Hi,

I have defined a Tamino Schema which had been attached in this message. I successfully ran the X-Application generator to generate the jsp application for the schema.

I could launch the search.jsp successfully in the browser. However, when launching the create.jsp, the following error message occurred in the browser.

=============================================
An error occurred in the application program. Please report the following problem to your webmaster.

At the same time, there was an error message in the tomcat server console. Just like this:

Hello,

I installed your application and could reproduce your error. The reason is a bug when generating optional fields for new document. The element
?EndDate? of the element ?DatesOfAttendance? was not created correctly. I could fix this error.

The attached zip file contains
a) the modified source code of the class Schema.

Therefore, the following file of your existing X-Application installation will be overwritten:
- xapplication_313/src/com/softwareag/xtools/xapplication/businessdocument/Schema.java

If you want to install this fix execute the following steps:

Installation:

1. Extract the zip into the same directory where you extracted the xapplication_3_1_3.zip (parent directory of your xapplication_313).
2. Open a console.
3. Change to your directory xapplication_313.
4. Invoke ‘build’.
5. If started, shutdown your Tomcat.
6. Copy the new jar file ‘…\xapplication_313\lib\opt\xapplicationjar’ into the WEB-INF\lib directory of your generated application.
7. Startup Tomcat
8. Open an Internet Brower and invoke your application

I hope it helps you.

Bye,
Christian.

Hi,

Thanks for your help! I will try it later.

Hello,

this bug is fixed for X-Application 4.1.1. Please be aware that the handling for optional nodes differs to the former version.

While X-Application 3.1.3 created ‘minimal’ new documents, X-Application 4.1.1 creates new documents with all of its optional nodes (maximal documents). To switch this behavior, the limitaions section and the readme file contain a topic how to do this.

Furthermore, applications generated by X-Application 4.1.1 have functionality to add / delete optional node on the create and modify page.

Bye,
Christian.
