Environment i am working on Tridion 14SP2 and Vanila DB Dump which is bundled with OOTB Installer.

Getting Error after adding the new Checkbox field in the UI Form for PublicationOutput Card. 

Error:

Value is missing for the "Include Publication Output File Mode" field of object "GUID-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx=2=PDF (A4 Manual)=en". [c:11681 ce:GUID-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx ct:CTPUBLICATIONOUTPUT f:1063 fe:FPUBINCLUDEOUTFILEMODE ft:LOV fmin:1 fmax:1] [102006;MissingValueLevelCard]

By following the steps mentioned in the documentation,

I could add the custom field FPUBINCLUDEOUTFILEMODE using the XMLStructre as given below:

<?xml version="1.0" encoding="utf-8"?>
<setup version="2.0">
<fields>
<field element="FPUBINCLUDEOUTFILEMODE" issystem="false" isbasic="true" ismandatory="true" isindexable="false">
<label>Include Publication Output File Mode</label>
<description>Include OutputFileMode in the metadata as a boolean Value If Selected OutputFileMode would be by FileName else would be By GUID</description>
<typelov element="BOOLEAN" ismultivalue="false" />
</field>
</fields>
<cardtypes>
<cardtype element="CTPUBLICATIONOUTPUT">
<fielddefinition>
<cardtypefield element="FPUBINCLUDEOUTFILEMODE">
<lovfield>
<defaultvalue ishvaluetype='element'>FALSE</defaultvalue>
</lovfield>
</cardtypefield>
</fielddefinition>
</cardtype>
</cardtypes>
</setup>

Also configured the MetadataConfog.xml under cleintConfig Folder:

here is the snippet i have added in the metadataconfig file

Here is the customUI Field added into the screen:

i am not sure what i am missing here, 

Also i noticed few other things

If for any outputs if i go and select Properties and view the data i am getting the data this way:

Now if i go and select the check box and click modify this happens

Processing windows runs forever;

I am not sure whether i am missing any steps here.

Any guidance or help would be really helpful.
