xpages save / cancel actions scenario - xpages

Question

I will describe shortly my little project application:
the main doc. content is Cdoc ( datasource which contains fields + a button ). This button displays a dialog which is Pdoc ( a datasource ) - before showing the button I will save the doc. to get the UNID and then I will pass it to the Pdoc, I want to link the Cdoc and Pdoc with the UNID.
My button which shows the dialog:
<xp:button value="Adding Pdoc from the dialog" id="button3"
styleClass="lotusFormButton" refreshMode="partial">
<xp:eventHandler event="onclick" submit="true"
refreshMode="partial" refreshId="computedField3">
<xp:this.action><![CDATA[#{javascript: if ( Cdoc.isNewNote() ) { Cdoc.save(); }
Cdoc.setValue("computedField3",Cdoc.getDocument().getUniversalID());
getComponent('exampleDialog').show()}]]></xp:this.action>
</xp:eventHandler>
The dialog / Pdoc contains just 1 button: Save ( because the X button is implicitly added to the dialog )
<xp:button value="Salvare" id="button6" styleClass="lotusFormButton">
<xp:eventHandler event="onclick"
submit="true" refreshMode="partial" immediate="false"
save="false" refreshId="viewPanel1">
<xp:this.action><![CDATA[#{javascript:Pdoc.save();
getComponent('exampleDialog').hide();
}]]>
</xp:this.action>
</xp:eventHandler>
So, it saves the docs. from Pdoc and they are displayed in an embedded view from Cdoc.
The main. doc Cdoc contains also 2 (actions) buttons:
Cancel: redirect to Previous Page.
and
Save
<xp:button value="Salvare" id="buttonSave" styleClass="lotusFormButton" rendered="#{javascript:currentDocument.isEditable()}">
<xp:eventHandler event="onclick" submit="true"
refreshMode="partial" immediate="false" save="true"
id="eventHandler1">
<xp:this.action><![CDATA[#{javascript:if (Cdoc.getItemValueString("txt_UNID")!= "") {
Cdoc.save();
}
facesContext.getExternalContext().redirect("http://ourserver.ro/XApp.nsf/view.xsp")
}]]></xp:this.action>
</xp:eventHandler>
</xp:button>
The problem is:
Let say I'll create 3 docs. from Pdoc from the dialog, the Cdoc. is already saved ( because the UNID was obtained ). If I save then using Cdoc Save, my main view panel from view.xsp will display:
one doc. Cdoc with its 3 Pdoc docs. ( I need just this case to be displayed )
another Cdoc ( I guess when I first obtain the UNID and I saved the Cdoc to obtain the UNID, this is the Cdoc in this case. Btw, if I save again Cdoc using the Save button , will the UNID will change ? ) and one empty ( don't know why ) Pdoc from the dialog.
How should my Save button from Cdoc should be like? Should I change also the Save from Pdoc button?
Thanks for your time.

Answer 1

I believe save="true" on a button will submit and save all datasources on the page. That could explain spurious Pdoc documents. You're calling the save in script, so you don't need save="true" - you can just use a normal Button type rather than Submit type for the button.
Once a Document has been saved, the UNID will not be changed.
