从Java Bean显示或隐藏Jsf Richfaces模式面板

Question

In JSF Richfaces , I need to show or hide modalpanel and GIF image from bean according to certain functions.

For example, after I have entered all values and click submit means, processing GIF image will be displayed. At the time of completion it gets hidden by using

  onclick="#{rich:component('wait1')}.show()",
  oncomplete="#{rich:component('wait1')}.hide()"

wait1 is an image file name I have used.

At the time of submitting, I have been validating the required fields.

If its empty, I want to hide the process image and show the modalpanel to get value from user.

How to hide the processing image and display the modal panel to get input from user, from java back bean?

Thanks in advance

Answer 1

I am suggesting you a solution. Create Modal panel with property "showWhenRendered" . create modalpanel as

 <rich:modalPanel id = "idd" autosized="true" width="500" height="50"
  showWhenRendered = "#{bean.booloeanvalue}">
  </rich:modalPanel>

In Bean, create boolean variable booloeanvalue. If booloeanvalue is true, automatically modalpanel is rendered and came to display.
