However, when unparking the request, some variables and components change their status to **NOT\_FROZEN\_BUT\_CHILDREN\_NEED\_ANALYZE** , making it possible to update their values. This happens in the visitor **UnfreezeUnparkedChildrensValuesVisitor**, which "unfreezes" the components on the request as well as the session variables that depend on them. So if we have a problem updating the value of a session variable after unparking, it is enough, for example, to create a technical field, set up a listener and **DATA SOURCE FROM ANOTHER FIELD** on this session variable, this way we will force its status to change from **FROZEN** to **NOT\_FROZEN\_BUT\_CHILDREN\_NEED\_ANALYZE.** --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.eximee.com/documentation/documentation-en/budowanie-aplikacji/interfejs-uzytkownika/formularze/zmienne-sesyjne/odmrazanie-zmiennych-sesyjnych-przy-odparkowaniu.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
