icefaces visible =“＃{graphicDataController.drawingItems.size（）> 0}”到CSS样式属性(icefaces visible=“#{graphicDataController.drawingItems.size() > 0 }” to CSS style attribute)

 因为，Primefaces没有Icefaces那样的可见属性。 因此，我将visible =“false”迁移到style =“display：none”并将visible="true"迁移为style="display: inline"作为Primefaces属性。 
 
 但是，我必须迁移visible="#{graphicDataController.drawingItems.size() > 0 }"或类似这样的东西visible="#{workbasketBean.isCurrenTaskAvailable() or workbasketBean.currentProcessAvailable() }" 
 
 我想使用类似这样的东西style="display: #{bean.prop ? 'inline' : 'none'}"而不是bean.prop ，我有这个复杂的表达式workbasketBean.isCurrenTaskAvailable() or workbasketBean.currentProcessAvailable() 。 
 
 我不知道如何在CSS中评估这个复杂的表达式workbasketBean.isCurrenTaskAvailable() or workbasketBean.currentProcessAvailable() 。

Because, Primefaces does not have a visible attribute as Icefaces has. So, I migrated the visible="false" to style="display: none" and visible="true" to style="display: inline" as a Primefaces attribute.
 
However, I have to migrate also visible="#{graphicDataController.drawingItems.size() > 0 }" or something like this visible="#{workbasketBean.isCurrenTaskAvailable() or workbasketBean.currentProcessAvailable() }"
 
I want to use something like this style="display: #{bean.prop ? 'inline' : 'none'}" but instead of bean.prop, I have this complex expression workbasketBean.isCurrenTaskAvailable() or workbasketBean.currentProcessAvailable(). 
 
I do not know how to evaluate this complex expression workbasketBean.isCurrenTaskAvailable() or workbasketBean.currentProcessAvailable() inside of CSS.
