I think I have found the problem, but dunno why its happening..
I did the follwoing:
NSLog.out.appendln(status.status() + " " + workT.name()+ " "+
categ.name());
and a nullpointerException was raised... nothing of the above has
something all is null.. and ofcourse I can not make any relation with
null when mandatory in the EOModel.
Im binding those data as follow:
<div id ="statusDiv">
<span class = "labelDiv">Please Select a Status :</span><span
class="infoUnits">
<wo:WOPopUpButton list = "$statusList" selectedValue = "$status" id =
"status" item = "$theStatus" displayString = "$theStatus.status" /></
span>
</div>
<br />
<div class = "preTitle">Project's Work Type</div>
<div id = "statusDiv">
<span class = "labelDiv">Please Select a Work Type :</span><span
class="infoUnits">
<wo:WOPopUpButton list = "$workTypeL" selectedValue = "$workT" id =
"status" item = "$theWT" displayString = "$theWT.name" /></span>
</div>
<br />
<div class = "preTitle">Project's Category</div>
<div id = "statusDiv">
<span class = "labelDiv">Please Select the Category :</span><span
class="infoUnits">
<wo:WOPopUpButton list = "$catList" selectedValue = "$categ" id =
"status" item = "$theCat" displayString = "$theCat.name" /></span>
</div>
<br />
the list of the popupbuttons are being fetched as:
statusList =
PROJECT_STATUS
.fetchAllPROJECT_STATUSs(((Session)session()).defaultEditingContext());
workTypeL =
WORK_TYPE
.fetchAllWORK_TYPEs(((Session)session()).defaultEditingContext());
catList =
PROJECT_CATEGORY
.fetchAllPROJECT_CATEGORYs
(((Session)session()).defaultEditingContext());
the list in the popup are ok, but somehow the bindings are not
working...
Any clues.?

Hello I was able to save just the main data, without
relationships.. when I try to save 1 relation ship, it generates
no error, but at the same time there is no relationship made.. I
have done this:
PROJECT theProject = new PROJECT();
session().defaultEditingContext().insertObject(theProject);
theProject.setDescription(description);
theProject.setDue_date(dueDate);
theProject.setReceived_date(receivedDate);
//theProject.setINVOICE(null);
theProject.setName(name);
theProject.setPid(id);
theProject.setSpecial_notes(specialNotes);
theProject.setPROJECT_STATUSRelationship(status);
//theProject.addObjectToBothSidesOfRelationshipWithKey(status,
PROJECT.P_ROJEC_T_STATUS_KEY);
when savingChanges(), no relationship is save.. I mean I went and
check in the database, and I see in the fkcolumn that points to
the PROJECT_STATUS table, null. .. what am I doing wrong?
is ist something in the model?

I have the following code .. I commented the lines to check btu
still the same... sometimes this gives me a headache.. I checked
in another projects i did, and I fowllow as I did ther and
nothing..
public WOActionResults saveInfo() {
PROJECT theProject = new PROJECT();
session().defaultEditingContext().insertObject(theProject);
theProject.setDescription(description);
theProject.setDue_date(dueDate);
//theProject.setINVOICE(null);
theProject.setName(name);
theProject.setPid(id);
//theProject.setPROJECT_STATUSRelationship(status); //2nd
attempt
//theProject.addObjectToBothSidesOfRelationshipWithKey(status,
PROJECT.P_ROJEC_T_STATUS_KEY); // I try this first
//theProject.addObjectToBothSidesOfRelationshipWithKey(categ,
PROJECT.P_ROJEC_T_CATEGORY_KEY); // I try this first
//theProject.setPROJECT_CATEGORYRelationship(categ); //2nd
attempt
//theProject.setReceived_date(receivedDate);
//theProject.setSpecial_notes(specialNotes);
//theProject.setWORK_TYPE(workT);
//
theProject.addObjectToBothSidesOfRelationshipWithKey(workT(),
PROJECT.W_OR_K_TYPE_KEY);
//theProject.setWORK_TYPERelationship(workT); //2nd
attempt
//
theProject
.addObjectsToBothSidesOfRelationshipWithKey
(unitsList,PROJECT.U_NIT_S_OTHER_SS_KEY );
NSLog.out.appendln("HERE SO far so good");
((Session)session()).defaultEditingContext().saveChanges();
NSLog.out.appendln("the datawas sasved");
return null;
}
I attach a schema of my model... some things like names change
but the relationships are the same...
GRR!!!
Thanks for the help
