#1 DndDiv.xhtml incorrect

[Alberto Fernández]

missing a closing tag of the first "div" (and only) of template

my server shows the following error:

javax.servlet.ServletException: Error Parsing //C:/Program%20Files%20(x86)/jboss-5.1.0.GA/server/default/deploy/Sergas.war/WEB-INF/lib/dojo-faces-1.2_02.jar/META-INF/tags/DndDiv.xhtml: Error Traced[line: 65] The element type "div" must be terminated by the matching end-tag "</div>".

DndStoreMap

[Alberto Fernández]

I've noticed that the functionality is not implemented.
Here I post a simple solution.

At dojoHelper.java add:

public DndStoreMap getDndStore() {
return new DndStoreMap();
}

Copy attached files:
DndStoreMap.java -> org.j4fry.dojo.beans
DndDiv.xhtml -> META-INF/tags

It's all.

Simple working example:

At foo.xhtml, whitin dojo:form:

<dojo:dndDiv id="srcVegetales" type="source" styleClass="dndContainer"
items="\#{testFormBean.vegetales}" key="\#{item.name}" var="item" attr="" />

<dojo:dndDiv id="dstVegetales" type="target" styleClass="dndContainer"
items="\#{testFormBean.dndVegetales}" key="\#{item.name}" var="item" attr="" />
<!-- insertClass="es.atos.test.domain.Vegetal" -->

At fooBean.java:

// source
public List<Vegetal> getVegetales() {
return vegetales.getVegetales();
}

// target

private List<Vegetal> dndVegetales;

public void setDndVegetales(List<Object> dndVegetales) {
logger.info("fijando vegetales = " + dndVegetales);
HashMap<String, Vegetal> vegetalesMap = (HashMap<String, Vegetal>) vegetales.getVegetalesMap();
this.dndVegetales = new ArrayList<Vegetal>();
for (Object o : dndVegetales) {
if (o instanceof Vegetal) { // insertClass is set
this.dndVegetales.add(vegetalesMap.get(((Vegetal) o).getName()));
} else if (o instanceof String) { // insertClass is not set
this.dndVegetales.add(vegetalesMap.get((String) o));
}
}
}

public List<Vegetal> getDndVegetales() {
return dndVegetales;
}

Notes:
* if insertClass is set, then the objects passed to setter are instances of the
type declared in that param
* if no key param is defined, then assumes the list is of type List<String>, don't use
insertClass in that case
* the dndDiv not allow to insert duplicates

DndStoreMap (rev. 2)

[Alberto Fernández]

Rev 2 : improvement in order to indicate the property of the object to be displayed in the dndDiv container (by default -if not present mapValue parameter- shows key property) (when using lists of user objects, not string list); parameter key is now mapKey; new parameter mapValue

Example (List<Vegetal>) ----------------------------------

<dojo:dndDiv id="srcVegetales" type="source" styleClass="dndContainer"
items="\#{testFormBean.srcDndVegetales}" mapKey="\#{item.id}" mapValue="\#{item.name}" var="item" insertClass="es.atos.test.domain.Vegetal" attr="" />

<dojo:dndDiv id="dstVegetales" type="target" styleClass="dndContainer"
items="\#{testFormBean.dstDndVegetales}" mapKey="\#{item.id}" mapValue="\#{item.name}" var="item" insertClass="es.atos.test.domain.Vegetal" attr="" />

public void setSrcDndVegetales(List<Object> srcDndVegetales) {
this.srcDndVegetales = new ArrayList<Vegetal>();
for (Object o : srcDndVegetales) {
if (o instanceof Vegetal) { // insertClass is set
this.srcDndVegetales.add(vegetales.findById(((Vegetal) o).getId()));
} else if (o instanceof String) { // insertClass is not set
this.srcDndVegetales.add(vegetales.findById((String) o));
}
}
}

public List<Vegetal> getSrcDndVegetales() {
if (this.srcDndVegetales == null) {
this.srcDndVegetales = new ArrayList<Vegetal>(vegetales.getVegetalesMap().values());
}
return this.srcDndVegetales;
}

