xhtml files in subdirectories
Hi there,
I'm implementing an administration interface to manage several entities. For every database table I created two pages: the first on, say languages.xhtml displays all available languages in a datatable. The user can add, edit or delete a language. To add or edit a language another page should be displayed which shows the details of this language in a form. As soon as the user wants to edit a language, a conversation is started which ends if the user cancels or saves this language.
Nothing new here ;)
Now I tried to put those two files in a subdirectory since I want to separate the administration interface from the user interface. So I created a subdirectory admin and saved those two files there. Every JSF tag which references a file (like h:graphicImage and so on) now use such an URL: /path/file; it works. Then I read about the basePath and used it for my CSS.
Here are those two pages:
languages.xhtml

public void destroy() {
}
}pages.xml
<page view-id="/admin/languages.xhtml"> <navigation> <rule if-outcome="add"> <redirect view-id="/admin/language.xhtml" /> </rule> <rule if-outcome="edit"> <redirect view-id="/admin/language.xhtml" /> </rule> </navigation> </page> <page view-id="/admin/language.xhtml"> <navigation> <rule if-outcome="cancel"> <end-conversation /> <redirect view-id="/admin/languages.xhtml" /> </rule> <rule if-outcome="saved"> <redirect view-id="/admin/languages.xhtml" /> </rule> </navigation> </page>
The problem now is that the conversation ends unexpectedly. The use case is as follows: The user clicks Add to add a new language. The language.xhtml shows with empty fields. The user enters a token (nothing else) and then clicks Save. Now the page should be redisplayed with some error messages and the already entered value.
The error messages are displayed correctly. But the fields are empty again, since the conversation ended.
And I don't know why it ended. As I told you before I have a several pairs of pages that are almost the same. And they work. The only difference is that they aren't stored in a subdirectory and that they refer to other database tables. But the structure is the same.
Thanks in advance
