Hi folks,
I've a web application which uses Seam 1.0 beta 2 on a JBoss AS 4.0.4 RC1 with
Facelets (from the booking demo) and myFaces 1.1.1.
I've a session scoped component with a member: currentTestaction
(@In(required=false) @Out(required=false). The member's attributes are
displayed in a form. Some of them are editable (inputText) and are simple
Strings, so I didn't append a converter. If the user hits the "save" button his
changes should be saved.
After hitting the save button, the 'Restore view' and the 'Apply request
values' phases do their job. After these phases there is a viewRoot, which has
all the entered information. The next phase, 'Process validations', tries to
validate all the entered information. Because I didn't append a converter
myFaces tries to determine the type (ValueBinding.getType()). But then there is
a PropertyNotFoundException thrown: "Target Unreachable, identifier
'currentTestaction' resolved to null".
Has anybody an idea, why 'currentTestaction' cannot be resolved?
Here's the code of the component:
@Stateful
| @Scope(ScopeType.SESSION)
| @LoggedIn
| @Name("testactionDeveloper")
| @Interceptors(SeamInterceptor.class)

| return "backToList";
| }
|

| if(shiftTestaction(-1)) {
| return "browse";
| }
| return "backToList";
| }
|

| }
|

| if(currentTestactions == null ) {
| return 0;
| }
| return currentTestactions.size();
| }
|
| public String getDeveloperReleaseHR() {
| if(currentTestaction == null ) {
| return "devrelease";
| }
| List<Release> release = em.createQuery(
| "from Release where REL_ID=:relID order by
REL_ID asc"
| ).setParameter("relID",
currentTestaction.getDevRelID()).getResultList();
| String result = "release not found";
| if(release.size() > 0) {
| result = release.get(0).getRelToken();
| }
| return result;
| }
|
| @Remove @Destroy
| public void destroy() {
| }
|
| private boolean shiftTestaction(int distance) {
| if(currentTestactions.size() == 0) {
| return false;
| }
| currentTestactionIndex += distance;
| while(currentTestactionIndex >= currentTestactions.size()) {
| currentTestactionIndex -= currentTestactions.size();
| }
| while(currentTestactionIndex < 0) {
| currentTestactionIndex += currentTestactions.size();
| }
| currentTestaction =
currentTestactions.get(currentTestactionIndex);
| return true;
| }
