[JBoss Seam] - Re: Can't find Stateful Bean...
by pdpantages
Hello Peter, thank you for your response.
Unfortunately, Seam component serviceEndPointMgmt does not exist in the parent conversation prior to invoking the editor (which in turn causes the exception). I can verify the absence of this object with the seam debugger. It is supposed to be created only when the editor is launched.
Thus, I don't quite understand the log message about finding it in the conversation; I assumed that this is just a side-effect of using @In(create=true). I will stick some traces in the ctor and @Create method and see if I can find anything.
So, the upshot is, I don't quite understand how I can periodically touch it. Normally, this would be easy to do, as my page has an ajax poll every 4s...
Could I avoid the problem by declaring the injected object transient? I have never tried this on a seam component.
Thanks PdP

[JBoss Seam] - Re: howto display the an enum object internationalized
by lcoetzee
What we do is the following:
| public enum GenderEnum {
| FEMALE, MALE;
|
| public final static String translatedGenders[][] = {
| {"Female", "Male"},
| {"Vroulik", "Manlik"},
| {"Female - Zulu", "Male -Zulu"},
| {"Female - ndebele", "Male - ndebele"},
| {"Female - xhosa", "Male - xhosa"},
| {"Female - sotho", "Male - sotho"},
| {"Mosadi", "Monna"},
| {"Female - setswana", "Male - setswana"},
| {"Female - siswati", "Male - siswati"},
| {"Female - venda", "Male - venda"},
| {"Female - songa", "Male - songa"} };
| }
|
|
Which is then accessed (in Java or JSF)
| GenderEnum.translatedGenders[userEnvironment.getLanguage().ordinal()]
| [GenderEnum.MALE.ordinal()]
If you want to get a specific translation for a specific enum.
Regards
Louis
