RE: Select with @InjectSelectionModel problem (value passed in is null)
Hi,
Thanks for your answer. I forgot to add the
public void onPrepare() and therefore the list was empty.
Thanks.
One addition for the tapestry wiki page.
I think it is better to replace:
String accessActualName = transformation.addField(Modifier.PRIVATE,
"org.apache.tapestry5.ioc.services.PropertyAccess", "_access");
into:
String accessActualName = transformation.addField(Modifier.PRIVATE,
PropertyAccess.class.getName(), "_access");
So we use no hardcoded package names.

RE: Select with @InjectSelectionModel problem (value passed in is null)
I have been debugging and noticed that the failure is in the
GenericValueEncoder.toValue method
The idFieldAdapter property is null and therefore it can't find a match.
And why is the idFieldAdapter null?
Because in the constructor(see below), the list parameter was null after
submitting the form.
Do I need to persist my List of objects? I don't want this
And I think the example on the wiki doesn't work as well.
Does anyone had this error earlier?
public GenericValueEncoder(List list, String idField, PropertyAccess access)
{
if (idField != null && !idField.equalsIgnoreCase("null")) {
if (list.size() > 0) {
this.idFieldAdapter =
access.getAdapter(list.get(0).getClass()).getPropertyAdapter(idField);
}
}
this.list = list;
}

Select with @InjectSelectionModel problem (value passed in is null)
Hello
I use the select component with the @InjectSelectionModel annotation as
described here:
http://wiki.apache.org/tapestry/Tapestry5AnotherSelectWithObjects
The select is nicely loaded with categories. Next I submit the form and I
notice that the setSelectedCategory method is called. But it prints
"setSelectedCategory: null"
See below for some the corresponding java code. What am I doing wrong? Why is
the selectedCategory null, after I have selected a category and submitted the
form?
@InjectSelectionModel(labelField = "name", idField = "id")
@Property
private List categories = new ArrayList();
@Persist
private Category selectedCategory;
public void setSelectedCategory(Category selectedCategory) {
System.out.println("setSelectedCategory: " + selectedCategory);
this.selectedCategory = selectedCategory;
}
public Category getSelectedRootCategory() {
return selectedRootCategory;
}

t5Components + Return JSONArray to component
I used the T5Components OnEvent. But for some reason I don't get the JSONArray
as a response in the javascript code.
I can see the javascript is called, but the response is "Undefined". I have no
clue what causes the problem. And am struggling with this issue for a couple of
days. I upgraded to tapestry 5.0.18. I had this working in an earlier version
of tapestry and t5components.
@OnEvent(component = "operator", value = "change")
public JSONArray onChangeOperatorEvent(String value) {
JSONArray jsonArray = new JSONArray();
for (Plaza plaza : getDestinationSelectValues(value)) {
JSONObject jsonObject = new JSONObject();
jsonObject.put("value", plaza.getId());
jsonObject.put("label", plaza.getDescription());
jsonArray.put(jsonObject);
}
return jsonArray;
}
Finally, the onCompleteOperatorChange javascript function has to parse the
return JSON and update the select input options:
function onCompleteOperatorChange(response) {
selectElement = $("entryPlaza");
responseJSON = response.evalJSON();
while (selectElement .options.length > 0) {
selectElement .options[0] = null;
}
for (index = 0; index < responseJSON .length; index++) {
selectElement.options[index] = new Option(responseJSON[index].label,
responseJSON [index].value);
}
Tapestry.ElementEffect.highlight($("entryPlaza"));
}
But the response is "Undefined" .

RE: [ANN] t5components 0.5.18 is now available for Tapestry 5.0.18
Yes I already tried that.
Also in debugging mode I can see that the AbstractEventMixin.onInternalEvent()
method returns a List with the JSONObjects.
Then the javascript code is called, but the response argument is "undefined"
I have no clue what causes this problem. I had this working in a previous
tapestry version.

RE: [ANN] t5components 0.5.18 is now available for Tapestry 5.0.18
Hi,
I use the @OnEvent mixin to create dependent selects:
I use it like below. But the problem is that the onCompleteOperatorChange
javascript function
response object is "undefined"
Any ideas how this is possible. The javascript function is called, but the
response is "undefined"
@OnEvent(component = "operator", value = "change")
public JSONArray onChangeOperatorEvent(String value) {
JSONArray jsonArray = new JSONArray();
for (Plaza plaza : getDestinationSelectValues(value)) {
JSONObject jsonObject = new JSONObject();
jsonObject.put("value", plaza.getId());
jsonObject.put("label", plaza.getDescription());
jsonArray.put(jsonObject);
}
return jsonArray;
}
Finally, the onCompleteOperatorChange javascript function has to parse the
return JSON and update the select input options:
function onCompleteOperatorChange(response) {
selectElement = $("entryPlaza");
responseJSON = response.evalJSON();
while (selectElement .options.length > 0) {
selectElement .options[0] = null;
}
for (index = 0; index < responseJSON .length; index++) {
selectElement.options[index] = new Option(responseJSON
[index].label, responseJSON [index].value);
}
Tapestry.ElementEffect.highlight($("entryPlaza"));
}
any help is welcome.

Usage of ApllicationState Object
Hello
I have a question about the usage of an ApplicationState object.
Can I use the @ApplicationState only in the com.application.tapestry.components
and com.application.tapestry.pages packages?
Or is it also valid in for example com.application.tapestry.beans package?
Because I have an ConversationManagerImpl class the isConversationsExists()
always returns false.
When I call conversationManager.startConversation(..) it prints false.
package com.application.tapestry.beans
public class ConversationManagerImpl implements ConversationManager {
@ApplicationState(create=false)
private Conversations conversations;
private boolean conversationsExists;
public boolean isConversationsExists() {
return conversationsExists;
}
public String startConversation(Object target) {
if(!conversationsExists) {
conversations = new Conversations();
}
System.out.println("conversation exists: " + isConversationsExists());
}
