Where to report MyFaces 1.1.5 (major) bug? (problem with facet tag)
Using a facet tag inside a datatable for a column header has been broken (worked before, now does not). I searched the wiki but did not see a place I could post a bug. If you do something like this: you get a duplicate ID error. the f:facet tag seems to be the culprit. The page displays properly on load but if you come back to the page, there will be an exception thrown citing duplicate ID's. Notice there are no use of id's. The duplicate ID problem is due to MyFaces generated id's. not sure how to fix this but you would be wise to not upgrade to 1.1.5 just yet until this is fixed. -- View this message in context: http://www.nabble.com/Where-to-report-MyFaces-1.1.5-%28major%29-bug--%28problem-with-facet-tag%29-tf3329824.html#a9258785 Sent from the MyFaces - Users mailing list archive at Nabble.com.
Re: [Solved] Never before seen exception (facelets.FaceletViewHandler handleRenderException) - ??
I am using 1.1.5 latest release. Seems to be something new in 1.1.5 as a
previous snapshot of 1.1.5 we were using did not cause the problem.
the duplicate id being reported is generated by the system. others are
beginning to see the bug as well. I believe it is a problem with MyFaces
and not a problem with any individual project or problem.

no, the bug or problem is with myfaces. the duplicate id being reported is
generated by the system. not sure what to do except request that myfaces be
fixed.

Re: [Solved] Never before seen exception (facelets.FaceletViewHandler handleRenderException) - ??
The duplicate ID's are reported on facelets generated id's so it is a
facelets bug. I see this when I use the facet tag.

Re: [Solved] Never before seen exception (facelets.FaceletViewHandler handleRenderException) - ??
I found the culprit. It is the facet tag (no id's) I think there is a bug in MyFaces 1.1.5. This was working before but now has problems. It has nothing to do with duplicate id's that the user provides but ID's that MyFaces generates.

I removed all included files. Also if it displays properly the first time
(indicating no duplicate id's) why would it fail the second time I try the
page?

I checked everywhere, even grep'd through everything and there is no

This is super helpful and will look into it. Ideally what I am looking for

Re: [Solved] selectList - how to pass a parameter to backing bean method from XHTML?
Actually the data to build the select list is stored in a database. We have
a function that when passed a column value (the code type) will return a
List. So the only thing I need to accomplish is to get this
String (the codeType) to the method from the XHTML (do not want to put in
the backing bean).
thanks

Re: [Solved] selectList - how to pass a parameter to backing bean method from XHTML?
I tried the following but could not get it to work:
And in the BB to retrieve the codeType I have the following method that is
called:
private String getCodeType()
{
String codeType = (String)FacesContext.getCurrentInstance()
.getExternalContext().getRequestParameterMap().get("codeType");
return codeType;
}
---
When I look at the value for "codeType" it is always null. getCodeType is
called by
public List getSelectList() {
// query from types table here and pass codeType (call to getCodeType()
which uses faces context
// to get a param set in the XHTML.
}

Re: [Solved] selectList - how to pass a parameter to backing bean method from XHTML?
We need to build a pulldowns (select list boxes) on the front end (select
lists, check boxes etc) and do not want to write a getter for each one. We
simply want a generic method that we call throughout the application called
"getList(String s).
String s is a key into a types table that, when used for the query will
return everything needed in the list.
I thought this would be the simplest approach instead of having to write a
method that sets a string and passes it to a function that builds
List.
It would be better to simply have the String s in the XHTML, that calls 1
method (used throughout the app) that will build and return the
List based on the string (param) in the XHTML.
at first look it seems like would work but I can not seem to get
this to work to pass any params to my backing bean.

selectList - how to pass a parameter to backing bean method from XHTML?
I want to build a SelectItem list by calling a method in my backing bean, but
I want to be able to pass the backing bean a String (from the XHTML).
---
This is what I currently have:
where vehicleTypeList is a method in CarBean.getVehicleTypeList()
---
So I want to change the method signature to accept a String like so:
CarBean.getVehicleTypeList(String s)
and in the XHTML pass String s to CarBean.getVehicleTypeList(String s).
Is this possible?
value="#{carBean.vehicleTypeList("myString")}"
thanks
Lisa

