Hi, The problem was apparently a conflict between two jquery instances. Starting from Tapestry 5.4 , Tapestry includes jQuery by default. Remove my own defined jQuery instance fixed the problem.

You can provide an id yourself to avoid problems, but I don't think that's
related to the problem.
For what I have seen, is the event link id getting changed.
Any help is appreciated.
t:context="${currentIndex}" >
Never, never, never ever use ${} expansions to bind parameters. It's wrong

public Object onBalExpand(String currentIndex) {
return balZone;
}
Never return a zone instance directly: return zone.getBody(). That's
probably the source of your problem.

RE: NullPointer when refreshing a page with a table inside a zone
Thanks for all your answers.
I tried your solution Thiago like this:
BeanModel getModel() {
return
beanModelSource.createDisplayModel(myObject.class,resources.getMessages());
}
And by removing:
@Property
private BeanModel< MyObject > model;
But then I get: ...pages.Index does not contain a property (or public field)
named 'model'
The solution I found was to define my model two times:
@BeginRender
public void begin() {
model = beanModelSource.createDisplayModel(myObject.class,
resources.getMessages());
}
And in
@OnEvent(value="success", component = " myForm ")
public void processForm() throws Exception {
myObjects = ...
model =
beanModelSource.createDisplayModel(myObject.class, resources.getMessages());
...
ajaxResponseRenderer.addRender("myZone ", myZone.getBody());
}
I guess it's not really clean to define it two times...
I m using Tapestry version 5.3.3
Thx
Christophe

Your code is missing that part that provides the value for myObjects and what
Tapestry version you're using. In addition, you seem to be only setting the
model field when rendering the whole Grid. Why don't you remove the model field
and replace it with this:
BeanModel getModel() {
return
beanModelSource.createDisplayModel(myObject.class,resources.getMessages());
}
This will make sure the model passed to Grid is never null.

NullPointer when refreshing a page with a table inside a zone
Hi,
I have the following zone with table inside :
...
There is nothing
And the following form :
After updating the zone using ajax like this:
@Property
private BeanModel model;
@Inject
private BeanModelSource beanModelSource;
@OnEvent(value="success", component = " myForm ")
public void processForm() throws Exception {
model =
beanModelSource.createDisplayModel(myObject.class, resources.getMessages());
...
ajaxResponseRenderer.addRender("myZone ", myZone.getBody());
}
My zone get updated and the table become visible.
But I get a Null pointer if I refresh the page or when a redirection is done on
this page:
Caused by: java.lang.NullPointerException
at
org.apache.tapestry5.corelib.components.GridColumns.setupRender(GridColumns.java:112)
at
org.apache.tapestry5.corelib.components.GridColumns.setupRender(GridColumns.java)
at

at
org.apache.tapestry5.internal.structure.ComponentPageElementImpl$AbstractPhase.invoke(ComponentPageElementImpl.java:133)
What am I doing wrong?
(Also I have the feeling the page is not fully reloaded when the page is
refreshed!?)
Thx

Re: AJAX updating table row
each ajax request is still a new request and therefore properties in
your page class are lost from the previous render.
unless you mark them as @Persist.
but in your case, your `service` property is set by the loop component.
this is not going to be "emmulated" by the ajax request processing since
you are just updating the 'insides' of one iteration of the loop.
you will need to use your context parameters or some other mechanism to
set your "service" value for each subsequent ajax request.

. I've modified some code to fit my use case. I have a table that uses a
t:loop to iterate through services and show if they are activated. I then
have eventlinks to activate/deactivate services. My server code writes to a
database based on the eventlink clicked. Here are parts of the code (dunno
how to post html):
<(tr) t:type = "Zone" t:id = "rowZone" id = "currentRowZoneId" t:update =

<(a) t:type = "eventlink" t:event = "deactivate" t:context =
"service.serviceID" t:zone = "^" href = "#">Deactivate<(/a)>
My java:
private List services;
@InjectComponent
private Zone rowZone;
@Inject
private Request request;
@Inject
private AjaxResponseRenderer ajaxResponseRenderer;
@Property
private Service service;
void setupRender() {
services = getServices();

userServiceDao.delete(us.getUserserviceID());
if (request.isXHR()) {
ajaxResponseRenderer.addRender(rowZone);
}
}
public String getCurrentRowZoneId() {
return "rowZone_" + service.getServiceID();
}
So when the eventlink is clicked, the onDeactivate() method gets called with
serviceID as context. This removes the userservice from the db and calls
addRender() on the rowZone. I immediately get this error:
Render queue error in Expansion[PropBinding[expansion
service/ActivationAjax(service.name)]]: Property 'service' (within property

Since ajax is only making the specific row to update, we aren't looping
again so how does it know which service (thus NPE)? In the tutorial I posted
above, it works fine. Any ideas?

