How To Fix UPWB165 - A stateless page cannot contain any dynamic components

SAP Error Message - Details

• Message type: E = Error

• Message class: UPWB - Messages for Development Class UPWB

• Message number: 165

• Message text: A stateless page cannot contain any dynamic components

What causes this issue?

You are editing an HTML page whose current status is not always known
by the server at runtime (stateless). This means the attribute 'keep
page context' of the page has the value '<EX><AB>FALSE</></>'.
The event administration of dynamic components is not possible on
stateless pages. The generated ABAP OO class must be adapted specially
here. Dynamic components are pushbuttons to execute planning functions,
layouts, documents, and tab pages (tab controls).
However, there is at least one dynamic component on the stateless page
you are editing.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Set the attribute 'keep page context' of the HTML page to '<AB>TRUE</>'
or remove all dynamic components from this page.

• What is the cause and solution for SAP error message UPWB165 - A stateless page cannot contain any dynamic components ?

  The SAP error message UPWB165, which states "A stateless page cannot contain any dynamic components," typically occurs in the context of SAP Web Dynpro applications. This error indicates that you are trying to use dynamic components (like views or UI elements that require state management) on a stateless page, which is not allowed.
  Cause:
  
  Stateless Page: The page is defined as stateless, meaning it does not maintain any session or state information between requests. This is often used for pages that do not require user interaction or do not need to remember previous user inputs.
  Dynamic Components: Dynamic components, such as certain UI elements or views that require state (like input fields, tables, etc.), cannot be used on a stateless page because they rely on session data to function correctly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Change the Page Type: If the page needs to contain dynamic components, consider changing the page type from stateless to stateful. This allows the page to maintain state information and use dynamic components.
  
  
  Remove Dynamic Components: If the page must remain stateless, you will need to remove any dynamic components from the page. Replace them with static components that do not require state management.
  
  
  Review Component Design: Ensure that the design of your Web Dynpro application aligns with the requirements of stateless and stateful pages. If you need to use dynamic components, plan to use a stateful page instead.
  
  
  Check Configuration: Review the configuration settings of your Web Dynpro application to ensure that the page is set up correctly according to your design requirements.
  
  
  Related Information:
  
  Web Dynpro Documentation: Refer to the official SAP Web Dynpro documentation for more details on stateless and stateful pages, as well as guidelines for using dynamic components.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other developers who may have encountered similar issues.
  Debugging: Use debugging tools within the SAP environment to trace the execution flow and identify where the error is being triggered.
  
  By following these steps, you should be able to resolve the UPWB165 error and ensure that your Web Dynpro application functions as intended.
