ADF:LOV declarative component not working inside table component.

Question

Hi,
I have created a custome LOV control,I am using this custom LOV control inside the table component,I am passing the below values as the parameter
KeyValue="#{row.bindings.Value.inputValue}"
LovModel="#{row.bindings.Value.listOfValuesModel}"
Value- is the list of value attribute.
When i click on the LOV search icon, the popup displays the Query model(it displays the list name at the top in the search page.so it is able to recognise the LOVmodel) but it is not able to retrive the list values.I am getting Query page with no values
in the jspx page it is giving warning as "reference not found for row.bindings.Value.listOfValuesModel"
Please can anyone help me on this?
Thanks,
Harish

Hi Frank,
below is my actual requirement and the solution i tried till now.
I have a table and it has two columns let’s say “Columns” and “Values”. The first column i.e. “Columns” will be a dropdown and it will have predefined values, the other column “Values” will be a “List of value” control or similar kind of control in which the user can search and select multiple values from the popup list, and that list should dynamically bounded to the first column selected value.
For Ex: if I select a value “Product” from the dropdown of the first column “Columns” , the control in the other column “Values” should bound to “product” list and I should be able to search and select multiple values from the pop up. And the popup should return the multiple selected values as a comma separated string to the textbox.
In my requirement I have to use only VO’s to create the list and the control in the “Values” column should switch between these VO’s depending on the value selected in the first column.
The solution we tried till now.
I used a LOV switcher to achieve the above requirement. But we have a limitation in this approach as we could not do the multi select. Then we created a declarative LOV component in which we can select multiple values as a comma separated string from the popup.
I retained the LOV switch model , instead of binding LOV switch model to the basic “Input List of Value” control in the JSPX page ,I used the LOV declarative component. Below is the code snippet which calls the declarative LOV component from JSPX page.
<af:panelFormLayout id="pfl2">
<af:selectOneChoice value="#{bindings.Columns.inputValue}"
label="#{bindings.Columns.label}"
required="#{bindings.Columns.hints.mandatory}"
shortDesc="#{bindings.Columns.hints.tooltip}"
id="soc3" autoSubmit="true">
<f:selectItems value="#{bindings.Columns.items}" id="si5"/>
</af:selectOneChoice>
<mc:OraMultiSelect
KeyValue="#{bindings.Value.inputValue}"
LovModel="#{bindings.Value.listOfValuesModel}"
id="oms2"/>
</af:panelFormLayout>
Where Value attribute is having LOVModel.
The above code perfectly fine as I used it inside the “Form layout” and with the parameters passed as KeyValue="#{bindings.Value.inputValue}"
LovModel="#{bindings.Value.listOfValuesModel}"
The problem I am facing:
The actual problem comes when I use this control inside the table which I required in my implementation.
I called the declarative LOV control as shown below inside the table as I used to call the basic “Input List of value” control which works fine inside the table.
. <af:column sortProperty="Value" sortable="false"
headerText="#{bindings.OpPlanning1.hints.Value.label}"
id="c1" width="133">
<mc:OraMultiSelect KeyValue="#{row.bindings.Value.inputValue}"
LovModel="#{row.bindings.Value.listOfValuesModel}"
id="oms1"/>
</af:column>
Above code doesn’t works fine when I select value from the “Column” dropdown it displays the corresponding list model in the pop up but not able to retrieve the value of the list in the popup .
If I pass the parameters as
. <af:column sortProperty="Value" sortable="false"
headerText="#{bindings.OpPlanning1.hints.Value.label}"
id="c1" width="133">
<mc:OraMultiSelect KeyValue="#{bindings.Value.inputValue}" --instead of ="#{row.bindings.Value.inputValue}"
LovModel="#{bindings.Value.listOfValuesModel}"--}" --instead of ="#{row.bindings.Value.inputValue}"
id="oms1"/>
</af:column>
It works fine for the first row.The subsequent rows refers the value selected in the first row dropdown.
Thanks For the help,
Harish