Re: Render whole table grid row as a link?
I've just written a GridDecorator mixin that allows you to decorate rows or cells in a grid. The code can be found here: https://github.com/uklance/tapestry-stitch/blob/master/src/main/java/org/lazan/t5/stitch/mixins/GridDecorator.java A demo can be found here with examples for RowDecorator and CellDecorator: https://github.com/uklance/tapestry-stitch-demo/blob/master/src/main/java/org/lazan/t5/stitch/demo/pages/GridDecoratorDemo.java https://github.com/uklance/tapestry-stitch-demo/blob/master/src/main/resources/org/lazan/t5/stitch/demo/pages/GridDecoratorDemo.tml Cheers, Lance. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Render-whole-table-grid-row-as-a-link-tp5717388p5717913.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Render whole table grid row as a link?
Well, I'm sure you're a smart guy and can figure out how to get the tbody.
The mixin will fire after the grid component has rendered. The grid renders
a table inside a div so you will need to do something like:
List topChildren = writer.getElement().getChildren();
Element div = (Element) topChildren.get(topChildren.size() - 1);
Element tbody = div.find("table/tbody");

Re: Shorten CSS selector styles for table grid?
You can use a richer language like LESS or SASS to write e. g.:
.a {
color: red;
.b {
font-weight: bold;
}
.c {
height: 1px;
}
}
instead of
.a {
c: r;
}
.a .b {
f-w: b;
}
.a .c {
h: 1px;
}

Re: Shorten CSS selector styles for table grid?
This is a pure CSS question, so it's off-topic here. This is actually a mailing list, not a forum (Nabble is just a forum interface for the mailing list, and a good one), so we, subscribers of the Tapestry users mailing list, we want to receive in our e-mail inboxes messages that are about Tapestry in some way of another, and this question isn't about Tapestry at all. It's about CSS selectors and nothing else. I know you're getting tired of reading me asking people to avoid off-topic questions, but they keep coming and I don't want to see people unsubscribing to this list because of that. -- Thiago H. de Paula Figueiredo - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Shorten CSS selector styles for table grid?
I want to style serveral grid columns differently. How can I shorten these
expressions?
I always need the prefix "table.t-data-grid thead tr th.", followed by the
specific property. Can't I just specify that prefix and after list all
property classes that shoud be matched?
Or do I always have to write the full selector statement like:
table.t-data-grid thead tr th.depot, table.t-data-grid thead tr th.amount
... {
}
Thanks

Re: Render whole table grid row as a link?
This might be best handled by a mixin to the grid. The mixin would: 1. Add an id to each row in the html table markup 2. Generate an event URL for each row using ComponentResources.createEventLink(); 3. Attach an observer to each row (using the row id) which listens to the "click" event and fires the event URL. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Render-whole-table-grid-row-as-a-link-tp5717388p5717393.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Render whole table grid row as a link?
Hi, is it possible to just make a whole row of a table grid clickable? I know how to apply a t:pagelink to the text of a specific entry. But for this the link is only executed if I click on the text directly. How can I just click somewhere on that row? Or is this ever possible?

Re: Table with custom columns?
t:table component? You probably mean a Grid component
(http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/corelib/components/Grid.html)
And to add a custom row is like this:
${totalqty}
In your page class there should be a method called getTotalqty().
@Property
private List products;
@Property
private Product product;
private double totalqty;
public double getTotalqty(){
return product.price * product.quantity;
}

I do not understand what you are trying to achieve

elements inside outputraw within a template. Use output raw to stream html from
your page class, for example assume you have a preformated product description

In java page
public String getProductDescription() {

Re: cannot output table tags in outputraw compnnent
The following works.
In .tml:
${myTag}
In .java :
public String getMyTag(){
return "";
}
Alternatively, you could put your tag in the .properties file :
${message:myTag}
.properties:
myTag=

Please post the generated HTML. As Pavel noted, the Loop component doesn't
have an include component. Are you sure you aren't using Grid instead of
Loop?
[written before I noticed the template snippet above didn't use Grid]
Grid will always render as a table. After all, its name is 'Grid' and
grids are two-dimensional things, while lists are one-dimensional. As
Pavel suggested, you can use a Loop instead and render whatever you want.

