This is the jsf page:
<p:dataTable editable="true" editMode="cell" var="data"
value="#{tableBean.dynaObjectList}" scrollable="true"
scrollWidth="100%" scrollHeight="100%">
<p:ajax event="cellEdit" immediate="true"
listener="#{tableBean.onCellEdit}" />
<c:forEach items="#{tableBean.columns}" var="column"
varStatus="loop">
<p:column sortBy="#{data.map[column.property]}"
headerText="#{column.header}">
<p:cellEditor>
<f:facet name="input">
<p:inputText
value="#{data.map[column.property]}" />
</f:facet>
<f:facet name="output">
<h:outputText
value="#{data.map[column.property]}" />
</f:facet>
</p:cellEditor>
</p:column>
</c:forEach>
</p:dataTable>
Normally, for viewing the data , there is not any restriction.
I added inline editing support to the table and can't set the value.
When i tried LazyDynaMap like mentioned at the wiki, I am only able to add
one data value, because the map has keys with properties.
So if i have a DynaBean list which has properties like firstname, lastname
firstname=Ercan lastname=Canlier
firstname=Ercan2 lastname=Canlier2
Map will include only Ercan2 because the key is firstname for instance.
How can i create Dynamic table from the DynaBeans which will be also
editable?
Wiki information like below:
*2. LazyDynaMap
<http://commons.apache.org/proper/commons-beanutils/javadocs/v1.9.2/apidocs/org/apache/commons/beanutils/LazyDynaMap.html>*
is a *light weight* DynaBean facade to a Map with all the usual *lazy*
features. Its *light weight* because it doesn't have an associated DynaClass
containing all the properties. In fact it actually implements the DynaClass
interface itself (and MutableDynaClass) and derives all the *DynaClass*
information from the actual contents of the Map. A LazyDynaMap can be
created around an existing Map or can instantiate its own Map. After any
DynaBean processing has finished the Map can be retrieved and the DynaBean
*facade* discarded.
If you need a new Map then to use....
DynaBean dynaBean = new LazyDynaMap(); // create DynaBean
dynaBean.set("foo", "bar"); // simple
dynaBean.set("customer", "title", "Mr"); // mapped
dynaBean.set("address", 0, addressLine1); // indexed
Map myMap = dynaBean.getMap() // retrieve the Map
*or* to use with an existing Map ....
Map myMap = .... // exisitng Map
DynaBean dynaBean = new LazyDynaMap(myMap); // wrap Map in DynaBean
dynaBean.set("foo", "bar"); // set properties
