RE: aui localized form: how to write/read localized content?

Solved. With this code I can use an aui:form to read/write localized content.

In service.xml I have

        <column name="field1" type="String" localized="true" />

In edit_foo.jsp I have

<aui:form
    action="<%= (javax.portlet.ActionURL)renderResponse.createActionURL() %>"
    name="fm1"
>
   
[snip]
    <aui:fieldset>
        <aui:input name="field1" localized="<%= true %>" />

[snip]

In MsbOnePortlet.java I have

[snip]    
protected void updateFoo(ActionRequest actionRequest) throws Exception {
        long fooId = ParamUtil.getLong(actionRequest, "fooId");

[snip]        
        Set<Locale> locales = LanguageUtil.getAvailableLocales();

        Map<Locale, String> field1Map = new HashMap<Locale, String>();
        for (Locale locale : locales) {
            String languageId = LocaleUtil.toLanguageId(locale);
            String x1 = "field1";
            String localeParameter = x1.concat(StringPool.UNDERLINE).concat(languageId);
            String y1 = ParamUtil.getString(actionRequest,localeParameter);
            field1Map.put(locale, y1);
        }
[snip]            
        foo.setField1Map(field1Map);

This create the field1 content:

<?xml version='1.0' encoding='UTF-8'?>
<root available-locales="en_US,it_IT," default-locale="en_US">
<Field1 language-id="en_US">f1 english</Field1>
<Field1 language-id="it_IT">f1 italiano</Field1>
</root>

This content is correctly interpretaded by aui:form which show the field content in all translated languages

[SOLVED] aui localized form: how to write/read localized content?

2018-09-07T11:32:29Z

Hi all,

I'm trying to develop an MVC portlet that manages localized content using Liferay 7.1 CE GA 1.

After many attempts (and many thread in this forum) I ended up with half solution: I'm able to use an aui:form to acquire localized content; but I cannot save the data in any form that is recognized by aui.

I mean:

in the browser in a field (field1) I enter english and italian translation
debugging the portlet for edit action I can see that the english and italian translation are there
I store the field as a map <Locale,String> converted to string
when I try to edit the record, the field1 content is the strored string assigned to the default language and the translation is lost

How can I write and read localized content so that aui:form is happy and show all translations?

TL;DR

This is what I have and what I attempted.

In service.xml I have

        <column name="field1" type="String" localized="true" />

In edit_foo.jsp I have

<aui:form
    action="<%= (javax.portlet.ActionURL)renderResponse.createActionURL() %>"
    name="fm1"
>
   
[snip]
    <aui:fieldset>
        <aui:input name="field1" localized="<%= true %>" />

[snip]

In the browser I typed two translation - see aui-field1.png attachment

You can see that en_US is the default language and that it_IT is translated (BTW when it_IT is selected under the input field the en_US translation is showed)

In MsbOnePortlet.java I have

[snip]

    protected void updateFoo(ActionRequest actionRequest) throws Exception {
        long fooId = ParamUtil.getLong(actionRequest, "fooId");

        boolean field2 = ParamUtil.getBoolean(actionRequest, "field2");
        int field3 = ParamUtil.getInteger(actionRequest, "field3");
        
        Set<Locale> locales = LanguageUtil.getAvailableLocales();

        Map<Locale, String> map1 = new HashMap<Locale, String>();
        for (Locale locale : locales) {
            String languageId = LocaleUtil.toLanguageId(locale);
            String x1 = "field1";
            String localeParameter = x1.concat(StringPool.UNDERLINE).concat(languageId);
            String y1 = ParamUtil.getString(actionRequest,localeParameter);
            map1.put(locale, y1);
        }        
        String field1 = map1.toString();
        System.out.println("mappato field1");
[snip]

Debugging this code I see that field1 contains

{es_ES=, it_IT=Campo 1 testo in italiano, fr_FR=, en_US=Field 1 english text, de_DE=}

See the map and the field in the debug-field1.png attachment

When I try to edit the the row, the edit_foo.jsp page shows the string as the default language translation and that there is no italian translation. See aui-field1-edit.png attachment

I tried also to see how the journal article was developed but I lost myself in the code (https://github.com/liferay/liferay-portal/tree/master/modules/apps/journal )

What I have to do?
