Web Application Crashes (PB 11.5 Build 3127)

Former Member

Hi Everyone,

First of all, I am newbie when it comes to using PB 11.5 (so please bear with me).  I would like to ask for help regarding my issue. IE browser crashes with a message like this "Unexpected error was thrown, the browser will be closed! Please report the error to the administrator. Error:'dw.gobs.computed_field1' is null or not an object." This happens every time the web application loses focus. One example scenario, user inputs data in web application then he receives a message from Yahoo! messenger or user clicks on another application like MS Word, when the user goes back to the web application it crashes with the message I mentioned above.

This application works fine in PB Client/Server but the web version does not. The application requires an excel type input and needs to auto-compute some fields (like the 'computed_field1') every time the user changes rows or columns.


The 'computed_field1' Compute Expression is currently set as 'sum (col1 for all)', all col1 have zero values after database retrieval. And the user inputs in col2, so as far as I know 'computed_field1' value should remain the same. I have used here grid and tabular as presentation styles but it is giving me the same error. There are no codes in the ItemChanged event.

Please advise for any possible solution or workarounds.

thanks in advance.

regards,

Jeffrey

Hi Jeff;

  Yes, I have seen that error before and many others. Looks like you are trying to use the WebForms feature from the overall description of the issue.

1) Webforms is EOL and was removed from the product in PB 12.5.2

2) Webforms does not work well with W7

3) Webforms will not work with W8

4) Webforms will not work with IE 11

5) Webforms has many issues with IE 10

I am not sure what to tell you on your computed column issue. I highly doubt that SAP technical support will assist you in resolving this as  the feature is no longer supported. Also, Sybase removed all the older PB 11.x MR & EBF's from their website when they EOL'ed Webforms. So I am not even sure if you can get the 11.5.1 MR to see if that helps you.

  If you are open to another route, I would strongly recommend having a look at the Appeon Web product and porting your Webform application over to that technology. Appeon already supports 64 bit, IE 11.1 (W8), mutithreaded / reentrant code execution, etc. FYI: http://www.appeon.com

PS: I switched to Appeon in 2008 and never looked back!

Thank you for the reply, Chris.  The compatibility issue is one of the problems we encounter here as machines are being replace with Win7 OS installed on it.  This web application is just for temporary use, so switching to another route is not an option.
