Re: Loop, RadioGroup and Coercion
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 :

Could someone know what I'm doing wrong ? Maybe a problem with t:id or

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 :

Here is the code of my Survey.tml
<t:form t:id="survey_form">
<t:radiogroup t:id="suggestionRG" value="selectedSuggestion"
encoder="suggestionEncoder">
<t:loop source="suggestions" value="suggestionLoopValue"
formState="literal:ITERATION" 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>
This component was included into SuperComponent :
<t:loop source="surveys" value="surveyLoopValue" encoder="surveyEncoder">
<t:surveys.survey surveyId="surveyLoopValue.id" />
</t:loop>
Am I missing something ???
Regards,
Antoine.

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.
