Too many components (ADF?)
The following describes a problem I am having using Oracle ADF as
shipped with the JDevStudio final release 10.1.3.0.4. I've posted the
problem to the Oracle Jdeveloper Forum and got an immediate show of
interest from Oracle but nothing since then in terms of a clue as to
whether this is a solvable problem or not. I'd be interested to know if
anyone in the non-ADF community has run into a similar problem and
whether anyone from Oracle can tell me if this is an ADF bug or a
JDeveloper bug and if there is a work-around (other than just reducing
the number of components on a page).
My page has finally gotten so complex that the stack overflows and the
application just aborts. I can remove a couple of components and the
page works fine. It doesn't seem to matter which components I remove;
when I navigate to the page the following appears in my Embedded OC4J
Server log.
Debugger connection to debuggee process has been lost.
Process exited.
Debugger disconnected from local process.
The _MyPage_jspx.java file is over 500K and the class file is about
110K. If I remove some components and get the total _MyPage_jspx.java
file under 500K then the page works again.
The page includes a lot of application controls and a number of tables
that are used to display and edit attribute data. Most of these tables
include nested tables inside of their detailStamps. Rows in a table of
streets have tables of sites. This is where things start to fail.
Sometimes (but not always) I get a message that tells me that could not
find the StackOverflowError class so I have tried adding a -Xss1024k
option to my Java options but this didn't help; neither did -Xss2048k.
I am highly confident that the problem is not caused by the code itself
as I can remove any panelGroup or panelForm set on the page and it
works. I put any back and it fails. It is just too many components.
Everything compiles fine but JDeveloper just disconnects from the
application when the page is opened.
The following is some simple JSP code that demonstrates the problem.
Include-0.jspf
<af:panelBox text="Bottom include file has 3 panelForms" >
<af:panelHorizontal>
<af:panelForm rows="1" maxColumns="1">
<af:inputText label="Lorem ipsum" rows="3" wrap="true"

ultrices, tortor leo aliquet turpis." />

</af:panelForm>
</af:panelHorizontal>
</af:panelBox>
I included this in another jspf file
Include-1.jspf
<af:panelBox text="Include-1.jspf includes Include-0.jspf 5 times.">
<jsp:directive.include file="/Include-0.jspf" />
<jsp:directive.include file="/Include-0.jspf" />
<jsp:directive.include file="/Include-0.jspf" />
<jsp:directive.include file="/Include-0.jspf" />
<jsp:directive.include file="/Include-0.jspf" />
</af:panelBox>
I include that in another jspf
Include-2.jspf
<af:panelBox text="Include-2.jspf includes Include-1.jspf 5 times.">
<jsp:directive.include file="/Include-1.jspf" />
<jsp:directive.include file="/Include-1.jspf" />
<jsp:directive.include file="/Include-1.jspf" />
<jsp:directive.include file="/Include-1.jspf" />
<jsp:directive.include file="/Include-1.jspf" />
</af:panelBox>
And that is referenced by my jspx page.
TooManyComponents.jspx
<?xml version='1.0' encoding='windows-1252'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="1.2"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"

<jsp:text>
<![CDATA[ ><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01
Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> ]]>
</jsp:text>
<jsp:directive.page contentType="text/html;charset=windows-1252"/>
<f:view>
<afh:script source="/jscript/view_tools.js"/>
<af:document rendered="false">
<af:form id="notloggedin">
<af:panelPage title="This never happens but it mirrors my
problem layour">
<jsp:directive.include file="header.jspf"/>
<af:commandMenuItem text="You are not logged in. Please click
this message to be re-directed to the Login Page" action="login"/>
</af:panelPage>
</af:form>
</af:document>
<af:document rendered="true">
<af:form id="loggedin">
<af:panelPage title="Too much of a good thing?">
<jsp:directive.include file="/header.jspf"/>
<jsp:directive.include file="/Include-2.jspf" />
</af:panelPage>
</af:form>
</af:document>
</f:view>
</jsp:root>
This particular setup yeilded me the following error
Fatal error: Cannot find class java/lang/StackOverflowErrorProcess
exited.Debugger disconnected from local process.
If I put a second
<jsp:directive.include file="/Include-2.jspf" />
in my jspx file I get the following compile time error.
Error: code segment of method
_jspService(javax.servlet.http.HttpServletRequest,
javax.servlet.http.HttpServletResponse) too large
If I remove one of the jsp:include directives from my Include-1.jspf so
that it reads as follows:
<af:panelBox text="Include-1.jspf includes Include-0.jspf 4 times.">
<jsp:directive.include file="/Include-0.jspf" />
<jsp:directive.include file="/Include-0.jspf" />
<jsp:directive.include file="/Include-0.jspf" />
<jsp:directive.include file="/Include-0.jspf" />
</af:panelBox>
The application works.
I took all the JDeveloperStudio defaults for creating my project.

I think you should post that to the ADF faces user list.
