Have you seen this error before? Did you find a solution? I was getting this javascript error on the click of a button that had a simple rule attached to it. Everytime I clicked the button, it produced this javascript error:

Null is null or not an object.

After some debugging, I noticed that the error was occuring in the "owsbrows.js". This file contained a line that was trying to load a value from the control that was clicked in the form. The control returned "null" and hence InfoPath generated this beautiful error message.

Reason?

The postback setting of the button was set to "Never".

Solution?

Set the postback setting of the button to "Always".

1. Right click the button.
2. Select "Button Properties".
3. Select "Browser forms" tab.
4. Select "Always". Note: Selecting the default recommended option "Only when necessary for correct rendering of the form (recommended)"will not solve this problem.

When you are using rules, you  must set the postback settings of the button to "Always" so that the click event sends data to the server everytime the button is clicked.

p.s. The error occurs in browser enabled forms.

Had this error too - thanks for the solution. Setting the control the conditional expression was checking to always post back to the server fixed the problem.

Hi. I'm now getting this null or not an object whenever I use my windows xp YAHOO internet browser.

Can anyone walk me through(step by step) to eliminate this?

See debugging infopath forms article on this blog. That article will help you in locating the source of the article. Once you know the source (control) that is causing the problem, you can follow the steps mentioned in this post to eliminate the error.

I am getting the same error by placing simple user control with button with click event. As soon as I click button, the error shows up and no infopath is involved. Please help ....

It depends on the control that you are using. Make sure the postback event of the control is set to true.

I am getting this error under different circumstances.  The problem only happens in IE.  It happens when a flash app calls a very simple javascript function in its container that does nothing more than add some HTML to the page using the innerHTML property.

The javascript is there, the DOM nodes are there, and IE was the browser that introduced innerHTML.  Does anyone know what IE doesn't like about this scenario?

In case it matters, I am using  AS3's externalInterface method to call the javascript, and the flash player we are using is version 9.

If you have multiple controls, make sure you change the postback settings of the control that causes the problem.
