1. login as "admin"
2. using the customizer of admin,
(by clicking the image "customize" at the top right corner of web page )
create a pane named "ROOT" and switch the layout type from "One column" default to "Menu pane" .
(*** here the button "Add pane" is disabled. )
3. using the customizer of pane ROOT's own , (by clicking the image "customize" beside the hyperlink "ROOT"), click the button "Add Pane" that is ENABLED, create a subpane named "CHILD" and enter into its customized page, click the button "Add Portlet",add 3 portlets , select "Three Columns(33/33/33)" layout, then apply all and return the home page of admin.
4. using the customizer of ROOT's own again,
when i switched the layout from "Three Columns(33/33/33)" to "One column" ,
a error occured :
the first portlet disappeared !!! there only left 2 portlets on the web page.
This is the PSML section about the pane "ROOT" :
<portlets id="P-f6f92d0717-10010">
<metainfo>
<title>ROOT</title>
</metainfo>
<security-ref parent="owner-only"/>
<layout position="4" size="-1"/>
<control name="MenuControl"/>
<controller name="MenuController"/>
<portlets id="P-f6f93780ae-10011">
<metainfo>
<title>CHILD</title>
</metainfo>
<security-ref parent="owner-only"/>
<layout position="0" size="-1"/>
<controller name="ThreeColumnsSymetric"/>
<entry id="P-f6f937c9a3-10012" parent="HelloVelocity">
<layout position="-1" size="-1">
<property name="column" value="0"/>
<property name="row" value="0"/>
</layout>
</entry>
<entry id="P-f6f937c9a3-10013" parent="ForwardDemo">
<layout position="-1" size="-1">
<property name="column" value="1"/>
<property name="row" value="0"/>
</layout>
</entry>
<entry id="P-f6f937c9a3-10014" parent="HelloVelocityCached">
<layout position="-1" size="-1">
<property name="column" value="2"/>
<property name="row" value="0"/>
</layout>
</entry>
</portlets>
</portlets>
I made an attempt to locate the error that puzzled me in our project at the same time by using JBuider 8 's debugger but got nothing up to now.
Finally, sorry for my poor english because i'm a Chinese girl and hope that you can understand what i said, ^_^ .
best regards, lark
