title: How to use if="some condition" in ZK template tag
body: <p>I have a &lt;template> tag in my ZUL file, and I want to use this template when some condition accured (for example, when some LABEL's value change to some text).</p>
  
  <p>Please look at below code... As you can see, "templateStatus" is my label's name, but it did not work.</p>
  
  <p>How can I fix this issue?</p>
  
  <pre><code>    &lt;template name="allTaskTemplate" var="allTask" if="templateStatus.value == 'allTask'"&gt;
          &lt;row&gt;
              &lt;label value="" /&gt;
              &lt;label value="@load(allTask.documentDTO.docTypeDTO.title)"/&gt;
              &lt;label value="@load(allTask.documentDTO.docNumber)"/&gt;
              &lt;label value="@load(allTask.documentDTO.docDateTime)"/&gt;
              &lt;label value="@load(allTask.assignerID)"/&gt;
              &lt;label value="@load(allTask.assigneeID)"/&gt;
              &lt;label value="@load(allTask.assignDateTime)"/&gt;
              &lt;label value="@load(allTask.assignDateTime)"/&gt;
              &lt;label value="@load(allTask.assignDateTime)"/&gt;
              &lt;label value="@load(allTask.assignDateTime)"/&gt;
              &lt;label value="@load(allTask.documentDTO.docTypeStateDTO.stateActionDTO.actionDTO.title)"/&gt;
              &lt;label value="@load(allTask.catalogDTO.catalogTypeDTO.title)"/&gt;
          &lt;/row&gt;
      &lt;/template&gt;
  &lt;/grid&gt;
