Man, this is taking way too long. I have the following. The line marked
with **** contains an @If. I set a breakpoint in showChildren() and
after it evaluates to true it doesn't get called by @If again (!?). This
basically means that if a menu item is selected then all of it's
children act as if they are selected too. I check the @IfBean source and
there doesn't seem to be any like caching or anything going on. I'm very
confused and help would be appreciated.
<renderblock jwcid="@RenderBlock" block="component:nav" />
<block jwcid="[EMAIL PROTECTED]" >
<ul>
<for jwcid="@For" source="ognl:items" value="ognl:item">
<li jwcid="@Any" class="ognl:cssClass">
<div><div><a jwcid="@DirectLink"
listener="listener:selectAction"
parameters="ognl: { item.section, item.page}" id="ognl:item.id"><span
jwcid="@Insert" value="ognl:item.label" /></a></div></div>
**** <span jwcid="@If" condition="ognl:showChildren()">
rendering children for <span jwcid="@Insert"
value="ognl:item.section" />
<renderblock jwcid="@RenderBlock"
block="component:nav" />
</span>
</li>
</for>
</ul>
</block>
here is showChildren()
public boolean showChildren() {
NavItem item = getItem();
return item.isSelected() && item.hasChildren();
}
