UIX LOV default query setting

Question

When clicking on a flashlight next to an empty or blank “messageLovInput”, its "inputValue" being blank, the resulting LOV popup will show no records found. How can I set either the "inputValue" of the “messageLovInput” or search field in the LOV popup to a default value of “%”?
The LOV uix source is set to:
<listOfValues title="Data Source ID" searchText="${param.searchText}" searchAreaMode="filter">
I need to either set the “messageLovInput”, its "inputValue", to “%” or when the LOV popup is initiated to set its “searchText” to “%”. When set to “%” the LOV will show all records available in the LOV.

Hi Ed and Karyn,
Ed, in your example you add <parameters> tag for every search column of the table. I just use one in my application and it works. I hope my example will help :)
<messageChoice name="filterBy">
<contents>
<option text="Department ID" value="DEPARTMENT_ID"/>
<option text="Department name" value="DEPARTMENT_NAME"/>
</contents>
</messageChoice>
<event name="lovFilter">
<compound>
<null/>
<invoke method="setWhereClause" instance="${bindings.DepartmentsView1.viewObject}" javaType="oracle.jbo.ViewObject">
<parameters>
<parameter javaType="string" value="${empty param.filterBy ? 'DEPARTMENT_ID' : param.filterBy} LIKE '%${param.searchText}%'"/>
</parameters>
</invoke>
<invoke method="executeQuery" instance="${bindings.CustId.viewObject}" javaType="oracle.jbo.ViewObject"/>
</compound>
</event>
'DEPARTMENT_ID' in <parameter> is just a default value in case param.filterBy is null.
Note that I use value property of Choice to assign a table column for whereclause and text property for choice description. So you can write whatever in text to help user.
Also I have a question. I need my LOV window to be called from different UIX pages. Do you have an example of this? The problem is in updating different UIModels from one LOV window. At forum I was advised to write event handler to update provider depending on source parameter. But unfortunatly I don't know how to do so.
Thank you in advance.