RE: and image of button - how not to hard code
But this requires hard coding of the path to spacer.gif. What we are trying
to do is implement skins so that the user can change the look and feel of
the web page and may decide to choose bigger buttons which may require a
change to spacer.gif(?). Not really sure. will experiment with this and
see what happens.
thanks for the help.

managed-bean - request scope question
As I understand it a managed-bean that is request scope will get instantiated each time (a request is submitted) and then destroyed (or sent for garbage collection) after the response. I put some print statements in the no arg constructor and see that it is instantiated (and all setters called with Spring injection) the first time the page is requested, but then when I hit other buttons on the page (subsequent requests), I do not see the bean re-instantiated (and setters called) etc. any ideas? I have seen some beans that get instantiated on every request, but the few that I am working with don't. I have checked my config file and it is indeed in "request" scope. It acts like it is in session scope or something. I should see the no-arg constructor called each time for a request. thanks L -- View this message in context: http://www.nabble.com/managed-bean---request-scope-question-tf3198755.html#a8880992 Sent from the MyFaces - Users mailing list archive at Nabble.com.

Re: When does saveState occur?
I'm not seeing that the values are restored at the beginning. I must have something wrong. I have a BB that has 3 setters called after instantiation.

RE: JSF lifecyle - managed-bean
We are using Spring in other parts of the framework but not on our Backing Beans. This would take some rework to use Spring on the front-end beans. Also upgrading to Spring 2.0 would take some work as well and we are already behind. I am aware that you can do this in Spring but could not find an easy way to do it in JSF.

If I have in my bean. On a managed bean, when does saveState (restoring of values) actually occur? 1. before the setters listed in the managed-bean? 2.

I have a button that is rendered based on a boolean variable. The button (a
save button) gets rendered on the page. I enter information into the form
and click the [Save] button.
I then get an exception in my browser:

I go to my xhtml file and check the spelling and syntax of the action method
(as well as the backing bean syntax and correctness). Everything is
correct. I put print statements at the beginning and end of my
ActionListener and it gets executed completely all the way through.
For the life of me, I can not figure out why the Action method does not get
executed. It has the correct signature: public String mainViewAction() {
}

Re: problems (not working / have tried everything)
I put two methods in my BB that I understand should be called during the
serialization/deserialization process that invokes.
I do not see in my Tomcat log that these two methods are being called. Does
this mean that is indeed not working in my case?
The methods I put in my BB that the xhtml references (which contains
are as follows:
private void readObject(ObjectInputStream stream)
throws IOException, ClassNotFoundException {
stream.defaultReadObject();
System.out.println("--- Deserialization (saveState):
PtGroupAdmin.readObject() ---");
}
private void writeObject(ObjectOutputStream stream)
throws IOException, ClassNotFoundException {
stream.defaultWriteObject();
System.out.println("--- Serialization (saveState):
PtGroupAdmin.writeObject() ---");
}
The fact that neither of these are called in my BB indicate that
(for some reason) is not working in my project. I am sure it
works, but there may be some odd reason (config) it is not working here.
Any help would be appreciated. I inherited this framework and am trying to
find out if it works like people think that it is. Would putting these two
methods in my BB be in indication that the and Serrialization
are working correctly or am I on the wrong path?

