Tag Summary 
TagDescription
set

Facelet tag handler that exposes an expression as a variable, and makes it possible to cache it.

This is very close to the c:set tag, but allows caching, and the variable is only exposed inside the tag. Note that this tag will not work as expected when used with iteration variables inside a standard table, for instance.

Example:
        <nxu:set var="actions" value="#{webActions.getActionsList('SUBVIEW_UPPER_LIST')}" cache="true">
          <nxu:dataList var="action" value="#{actions}">
            ...
          </nxu:dataList>
        </nxu:set>
      
methodResult

Facelet tag handler that exposes the result of a method binding as a variable. Note that this tag is deprecated since Seam 2.0 handles method resolution natively. The tag nxu:set can be used instead.

This is helpful to avoid having to define a getter on a class to get some rendering info. This is comparable to f:param or ui:param tags, but using method bindings instead of value bindings.

WARNING : the variable is only exposed inside the tag: this is a different behaviour than the c:set tag that can be closed immediately.

Example:
        <nxu:methodResult name="actions" value="#{webActions.getActionsList('SUBVIEW_UPPER_LIST')}">
          <nxu:dataList var="action" value="#{actions}">
            ...
          </nxu:dataList>
        </nxu:methodResult>
      
repeat

Facelet tag handler that performs an iteration.

This handler is very close to the facelets c:forEach tag handler. It holds additional configuration to handle ajax re-rendering of lists, avoiding potential JSF duplicate id issues, as well as cache issue, when the iteration list changes.

Example:
        <nxu:repeat items="#{layoutNames}" var="layout">
          <nxl:layout name="#{layout}" value="#{document}" />
        </nxu:repeat>
      
actionListenerMethod

Facelet tag handler that add an action listener to the parent component. Available since 5.3.1.

Parent needs to be an action source for the action listener to be declared on it.

This is useful when declaring several action listeners on the same parent component, and when the order of calls needs to be respected: the action listener method declared on a component is the first one called. So this method makes it possible to add other action listeners before it, without having to declare a class (when using the f:actionListener tag).

Since 5.6, this tag can resolve expressions twice, making it possible to use it with Nuxeo actions configured to reference an EL expression in their definition: first to call action#getLink and then to call the actual action defined by another EL expression.

Example:
        <h:commandLink value="Go">
          <nxu:actionListenerMethod value="#{myBean.performFirstAction}" />
          <nxu:actionListenerMethod value="#{myBean.performSecondAction}" />
        </h:commandLink>
      
selectItems

This tag is similar to the f:selectItems tag, except that it allows to iterate on any kind of data, and have control on the resulting selection values and labels.

It has been adapted to work with datamodel lists wrapped by Seam (when using the Datamodel annotation).

Examples:
        <nxu:selectItems value="#{myBean.myList}" var="item"
          itemValue="#{item.id}" itemLabel="#{item.title}" />

        <nxu:selectItems value="#{documentList}" var="document"
          itemValue="#{document.ref}" itemLabel="#{document.dublincore.title}" />
      
selectItem

This tag is similar to the f:selectItem tag, except that it allows to resolve the item from any kind of data, and have control on the resulting selection value and label.

Examples:
        <nxu:selectItem value="#{myBean.myElement}" var="item"
          itemValue="#{item.id}" itemLabel="#{item.title}" />

        <nxu:selectItem value="#{document}" var="document"
          itemValue="#{document.ref}" itemLabel="#{document.dublincore.title}" />
      
inputFile

Util tag to perform a complex file upload dealing with edition and deletion.

It only deals with Nuxeo Core blobs.

This tag uses a component that will handle its rendering using other existing components. It will present a radio menu with existing choices: upload a file, keep it (eventually change its filename), delete it, or do nothing. Choices will be presented automatically given values and tag attributes (is there a blob set, is there a filename, is the blob required, etc...).

It uses the nxu:outputFile related component rendering for the "keep" option and the tomahwak t:inputFileUpload tag for the "upload" option.

It is possible to use a facet named "download" to override the default "keep" option rendering (e.g the document download presentation).

Example:
        <nxu:inputFile value="#{document.file.content"
          filename="#{document.file.filename}"
          editFilename="true" />
      
validateFileSize

Registers an InputFileSizeValidator instance on the UIComponent associated with the closest parent UIComponent custom action.

Example:
        <nxu:inputFile value="#{document.file.content}"
          filename="#{document.file.filename}"
          editFilename="true">
          <nxu:validateFileSize maxSize="10Mo" />
        </nxu:inputFile>
      
validateFileMimetype

Register an InputFileMimetypeValidator instance on the UIComponent associated with the closest parent UIComponent custom action.

Example:
        <nxu:inputFile value="#{document.file.content}"
          filename="#{document.file.filename}"
          editFilename="true">
          <nxu:validateFileMimetype extensions=".jpg, .png" />
        </nxu:inputFile>
      
validateDocumentConstraint

Registers an DocumentConstraintValidator instance on the UIComponent associated with the closest parent input.

The bound value is resolved, and if it matches a document, the corresponding field constraints are checked (if not, no validation is performed).

Example:

        <nxu:validateDocumentConstraint handleSubProperties="false" />
      
outputFile

Util tag to perform a blob rendering, useful if a rest URL cannot be provided (on a JSF form postback for instance).

It only deals with Nuxeo Core blobs.

Display is an immediate link to the blob, with filename as link value if provided, together with the blob mimetype icon.

Example:
        <nxu:outputFile value="#{document.file.content}"
          filename="#{document.file.filename}" />
      
jsInputList

Tag that perform edition of a list of items.

It only deals with lists or arrays of serializable objects.

Example:
        <nxu:jsInputList value="#{currentDocument.files.files}"
          id="myId" model="model" diff="true"
          template="#{nxd:defaultValue('files', 'files')}">
          <h:panelGrid columns="2">
            <h:inputHidden>
              <f:passThroughAttribute name="name" value="myFormId:myId:#{isListTemplate ? 'TEMPLATE_INDEX_MARKER:': ''}rowIndex[]" />
              <f:attribute name="value" value="#{isListTemplate ? 'TEMPLATE_INDEX_MARKER' : model.rowIndex}"/>
            </h:inputHidden>
            <h:panelGroup>
              <a href="#" class="deleteBtn"
                 onclick="return nuxeo.utils.deleteFromList(jQuery(this).closest('.listItem'))" />
              <a href="#" class="moveUpBtn"
                 onclick="return nuxeo.utils.moveUpList(jQuery(this).closest('.listItem'))" />
              <a href="#" class="moveDownBtn"

                      <h:inputText value="#{model.rowData} />
                    </td>
                  </tr>
                </tbody>
              </table>
            </h:panelGroup>
          </h:panelGrid>
        </nxu:jsInputList>

        <a id="myId_add" href="#nogo"
           onclick="return nuxeo.utils.addFromListTemplate('myForm:myId', jQuery(this).prev());">
          <h:outputText value="#{messages['command.add']}" />
        </a>
      
inputList

Tag that perform edition of a list of items. Note that this tag is deprecated since Nuxeo 7.2: use nxu:jsInputList instead.

It only deals with lists or arrays of serializable objects.

This tags puts a model in the request which can be accessed to get information about each list item value.
