I would like to update the values of the following check boxes in the database
by using a form as shown below.
| <h:form id="category_form">
| <h:dataTable value="#{categoryFinder.categories}"
| border="1" var="category"
| rendered="#{not empty categoryFinder.categories}">
| <h:column>
| <f:facet name="header">Category</f:facet>#{category[0]}
| </h:column>
| <h:column>
| <f:facet name="header">Assigned</f:facet>
| <h:selectBooleanCheckbox id="categoryList" disabled="false"
| value="#{category[1] > 0}" />
| </h:column>
| <h:column>
| <f:facet name="header">Preferred</f:facet>
| <h:selectBooleanCheckbox id="PreferredList" disabled="false"
| value="#{category[2] == 1}" />
| </h:column>
| </h:dataTable>
| <h:commandButton id="savecategory" value="Save"
| action="#{categoryFinder.updateCategory}" />
| </h:form>
|
When I click the submit button, the page is rerendered and and the altered
check boxes are saved. But the action listener categoryFinder.updateCategory is
not invoked - which means no database update has been taken place.

I tried to stick to the examples in the Seam documentation. Is there any
suitable reason why this happens? I've been looking for a solution the wohle
day now :(
