Loop, RadioGroup and Coercion
Hello,
I'm trying to make a tapestry component that looks like a poll.
This component will contain a question, a list of suggestions, and a button
to vote.
I didn't want to use Ajax at first, and the click on the vote button will
reload the whole page for example.
The question and the list of suggestions were load from my database, and I
have no problem to display them correctly on my form.
If no radio button is selected, I can click on the vote button, it works.
The problem occurs when I'm trying to submit the form and when a radio
button is selected.
Here is the code of my .tml file :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd"
xmlns:p="tapestry:parameter">
<t:form t:id="survey_form">
<h4>${formSurvey.category.label}</h4>
<h5>${formSurvey.startDate}</h5>
<p id="surveyLabel">${formSurvey.label}</p>
<t:radiogroup t:id="suggestionRG"
value="selectedSuggestion">
<t:loop source="suggestions" value="suggestionLoopValue"
encoder="suggestionEncoder">
<t:radio t:id="radio" value="suggestionLoopValue"/>
<t:label
for="radio">${suggestionLoopValue.label}</t:label>
</t:loop>
</t:radiogroup>
<t:submit id="surveyVote" t:id="vote"
image="context:images/vote_button.gif" />
</t:form>
</t:container>
And here is the code of my java file :
@SuppressWarnings("unused")
public class Survey {
@Parameter(required=true)
private int surveyId;
@Property
@Persist("SESSION")
private com.titans.surveys.model.Survey formSurvey;
@Inject
private ISurveyManager mSurveyManager;
@Persist
@Property
private Suggestion selectedSuggestion;
@Property
private Suggestion suggestionLoopValue;
@Property
@Persist
private List<Suggestion> suggestions;
@Property
private ValueEncoder<Suggestion> suggestionEncoder = new
ValueEncoder<Suggestion> () {
public String toClient (Suggestion pSuggestion) {
return (String.valueOf (suggestions.indexOf (pSuggestion)));
}
public Suggestion toValue (String pId) {
return (suggestions.get (Integer.parseInt (pId)));
}
};
public void beginRender() {
this.formSurvey = mSurveyManager.findById(surveyId);
if (this.formSurvey == null) {
sLogger.error("Unable to retrieve survey with id = " + surveyId);
}
else {
if ((this.suggestions == null) ||this.suggestions.isEmpty())
this.suggestions = new
ArrayList<Suggestion>(formSurvey.getSuggestions());
}
}
}
Here is the ComponentEventException throwed :

Could someone know what I'm doing wrong ?

Re: Loop, RadioGroup and Coercion
Posted by antb59 <an...@gmail.com>.
Hi again,
In fact, I have a correct behavior for the display of the forms when I used
formState="NONE" in the loop inside form.
But the problem is on the parameter "action" of the form that contains the
loop on suggestions.
Here is the HTML code generated when I fix the surveyId value on the first
Loop :
<form id="survey_form_5" name="survey_form_5" method="post"
action="index.surveysuggestionsform_0.survey_form"
onsubmit="javascript:Tapestry.waitForPage(event);">
Here is the HTML code generated when I iterate on surveys :
<form id="survey_form_4" name="survey_form_4" method="post"
action="index.surveysuggestionsform.survey_form"
onsubmit="javascript:Tapestry.waitForPage(event);">
</form>
The problem seems to be on "index.surveysuggestionsform.survey_form"
Which modification I have to do in order to have dynamic "action" parameters
for the loop of forms ?
I want the "action" parameter to be
"index.surveysuggestionsform_0.survey_form"
"index.surveysuggestionsform_1.survey_form"
"index.surveysuggestionsform_2.survey_form"
when I use the component in the following loop :
<t:loop source="surveys" value="surveyLoopValue" encoder="surveyEncoder">
<t:surveys.surveySuggestionsForm surveyId="surveyLoopValue.id" />
</t:loop>
Regards,
Antoine.

Re: Loop, RadioGroup and Coercion
Posted by antb59 <an...@gmail.com>.
After reading the documentation for LoopFormState, I found that ITERATION is
the value I want in my case.
"When the Form is submitted, the Loop will re-acquire its source and iterate
over it"
But when I used this value in my loop component, an new error is throwed :

Am I missing something ???

Yes, because everytime you use an expansion to value is transformed in a
String.

The ones inside Forms, I guess.