Re: How to avoid ul turning into table?
You should use
http://tapestry.apache.org/5.3/apidocs/org/apache/tapestry5/corelib/components/Loop.htmlwhich
works similar to Grid but does not imply rows or cells. Your source
and value parameters are still correct, and you no longer need the include
parameter.

Re: Possible to build a Table from multiple sources?
With all distractions I have right now I haven't had a lot of time to finish my table, but I got back to it and followed advise from you guys and a similar example to my own which seems very straight forward. I'm following the 'Grid row highlighter demo<http://lombok.demon.co.uk/tapestry5Demo/test/mixins/gridrowhighlighterdemo>' by Shing Hing Man to construct my table with a few ommissions (don't need cell highlighting for example), however, on creating my beanmodel (which has only getMethods and setMethods and the respective instance members when I try to execute/run my project I get the following exceptions: java.lang.RuntimeException Exception assembling root component of page LeaderboardPage: Unable to instantiate instance of transformed class com.sony.otg.c3demoapp.pages.DoStuffPage: java.lang.reflect.InvocationTargetException which is caused by: java.lang.reflect.InvocationTargetExceptiontargetExceptionorg.apache.tapestry5.ioc.internal.OperationException: Unable to create new accessor method public int getPosition() on class com.sony.otg.c3demoapp.pages.DoStuff as the method is already implemented. I read somewhere that Tapestry will create get/set methods that are not present but since I have provided them why do I get this error? Commenting them out is not an option because in my class Decode (which parses my Json input) I call setMethodName (and getMethodName) for each of the items I retrieve from the Json object. I would also have to omit the getMethods as well and this would leave my beanmodel pretty empty and I don't see what I'm doing wrong. If I compare this example with the 'Grid' example on jumpstart then I see that the @Entity annotation is being used along with 'implements Serializeable'. The 'Grid row demo' doesn't use either of these and so I'm a bit confused as to which is the 'correct' way to go. So my questions are: 1 - Why does Tapestry complain if I implement getMethodName/setMethodName ? 2 - Should I Serialize my class and annotate it with @Entity? 3 - Both of the two examples create a table/grid when the page loads using pageLoaded() or setupRender() calls, but I only want a table generated onClick from a link I have on the page. Is it good practice to do this using an Event Link that will then render my table on the same page? Again, thanks for any responses/support from the Tapestry Users.

Re: Possible to build a Table from multiple sources?
If I understand correctly, you read your data into multiple lists. To read a single record, you use the same index in each list... Correct? This sort of model often leads to a maintenance nightmare. Create a bean which represents a single row in the grid and read your data into a single list. You'll thank me in the future ;)
Re: Possible to build a Table from multiple sources?
I want simply to display data in tabular format with 3 or more headers,
currently I'm just experimenting with the three in my tml file (Position,
UUID, Result) and I may want to add an Id column (assigned or auto) as the
first column, similar to the Loop example on
http://jumpstart.doublenegative.com.au (it's currently reporting a 503 so I
can't give you the exact link).

Possible to build a Table from multiple sources?
Hi guys,
I'm trying to construct a table (Tapestry 5) unsuccessfully so far, and
have been scouring the forums (Nabble) and elswhere for examples on
building a table. So far it appears that it's only possible using a single
source (is that the only way?) either for a Loop, or Grid as demonstrated
on Jumpstart (I'm not using EJB).
The data I want to display has come from a Json object which I've
decoded/parsed and have used Jackson Tree structure to read the data and it
contains elements that I've read into Lists of either String, Integer and
Long as follows:
package com.blah.blah.blah.services;
@Entity
public class Decode implements Serializable{
private DefaultHttpClient httpClient = new DefaultHttpClient();
private final static ObjectMapper mapper = new ObjectMapper();
@Column
private List position;
@Column
private List uuid;
public void setPosition(List positionList) {
this.position = positionList;
}
public List getPosition() {
return position;
}
public List getUuid(){
return uuid;
}
public void setUuid(List uuid){
this.uuid = uuid;
}
public URL parseJson(String url){
...
...Http stuff here
...
try{
...
...I/O stuff here
...
JsonNode root = fileNode.get("items");
Iterator i = root.iterator();
while (i.hasNext()) {
JsonNode element = i.next();
// get the elements
int position = element.get("position").asInt();
String uuid = element.get("entrant").get("id").asText();
...
List positionList = new ArrayList();
positionList.add(position);
setPosition(positionList);
List uuidList = new ArrayList();
uuidList.add(uuid);
setUuid(uuidList);
System.out.println("position: " + position + ", uuid" +
uuid);