public void setDstDndVegetales(List<Object> dndVegetales) {
logger.info("fijando vegetales destino = " + dndVegetales);
this.dstDndVegetales = new ArrayList<Vegetal>();
for (Object o : dndVegetales) {
if (o instanceof Vegetal) {
this.dstDndVegetales.add(vegetales.findById(((Vegetal) o).getId()));
} else if (o instanceof String) {
this.dstDndVegetales.add(vegetales.findById((String) o));
}
}
}

public List<Vegetal> getDstDndVegetales() {
return dstDndVegetales;
}

Example (List<String>) -------------------------

<dojo:dndDiv id="srcVegetalesStr" type="source" styleClass="dndContainer"
items="\#{testFormBean.srcDndVegetalesStr}" var="item" attr="" />

<dojo:dndDiv id="dstVegetalesStr" type="target" styleClass="dndContainer"
items="\#{testFormBean.dstDndVegetalesStr}" var="item" attr="" />

public void setSrcDndVegetalesStr(List<Object> srcDndVegetales) {
this.srcDndVegetalesStr = new ArrayList<String>();
for (Object o : srcDndVegetales) {
if (o instanceof Vegetal) { // insertClass is set
this.srcDndVegetalesStr.add(((Vegetal) o).getName());
} else if (o instanceof String) { // insertClass is not set
this.srcDndVegetalesStr.add((String) o);
}
}
}

public List<String> getSrcDndVegetalesStr() {
if (this.srcDndVegetalesStr == null) {
this.srcDndVegetalesStr = vegetales.getVegetalesNames();
}
return this.srcDndVegetalesStr;
}

public void setDstDndVegetalesStr(List<Object> dndVegetales) {
this.dstDndVegetalesStr = new ArrayList<String>();
for (Object o : dndVegetales) {
if (o instanceof Vegetal) {
this.dstDndVegetalesStr.add(((Vegetal) o).getName());
} else if (o instanceof String) {
this.dstDndVegetalesStr.add((String) o);
}
}
}

public List<String> getDstDndVegetalesStr() {
return dstDndVegetalesStr;
}

DndDiv (rev. 3)

[Alberto Fernández]

In the third revision of DndDiv.xhtml, we can now define the type of items accepted by a dndDiv container, through the parameter "accept" (ej accept="vegetal,animal")
Typically for containers that act as target.

The parameter "nodeType" allow to define type of nodes which contains a dndDiv. Typically for sources.

Example:

<dojo:dndDiv id="srcVegetales" type="source" nodeType="vegetal" styleClass="dndContainer" items="\#{testFormBean.srcDndVegetales}" mapKey="\#{item.id}" mapValue="\#{item.name}" var="item" insertClass="es.atos.test.domain.Vegetal" attr="" />

<dojo:dndDiv id="dstVegetales" type="target" accept="vegetal" styleClass="dndContainer" items="\#{testFormBean.dstDndVegetales}" mapKey="\#{item.id}" mapValue="\#{item.name}" var="item" insertClass="es.atos.test.domain.Vegetal" attr="" />

<dojo:dndDiv id="srcVegetalesStr" type="source" nodeType="otroVegetal" styleClass="dndContainer" items="\#{testFormBean.srcDndVegetalesStr}" var="item" attr="" />

<dojo:dndDiv id="dstVegetalesStr" type="target" accept="otroVegetal" styleClass="dndContainer" items="\#{testFormBean.dstDndVegetalesStr}" var="item" attr="" />

showRoom dnd.xhtml (example)

[Alberto Fernández]

beans DndBean (example)

[Alberto Fernández]

Example to add to JSFExamples:

1) Copy DndBean.java to package org.j4fry.beans
2) Copy dnd.xhtml to WebContent/showRoom
3) Modify common.xhtml and add the following line in a appropiate place (around line 90):

<a href="${request.contextPath}/showRoom/dnd.faces" target="_self" class="fishMenu">Dnd</a><br />

4) I've also modified class Car at package org.j4fry.domain, adding this two methods, to get and set an extended description of the car (in this example de setter should be, but it is not necessary to do something)

public void setLongDescription(String longDescription) {
// nothing
}
public String getLongDescription() {
return String.format("%s (%s mph)", getName(), getSpeed());
}
