Passing parameter for the bean function that deletes record from DB

Question

I need to delete some record from the DB without updating the reset of the user screen.
I use commandButton with immediate attribute as true, because validation should be skipped.
So, I can't rely on backing bean values being updated, but need to pass a param to the function that does the delete (deleteTemplate) function below.
The value of this param is selected value in another comboBox called "template".
Code below is not parsing. Could you advise how to do it?
<a4j:commandButton id="deleteTemplate" value="Delete"
                         action="#{qtBeanParam.deleteTemplate(param['piPerformanceReturnsForm:template'])}" immediate="true" reRender="template,templateList,templateOwner,templateOwnerList"
                         styleClass="blue-button">
                    </a4j:commandButton>Error Parsing: #{qtBeanParam.deleteTemplate(param['piPerformanceReturnsForm:template'])}

Answer 1

Thank you for your reply.
Could I pass the value that is entered in some other field as a "parameter" though?
<f:param name="anyName" value="parameter" />
For example the value from the following comboBox?
<rich:comboBox id="template" width="250" value="#{qtBeanParam.templateName}" enableManualInput="true"
                              converter="#{templateConverter}" valueChangeListener="#{qtBeanParam.changeTemplate}" >
                              <a4j:support event="onselect" reRender="template,templateList" ajaxSingle="true" />
                              <a4j:support event="onchange" reRender="template,templateList" ajaxSingle="true" />
                         <f:selectItems id="templateList" value="#{qtBeanParam.templateList}" />
                    </rich:comboBox>