Thanks for your fast answer !
When you say "never use expansions in
component parameters", you mean this syntax
<t:surveys.surveySuggestionsForm surveyId="surveyLoopValue.id" />
is better ?
About the LoopFormState, I'm going to check this feature, I didn't know
it...
Do I have to change the LoopFormState of the loop of forms or the loop of
radio buttons ?
regards,
Antoine.

It probably isn't the source of your problem, but never use expansions in
component parameters.

Try using some value of Loop's formState parameter.

Re: Loop, RadioGroup and Coercion
Posted by antb59 <an...@gmail.com>.
Hello again,
I have a new problem related to this loop of radio buttons :
I want to make a list of forms, with each form containing a list of radio
buttons.
I can easily do that in a "static" way, with an index.tml file containing
the following lines :
...
<t:surveys.surveySuggestionsForm surveyId="1" />
<t:surveys.surveySuggestionsForm surveyId="2" />
<t:surveys.surveySuggestionsForm surveyId="3" />
...
And the SurveySuggestionsForm.tml :
<t:form t:id="survey_form">
<t:radiogroup t:id="suggestionRG" value="selectedSuggestion"
encoder="suggestionEncoder">
<t:loop source="suggestions" value="suggestionLoopValue"
encoder="suggestionEncoder">
<t:radio t:id="radio" value="suggestionLoopValue"/>
<t:label for="radio">${suggestionLoopValue.label}</t:label>
</t:loop>
</t:radiogroup>
<t:submit id="surveyVote" t:id="vote" t:mixins="confirm"
image="context:images/vote_button.gif" />
</t:form>
Here is the code of SurveySuggestionsForm.java
public class SurveySuggestionsForm {
private static final Logger sLogger = Logger.getLogger
(SurveyResults.class);
@Parameter(required=true)
private int surveyId;
@Inject
private ApplicationStateManager applicationStateManager;
@Inject
private ISurveyManager mSurveyManager;
@Property(write=false)
@Persist
private User userInSession;
@Property
@Persist("SESSION")
private com.titans.surveys.model.Survey survey;
@Persist
@Property
private Suggestion selectedSuggestion;
@SuppressWarnings("unused")
@Property
private Suggestion suggestionLoopValue;
@Property
@Persist
private List<Suggestion> suggestions;
@SuppressWarnings("unused")
@Property
private ValueEncoder<Suggestion> suggestionEncoder = new
ValueEncoder<Suggestion> () {
public String toClient (Suggestion pSuggestion) {
return (String.valueOf (suggestions.indexOf (pSuggestion)));
}
public Suggestion toValue (String pId) {
return (suggestions.get (Integer.parseInt (pId)));
}
};
public void beginRender() {
this.survey = mSurveyManager.findById(surveyId);
if (this.survey == null) {
sLogger.error("Survey in parameter is null");
}
else {
userInSession =
applicationStateManager.get(SessionContent.class).getUser();
this.suggestions = new ArrayList<Suggestion>(survey.getSuggestions());
}
}
public String onSuccess () {
boolean resultOfVote = mSurveyManager.vote(survey, userInSession,
selectedSuggestion);
return null;
}
public boolean isSurveyNotNull() {
return (survey != null);
}
public boolean isUserLoggedIn() {
return (userInSession != null);
}
}
The problem is when the surveyId in parameter of the surveySuggestionsForm
component is filled in a dynamic way :
<t:loop source="surveys" value="surveyLoopValue" encoder="surveyEncoder">
<t:surveys.surveySuggestionsForm surveyId="${surveyLoopValue.id}" />
</t:loop>
In this case, when a form is submited, the related surveySuggestionsForm
didn't seem to receive the correct value for the list named "suggestions",
and an exception is throwed :

Re: Loop, RadioGroup and Coercion
Posted by antb59 <an...@gmail.com>.
Thanks for you fast answer Christophe !
Here is the new code for my radioGroup :
<t:radiogroup t:id="suggestionRG" value="selectedSuggestion"
encoder="suggestionEncoder">
<t:loop source="suggestions" value="suggestionLoopValue"
encoder="suggestionEncoder">
<t:radio t:id="radio" value="suggestionLoopValue"/>
<t:label for="radio">${suggestionLoopValue.label}</t:label>
</t:loop>
</t:radiogroup>
It works!
Many thanks.
