Issue with clearing the LOV field

Question

Hi,
Could someone please help me with the code to reset/clear the value of an LOV field.
I have a messageChoice and an LOV on the page. My requirement is that when a value is selected from the messageChoice, the value populated in the LOV field needs to get cleared.
I have defined a PPR event for the messageChoice bean and I am handling it in the PFR of the CO.
However, the below code does not clear the LOV field.
lovBean.setValue(pageContext, null);
lovBean.setText(pageContext, null);
If I add the statement lovBean.setText(""), then the value selected from the LOV window does not get populated in the LOV field in the base page.
The LOV is based on a VO and has just a single result mapping defined.
Thanks.

As per OAF standards, you cannot set a bean value in process form request, i.e. methods like
lovBean.setValue(pageContext, null);
lovBean.setText(pageContext, null);
You can clear LOV using either of the ways:
1)Redirect the flow to process request from process form request,i.e redirect to same page and then set value using
lovBean.setText(pageContext, null
2) in process form request , get the VO row attached to the LOV and update the corresponding attribute value as null.