Re: commandLink not working ??
I put a tag at the bottom of the main page and did not see
anything as far as a validation error goes. The listener and action are
quite simple. Not sure why it is not hitting it. It appears that there are
no validation errors and the Listener and Action are not being executed by
the commandLink. We are using tomahawk 1.5
I also put in immediate="true" in the commandLink which is supposed to
bypass the validation phase, but it will still not hit the Listener or the
action. The command link works the first time but not the second. The
commandLink is in a popup section. The main page code and the popup code
are in the same xhtml file.
The chooseGroupListener looks like this:
/**
* Is executed when a user hits the group hyperlink to select a group.
* Sets the selected group.
*/
public void chooseGroupListener(ActionEvent event)
{
System.err.println("--- PtGroGroup.chooseGroupListener() ---");
GroGroup o_Group = (GroGroup) Go_Table.getRowData();
o_Group.copyTo(this);
mUserInfo.setGroupId(getGroupId());
}
The Action is in another class and looks like this:
/**
* This Action is called when a user selects a group from the popup
search results.
*
* @return
*/
public String mainScreenAction() throws Exception
{
System.err.println("--- PtGroupAdmin.mainScreenAction() ---");
closePopup(); // close popup if it is open
return mMainScreen; // string of screen mapped in
faces-config-actions-common.xml (navigation case)
}
I am using on both classes where both methods are found. I
never see the println messages in the tomcat log window and the popup window
will not close because it never hits mainScreenAction() - although on the
first round through it works just fine. It's just that after the second
popup, it will not close again and I must exit the application.

RE: Finding a component with a specific id
Have you tried putting the colSelector after the datatable? It sounds
like the view does not yet contain the table. I thought myFaces had
similar issues with the DataScroller in ealier versions (maybe still
do). Maybe take a look on how they handled?
Of course, just a guess.
Good luck

Subject: Finding a component with a specific id
Hi,
From a custom renderer I need to be able to find a component with a
specific id.
Page:
..
From the renderer for the o:colSelector I've tried:
UIComponent table =
facesContext.getViewRoot().findComponent(tableId);
UIComponent table = component.findComponent(tableId);
UIComponent table = component.findComponent(":" + tableId); but had
no luck.
The table is enclosed in a subview named "body", so the id actually gets
output as "body:table1". I've tried all the above with that string too,
and no luck.
Any ideas how I should locate that table component by id??
[And BTW, is it possible for a component in a naming container to have
an id that is *not* prefixed by its NamingContainer parent's id?]
On a related note, looking at the source for UIComponent.findComponent,
I see it calls _ComponentUtils.findComponent which is as follows.
static UIComponent findComponent(UIComponent findBase, String id)
{
if (idsAreEqual(id,findBase))
{
return findBase;
}
for (Iterator it = findBase.getFacetsAndChildren();
it.hasNext(); )
{
UIComponent childOrFacet = (UIComponent)it.next();
if (!(childOrFacet instanceof NamingContainer))
{
UIComponent find = findComponent(childOrFacet, id);
if (find != null) return find;
}
else if (idsAreEqual(id,childOrFacet))
{
return childOrFacet;
}
}
return null;
}
What's the point of that "instanceof NamingContainer"? Why doesn't the
search recurse into NamingContainer children of findBase?
Thanks,
Simon
x:inputCalendar issue with August/September
Title: Message Looks like additional problems with x:inputCalendar. I have found that whenever a date for the months of August or September is selected, regardless of the year, subsequent visits do not show the calendar days and the current month is undefined. Has anyone else found this problem?

Rendering Not Correct on First Visit to Page
Title: Message Hello, I am attempting to dynamically render components on a page during first visit (using request-scope beans), specifically datatable components (rendering via value-binding), as well optionally addMessage for a h:message component. The datatable rendering appears to pick up the default rendering when bean first created. As well, any message added during processing is not displayed.Background:When page first accessed, I'm trying to build a datatable based on current dates. When there is no data, I'm attempting to display a message and not render the datatable. Tracing indicates that isRendered is false. However, the page is displayed with the Table rendered and no message displayed. I use x:Savestate (myFaces) for subsequent requests, so all is fine then.Can anyone help?Best Regards, Lisa Blue-in-the-Faces The electronic mail message you have received and any files transmitted with it are privileged & confidential and solely for the intended addressee(s)’s attention.
