Hi Chloe,

Please have a look at the following KB article: http://kb.k2workflow.com/Articles/KB000008.aspx

I got the following error when using the code mentionned in the knowledge base:
<script language="javascript" type="text/javascript">
    var bW3Compliant = (document.getElementById) ? 1 : 0;
if (bW3Compliant) {
document.Form2.K2Submit.onclick = K2Button1_onclick;
    }
function K2Button1_onclick()
     // fires prior to server posting.
{
    return (confirm("Are you sure you would like to start this process?")) ? true : false;
}
</script>

Server Error in '/Film Elimination' Application.

Have a look in K2.net Service Manager under Error Profiles. You should see more information as to the reason why the process instance is in error state.

Hi there,

I'm now getting a different error. The process status is set to error, but when I got into the service manager I can't find any explanation for the error under error profiles. Any idea why the error wouldn't show here, or how I can find out why the error has occurred?

Thanks,

Chloe

Make sure that you have no filters specified on the Error Profile in K2.net Service Manager. You can also add a new Error Profile with the default configuration; this will insure that all errors are displayed.

Hi there,

I'm just returning to this issue after ignoring it for while! I have required field validators on my asp.net page, when I do Page.IsValid in the workflow button event, the workflow is started regardless if problems are encountered. I tried the javascript function as recommended, and it works fine, displaying a message box. I'm not sure how to build in here a way of checking my required fields though. What I really want it to do is use my required field validators to check the textboxes. My javascript isn't great, but is there a way of doing this? Or if not a way in javascript that I can check that the required fields are present?

Thanks in advance!

Chloe

Your best bet is using the java script as explained in http://kb.k2workflow.com/Articles/KB000008.aspx

Hi,

To test for a required field server side: Add a required field validator to the form, link it to the textbox you would like to test against.

Set the K2 button's CausesValidation property to True...

When you click the button, the setting will force the required field validator to fire before the code of the button click event - thus you don't need to test for anything in code. If a field is empty the validator's error message text will be displayed - the process will not start...

You can also add a summary validator control to display the errors of all validators in one list.

Note: The validator must be visible - if it's visible property is set to False, it will not fire!

Hope this helps,
Tersia
