redirect to some url from workflow task ??

how do you redirect to another website from a workflow task. On click of the task, all that it will do is open another browser and redirect to some URL.

Is this possible? any code will be helpful.

You could attach a file with a meta redirect in it. The user would need to "start task" then select that file from the file list. That would open a new browser window. If that file redirected them to a new page - wow - there you go. Other than that I'm stumped.

Or else,
1) You could have a small JavaScript code within the template_script tag in wft file that would have window.open function with the URL you want it to open. Something like this:
<template_script><![CDATA[
my($brow) = "
<script>
var nwin = window.open('Your URL here', '_NEW');
</script>
";
print $brow;
]]></template_script>

2) One other way would be to have a CGI task and the CGI script should use either HTTP calls or maybe a javascript call. Remember this CGI task would use the same browser in whihc the workflow will run. So, use it only incase it is OK for you to have the same window in use for other task.

Hope this helps.

I tried creating following user task----
New instance of browser is immediately created when the workflow gets initiated..
I want this url to open when user clicks on Preview link as in
<successorset description="Preview">
<succ v="AuthPreview"/>
</successorset>

=======================
user task code is::

<usertask
name="AuthPreview"
owner="__TAG__('iw_user');"
description="Deploy submitted files."
>
<areavpath v="__INSERT__($areavpath);"/>
<successors>
<successorset description="Preview Complete">
<succ v="Author_Work"/>
</successorset>
</successors>

<template_script><![CDATA[
my($brow) = "
<script>
var nwin = window.open('http://teamsite5.cummins.com', '_NEW');
</script>
";
print $brow;
]]></template_script>

<activation>
<pred v="Author_Work"/>
</activation>
</usertask>

Any solution ????
Thanks.

You cannot use a <template_script> element to solve this problem if you want the redirect to occur as part of the exection of a workflow. The template scripts are evaluated before a job is instantiated.

If you want to send the user to another site, you could use a CGI task with a redirect. But how do you decide when the task is done (i.e., when do you want the following tasks to be activated.) You will have no way of knowing when the user is "done" with the redirect target unless that page sends some kind of message back to TeamSite. Or you could transition the CGI task before the redirect.

The best solution depends upon your requirements.

The code that I've seen posted basically brings up a new browser window with the specified URL as soon as the job has been instantiated - and only for the person who instantiated the job - regardless of whether or not they own the first (or any) task. Somehow I don't think that is what you are looking for.

So let's take this back a peg or two ...

1) What are you trying to do?

2) Why are you trying to do it? (not that it's wrong to do so - just trying to get some background on the use-case / rationale behind why this is desired)

3) Why does a cgitask not work for you?
(note: the cgitask would probably end up having to either use frames or open up a new window - as you will need some aspec of the CGI program to send a callback to the workflow)

I actually want to have a preview in the workflow task operations. And then this preview will link to ATG URL which has all the presentation pages.
Thus when author/editor will click on preview item, it should open a URL of my atg application in new window.

I will appreciate if you can give any example code to get this done.

Thanks.

Adam Stoller

Are you using the Interwoven Turbo for ATG product?
If so - I believe someone more familiar with that product than I will have to assist. Basically I believe there are a series of proxies that need to be setup and possibly a deployment of data (?) and with that being done, I believe you should simply be able to click on the file link in the Task Details view and be able to get the preview you want.

I realize there's more than one "I believe" above - unfortunately I cannot provide more concrete answers as that's not my area of expertise.

No, I am not using Turbo.
It is as simple as redirecting to some hardcoded URL and passing the data category, data type and dcr name as parameters to it...
ATG will then fetch appropriate data from the database and display the contents...
I need help in getting this done...

Adam Stoller

If you're not using turbo - and there isn't a proxy that can be used to turn the clicked on link of the file within the task into a URL request to ATG then I am pretty sure that your only choice is a cgitask with a wrapper script that does all the manipulations you want and then opens up the ATG-based URL.

I see 3 possible solutions:

cgitask script that brings up a framed CGI window - in which one frame has buttons for things like "Done" that can make a callback to the workflow engine, and the other frame is puplulated with the data from the ATG-URL

cgitask script that brings up the buttons in one window and then another window is launched for the desired ATG-URL

cgitask script comes up, sends a callback to the workflow letting it transition to the next step - and then redirects the current browser window to the ATG-URL.

The last option is probably undesireable as I'm assuming there's more than one possible transition you'd like to take after seeing this rendered page (yes?)

