xpages get UNID for a document/datasource - xpages

Question

I'm using Mark Hughes picklist on my xpage which is using a datasource. The view from which I pick the values is listing documents having another datasource.
I put the selected value into an <xp:inputText>. I do want to create a link which should redirect me to the listed document from the view ( from it I took the value ). In other words, I do want to find out the UNID of the document from the view, which I did selected it.
I tried the following code for the ssjsSelectFunction:
var unid = viewScope.unid;
if(typeof unid != "undefined" && unid != null)
{
var doc = database.getDocumentByUNID(unid);
var val1 = doc.getItemValueString("txt_numeAcord_1");
var val2 = doc.getUniversalID();
getComponent("inputText24").setValue(val1);
getComponent("inputText25").setValue(val2);
}
But after selecting the desired doc. from the picklist, only inputText25 is updated with the value ( UNID ), the inputText24 is empty. Only if I open again the picklist and select the doc., the inputText24 field value is added. I guess I'm missing something.
How can I achieve this?

Answer 1

inputText24 doesn't get the selected value because the execution of ssjsSelectFunction's code is too late. It gets executed during the refresh of panel "AcordCadru" caused by parameter refreshID. All fields positioned in front of xc:viewpicklist get refreshed before ssjsSelectFunction's code execution. That's why inputText24 doesn't get the new selected value but inputText25 which comes after xc:viewpicklist does.
If you put inputText24 behind xc:viewpicklist then it will get the new selected value.
But, probably you want to have field inputText24 first and the picklist button xc:viewpicklist after. For this
delete the ssjsSelectFunction code
add a computed field in front of inputText24 with pretty the same code
<xp:text
escape="true"
id="computedField1">
<xp:this.value><![CDATA[#{javascript:
var unid = viewScope.unid;
if (unid && unid !== Contr.sv) {
var doc = database.getDocumentByUNID(unid);
var val1 = doc.getItemValueString("txt_numeAcord_1");
Contr.setValue("acord",val1);
Contr.setValue("sv",unid);
}
return "";
}]]></xp:this.value>
</xp:text>
It will set the new selected values to document and made them visible in inputText24 and inputText25 right away.