Following the examples on 'jumpstart' is really helpful but I've hit a
brick wall with this since I'm not using EJB (why such a complicated
example) and also my data from a json object is retireved as either String,
Integer or Long and so on and therefore I end up with multiple List
objects which all can be sources.
Can I use these all as I've done because if I try to retireve all my data
as List objects (I have tried this) then I'll get other problems
such as Coercion Exceptions or othere errors that I don't know what they
mean (I should have posted them here but it would make this post horrible
to read) but as it stands right now the System.out prints exactly what I
expect but I get no table being rendered. I only have one head so please
can someone stop me from bashing it in any more than I have done?
Oh and just to clarify (if not already clear) my Json object can and will
possibly contain hundreds of records from which I will need to parse and
extract the same data types (String, Long, Integer etc) over and over and
although they can be read as Strings that's not what their type is.
Thanks in advance for any assistance/replies

Re: how to get the index in tapestry loop and change background color of a table
1. use the 'index' attribute of loop:
2. add the indexProp to your page class
@Property private int indexProp;
3. use a property symbol for the appropriate style attribute (i'm
assuming the )
4. implement the logic in your page class
public String getAlternateColour()
{
return indexProp % 2 == 0 ? "#CDCECC" : "#FF";
}
5. enjoy.

When you use the add parameter, Grid doesn't know what the associated
value is for the columns you're adding. One way is providing a BeanModel
to the model parameter and adding columns through
beanModel.add("truck.id"), for example. Another way is to change your
TruckWoodPrice to have, for example, a getTruckId() { return
truck.getid(); } method.

Re: t5: create a record from another table, what is best practice?
Hi
onActivate() is called each time a page is loaded. So if you have a form on
a page, onActivate() will be called on both at the time of rendering and
submit/action phase
So if you have to initialize any variables before showing them in a form do
it in prepareForRender event of the form and if you want to do some thing
after submiting the form do it in prepareForSubmit event of the form. If you
want to do something common in both phases do it in prepare event of the
form.
Please refer to
http://tapestry.apache.org/tapestry5.2-dev/tapestry-core/ref/org/apache/tapestry5/corelib/components/Form.html

Re: Update table column via Zone(s)
Thanks, guys, both approaches works.
I went with Renderable, because wanted to render some other markup, not only
text.
Quick question to Cezary:
- why are you updating class fileds withing separate RenderCommand? Any
pitfalls?
In my experiments rendering and updating class state is working fine withing
one class, like this:
private RenderCommand cellZoneRenderer(final POS pos, final Contract cnt)
{
return new RenderCommand()
{
public void render(MarkupWriter writer, RenderQueue queue)
{
//update state
contract=cnt;
pointofsale=pos;
//render zone
((RenderCommand) visitsZone.getBody()).render(writer,queue);
}
};
}

A similar question was asked a couple weeks ago. You can search the
list for it for more details (subject was "Context of a Zone").
If what you are rendering is simple text then you can simply create
your MultiZoneUpdate in a loop. Here's what Mark came up with:
MultiZoneUpdate update = new MultiZoneUpdate("totalPriceZone",
totalPriceZone);
for (Item aitem : getItems()) {
update = update.add("priceZone-" + aItem.getId(),
getTotalPriceForItem(aItem)); <-- important part
}
return update;

Re: Update table column via Zone(s)
Hi Dmitriy,
I solved similar problem by chaining list of MultiZoneUpdate, each with its
own RenderCommand, something like that:
@Inject
private Block myBlock;
MultiZoneUpdate mzu = null;
for(String id : indexes) {
mzu = addMZU(mzu, "zone-" + id, prepareRender(id));
}
private RenderCommand prepareRendering(final String id) {
return new RenderCommand() {
@Override
public void render(MarkupWriter writer, RenderQueue queue) {
((RenderCommand)myBlock).render(writer, queue);
queue.push(new RenderCommand() {
@Override
public void render(MarkupWriter writer, RenderQueue
queue) {
currentId = id;
}
});
}
};
}
in .tml, I have:
Here rendering based on ${currentId}
I can not guarantee that it is the simplest way, but it works for me.

