dialog.isLoggedIn issue

[JPMPA]

I have setup Alpha Security. Now I have a login page, etc pointing to the SQL server tables [all these were automatically created by Alpha when I set the security to SQL Database, etc.] Also added some test accounts (all in administrator group for now.)
On successful login I have specified to go to another page say my_page.a5w. Also added this page to the page security with the login required option.
With incorrect login, as expected I get the error message.
When I successfully login, I get redirected to that above page.
So far so good.
The problem is that when I get redirected to that above page, it is not able to access dialog.isLoggedIn value on that page.
The error message is
"dialog.isLoggedIn = undefined" or "Error: dialog is not defined"
What could be the reason? Thanks.

Re: dialog.isLoggedIn issue

Have u set security for components?

Re: dialog.isLoggedIn issue

For components I have set no security [Always allowed for my current component] as the wrapper my_page.a5w page has the security set. Just to test after your post - I tried both ways [the Components security for this component off and on], published and restarted the app server. No difference. It is still failing at dialog.isLoggedIn.

if (dialog.isLoggedIn == true)
{alert("The value is true"); // plus other custom logic}
else
{alert("The value is false"); // plus other custom logic}

Re: dialog.isLoggedIn issue

How do I find out within an UX component if I am (or user is) logged on. I have a UX that we need to access using both logged in and when not logged in mode. I need to hide some functionally and use some type of indicator in javascript that I am logged in or not. Since I am not able to use dialog.isLoggedIn - is there any other variable or function available? Kindly let me know, Thanks.

Any help? I appreciate your time. Thanks!

Re: dialog.isLoggedIn issue

Have you tried using {dialog.object}.IsLoggedIn The property is associated with the dialog object the pointer to which is accessed by the {dialog.object} syntax.

Re: dialog.isLoggedIn issue

I do not have version 12 so I do not even know about {dialog.object}.isLogggedIn function.
the problem I see is in logic, that is what I am pointing out. the methods, as I mentioned are foreign to me.

The problem is that when I get redirected to that above page, it is not able to access dialog.isLoggedIn value on that page.

you said you have a login and on successful login you will be directed to another page and then you are trying to find out about the {dialog.object}. isLoggedIn. naturally you will get error since the dialog does not exist any more and all things with the dialog are gone. possible alternative would be to set the a variable loggedin and pass that variable to the new page
or
stay in the same dialog and do what ever you are doing in that page and you will have access to that value since the dialog is still open.

Re: dialog.isLoggedIn issue

Here's what you need to do to accomplish what you're asking: in the Server Side events of each UX component that you need to have special functionality visible for logged in users add the following code in both the OnDialogInitialize and OnDialogSynchronize events. You have to add it to both because if you cache the component then the first time it is called the OnDialogInitialize fires but on subsequent calls the OnDialogSynchronize fires instead.

dim un as c
un = a5ws_getcurrentuser()
'If a userID is returned then the user is logged in
'Set a flag in the dialog State that can be accessed by client side javascript
if un <> "" then	
	session.IsLoggedIn = 1
else
	session.IsLoggedIn = 0
end if

Now on the client side you first need to publish the session variable so it is visible to javascript and client side events. Wrap any control or controls on your component that you want to hide in Containers and then on the container click the event handler for Client Side Show/Hide expression. In the dialog box that pops up click the link on the lower right side to Publish Session Variables. Enter the variable SESSION.ISLOGGEDIN in all caps (case is important) and then click Okay. Now in any of your Show/Hide events for your containers just type in SESSION.ISLOGGEDIN = 1. This will show the controls that are wrapped in the containers only when the component is being used by a logged in user and hide them from all others. When you close the dialog the first time you'll be reminded that you've referenced a session variable and that you must publish it to make it visible. Since you've already done this you can ignore the message.

This same technique is useful as a substitute for the Server Side security show/hide options which can really take their toll on the time it takes to open a component. Instead I create Session variable flags for the groups that a user belongs to and then use those flags to do client side show/hide events which eliminates having to recalculate the UX component every time it opens based on security.

Re: dialog.isLoggedIn issue

if you choose to do the same without a session variable when dialog initializes assign a field value( hidden field) and all the controls can be in one frame and frame is hidden if that field is empty.

Re: dialog.isLoggedIn issue

The problem I ran into with the hidden field method (which I tried initially) is that the dialog will only initialize them in the OnDialogInitialize event. If the status changes and you reopen a cached dialog the hidden fields do not refresh even if you add the same code to the OnDialogSynchronize event so the only way I've found to consistently refresh is the method I described using session variable assignments. The other nice thing about session variable assignments is you don't end up cluttering your form designer with hidden fields so you can focus on the actual fields on the form.

Brad/Gandhi, Thank you so much. I will try now.

Re: dialog.isLoggedIn issue

Thanks! Server side a5ws_getcurrentuser() will be helpful in my logic. I will set my required values using that and/or may be update some client side variable using that. Appreciate your help!

function serverside_78c653353224bc05947feca2y77d as c (e as p)
serverside_78c653353224bc05947feca2y77d = "alert(' Current User is: " + a5ws_getcurrentuser() + "');"
end function