Perhaps you can post an attached workflow / state-transition diagram to help provide context for what you want to do?

avdhut,

As ghoti suggested, you could have a cgitask for this purpose. I have done similar thing in past and it works. With the cgitask ofcourse you will have your custom CGI that resides in httpd/iw-bin of your TeamSite home.
This CGI should:
1. Perform your validation and environment setting.
2. Either straightaway redirect to the custom URL using print "Location: $url \n\n"; (this incase you want to straightaway redirect to this new URL.)
3. If you want to provide user with the feature of button clicking for confirmation then you can use form action method. This way you could call the same CGI upon hitting the Submit button and that should send some hidden parameters for checking. These hidden parameters can be part of your query string for URL.

Remember to have a task callback for task transition in your workflow.
Hope this hleps.

I have created the following cgi file and called it like
<cgitask
name="AuthPreview"
immediate="t"
owner="__TAG__('iw_user');"
description="Deploy submitted files."
>
<areavpath v="__INSERT__($areavpath);"/>
<successors>
<successorset description="Preview Complete">
<succ v="Author_Work"/>
</successorset>
</successors>
<command v="preview.cgi" />
<activation>
<pred v="Author_Work"/>
</activation>
</cgitask>

when author clicks on the preview then he will move to the above cgitask.
<successorset description="Preview">
<succ v="AuthPreview"/>
</successorset>

and then this task is invoking the cgi.
the cgi file is placed in my home folder on solaris and a softlink exists in the <iw-home>\httpd\iw-bin folder.

when author clicks on preview new browser is opened and is redirected to
http://web405.cummins.com/iw-bin/iw_cgi_wrapper.cgi/preview.cgi?task%5Fid=1671&taskID=1671&session=52616e646f6d49567e29dc0938f1fe05c2512281cac4e673891d02379fd10c5d2534b7791eb79fe56b0a273433a3c9e4&area%5Fpath=.......

and the page displayed shows
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

can you please let me know what may have gone wrong ???

cgi code
===================
#!../../iw-perl/bin/iwperl

use TeamSite::Config;
use TeamSite::CGI_lite;
use TeamSite::WFtask;

$|=1;

my $iwhome = TeamSite::Config::iwgethome();
my ($cgi,$iwhome) = @_;

Content-type: text/html

<html>
<body bgcolor="#C0C0C0">
hello
</body>
</html>

my $callback = "$iwhome/bin/iwcallback $ARGV[1] 0";
$debug .= "callback = $callback " . "\n";
$debug .= `$callback`;

END

This doesn't look like a valid Perl script to me.

Always run "iwperl -c preview.cgi" on any Perl scripts. It will flag simple syntax errors like the ones I see in your script.

Looks like you are missing at least one "print <<END;".

Hope this helps.

Thanks.
I got some basic workflow working...
My concern now is how can I call the iwcallback from the cgi and restore the my workflow task....and then I can redirect to required URL...
I want this to be done without involving the authors..I don't want the users to click on any button for the workflow to proceed further.

Also - the script was written as a command-line script - expecting arguments to be passed in on the command line, instead of as a CGI script which parses PUT/GET/QUERY_STRING data.

See Workflow Tutorial - In there, amongst other things, you'll see bolierplate examples for cgitask script.

I'd encourage you to go through training (perl, workflow) - take a look at the offerings on the Education page on our Internet site for more details.

finally...its working
here is the code

=============================
#!../../iw-perl/bin/iwperl
#-----------------------------------------------------------------------------
# File Content Author / Editor Preview
#
# Author Avdhut Nate <cn561@cummins.com>
#
#-----------------------------------------------------------------------------

use TeamSite::CGI_lite;
use TeamSite::WFtask;
use TeamSite::WFworkflow;

$|=1;

$cgi = TeamSite::CGI_lite->new();
$cgi->parse_data();

$session = $cgi->{form}{'session'};
$task_id = $cgi->{form}{'task_id'};

my($task) = TeamSite::WFtask->new($task_id);
$task->CallBack(0, "Preview Complete");
print<<"END";

<html>
<HEAD>
<SCRIPT LANGUAGE='JavaScript1.2'>
opener.top.Ctl.pw_refresh();
</SCRIPT>
</HEAD>

<body bgcolor='white'>
END

$iwhome = `iwgethome`;

print "<font size='4'>Please wait while you are redirected to Circuit Authoring web application...</font>";
print "<SCRIPT LANGUAGE='JavaScript1.2'> top.location='http://circuitauth-test.cummins.com' </SCRIPT>";
print<<"END";

</body>
</html>

END

This is something like what I am trying to do. I would like to pop-up a window after the completion of thier task that alerts them of something. How would I do this?

If an "immediate" cgitask owned by user A is a successor to a usertask owned by user A, then the cgitask will open in a new browser window after the usertask is transitioned.

Hope this helps.
