1.do"
 */
protected Forward goToFlow2( MyForm formData ) {

getRequest().setAttribute("data", formData.getField());
return new Forward("success");
}
}
 
public class Flow2 {

/**
 *@jpf:action
 *@jpf:forward name="success" path="index.jsp"
 */
protected Forward fromFlow1() {

Object data = getRequest().getAttribute("data");
 
// do something with data
 
return new Forward("success");
}
}

hi kevin

thanks for that info. i didn't know that..

can i use session variables instead?

all thorough out the web application that variable is to be accessed much like a login information of a user like password and username which will be accessed anytime or anywhere of the web application.

i tried it, but it prompts an error.. it says about something about binding..

What is the error your getting? Please paste

I wouldn't use session variables for communicating between page flows.

i was able to make it work now.

previous code

<netui:textbox datasource={pageFlow.globalApp.sessionVar.Input1}/>

into

<netui:textbox datasource={globalApp.sessionVar.Input1}/>

by removing the pageFlow keyword, it worked fine now.

Additional question, is it a good design to jump from one page flow to another page flow and not starting on the begin action, but rather jumping to a jsp.

@Kevin,

what would you recommend to use rather than session variables. thanks.

Also this was the previous error..

Caught exception when evaluating expression "{pageFlow.globalApp.callVars.inputA}" with available binding contexts [actionForm, pageFlow, globalApp, request, session, appication, pageContext, bundle, container, url, pageInput]. Root cause: knex.scripting.javascript.EvaluatorException: The undefined value has no properties.