Cezary

Update table column via Zone(s)
Hi all,
i'm looking for some ideas how to update entire column in html table,
without updating overall table.
For instance:
${rowValue.a}
${rowValue.b}
${rowValue.c}
${some rowValue derived text or other
components}
on some event i want to update all zones with t:id="myZone". The issue is
that with XHR request t:loop is not executed and rowValue property is not
bound.
So even if i return properly populated MultiZoneUpdate it is rendered
incorrectly, because rowValue is not changed before invocations.
Any ideas how i can force t:loop to be executed or force myZone body to be
rendered (i can re-iterate collection myself in handler method)?
Thanks.
Re: Alternating table rows
For alternating rows you can try CSS :nth-child(N) pseudoclass (google for
details).
<http://reference.sitepoint.com/css/pseudoclass-nthchild>Here's quick
example:
.rowClass:hover, .rowClass:nth-child(even):hover {
background-color: #DCE5FF;
}
.rowClass:nth-child(even) {
background-color: #E8E8E8;
}

Hi, guys!
I was also frustrated about the simplicity of the template language at
the start.
Me too. But then I discovered that templates should have the least logic
on them, so it's way easier to test and to get the code right. If someone
really wants to put logic in template, use the OGNL binding from
ChenilleKit, but please, don't do that.
You can't (or couldn't even) negate a test!
You can negate a test with !: public
boolean isLoggedIn() {...}

Re: Alternating table rows
This alternating stripes effect is such a common need that I think it should
be a built-in capability of all of the looping components, as a parameter in
which you pass the names of the CSS classes to alternatively apply. JSF does
this, and it's very handy. I guess you could do this yourself with a custom
loop component that accepts a "classes=odd,even" parameter, but it'd be nice
to not have to.

Re: Alternating table rows
Katia has some good advice, I am also a strong advocate for code separation,
which equates to extensibility and maintanability.
Your page class (pure Java) is intended to replace JSP or any expression
language, queries and any other business logic is better when moved into IoC
where it is injectable and reusable. Tapestry purposefully minimizes expression
language usage in pages because:
- Its hard (or near impossible) to test in templates
- It clutters the templates (error prone)
- Its better done in Java where you can debug it (that's reason enough for me)
- Its NOT clean code seperation
If you are doing any more than trivial conditional evaluation in templates then
it is not clean markup. Its also good to keep your templates and page classes
as minimalistic as possible so that your UI can become pluggable if ever
required.

Peter

Alternating table rows
Hello, I am new to Tapestry, but I am working on a project that uses it. The version is 5. I am trying to make a HTML table in which even rows have one class, and odd rows have another class. So far, I tried the following (I am showing just the code that matters): This causes an exception: "Could not convert '(index % 2 == 0) ? 'even' : 'odd'' into a component parameter binding: Error parsing property expression '(index % 2 == 0) ? 'even' : 'odd'': Unable to parse input at character position 8.". This causes an exception: "Block parameters are only allowed directly within component elements.". >From this page http://tapestry.apache.org/tapestry5/guide/propexp.html I can't find any examples of conditionals. How can I make the alternating rows?

Re: sql update of existing table
After the update, try calling commit. If you are using
HibernateSessionManager from
http://tapestry.apache.org/tapestry5.1/tapestry-hibernate/
call HibernateSessionManager.commit().

sql update of existing table
Hello.
I am using Tapestry 5.0.18 framework with Netbeans 6.8, MS Sqlexpress 2005
and using hibernate support for accessing database.
One page is crated for data input. Other one will display data from table.
Input is performed using t:beaneditform and display via t:grid. Whatever
data I enter, it will be successfuly stored in database. Grid component will
display it all. So, this basic part is functioning ok.
Main entity, Class Servis has 3 attributes : servisid, InvNo, Vendor and
Status.
Servisid is generated value:
@Id
@GeneratedValue
private Long servisid;
so it is incremented for every new row and is unique.
To store data after clicking on submit/update in beaneditform, I use the
following code:
@CommitAfter
public Object onSuccess(){
Servis temp = new Servis();
temp.setInvno(servis.getInvno());
temp.setVendor(servis.getVendor());
temp.setStatus(servis.getStatus());
session.save(temp);
return start;
}
I have customized grid component to display additional column which would be
used to change status attribute.
Tml file :
Set
TRUE
Java class. I use following method to display only rows with status = FALSE
public List getList() {
Criteria crit = getSession().createCriteria(Servis.class);
crit.add(Restrictions.eq("status", Status.FALSE));
return crit.list();
}
Now, I want to update value of status by clicking on Set TRUE in grid
component. I tried with several variants like this:
Object onActionFromChange(long id) {
SQLQuery query = getSession().createSQLQuery("UPDATE tblServis SET
status = 'TRUE' WHERE servisid = "+id);
query.executeUpdate();
return start;
}
It won't update table. I also get no exception. Clicking on Set TRUE will
drive me to start page. I tested and I definitely get appropriate id from
grid.
Can somebody suggest me what should I do to accomplish table update?
Thanks in advance.
