Problem understanding Permission Set xml in Eclipse IDE

Question

I have a Permission Set which has access to some Classes and Pages and one Custom Field on the Account object.

When I am trying to see the file in Eclipse IDE, it shows as just the following, even after trying to re-synchronize and update the file from server. Is it a bug with Eclipse Force.com IDE?

<?xml version="1.0" encoding="UTF-8"?>
<PermissionSet xmlns="http://soap.sforce.com/2006/04/metadata">
    <hasActivationRequired>false</hasActivationRequired>
    <label>BPGovernance Permission Set</label>
</PermissionSet>

Where are my class and field permissions?

Edit:

Created a fresh project and took just the Permission Set only. Still same result.

Edit:

Added the classes and pages and the custom field components to the project. Now I see correct xml, which is very strange because in my original project (which gave the empty xml), all these classes and fields were present too. Now it looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<PermissionSet xmlns="http://soap.sforce.com/2006/04/metadata">
<classAccesses>
    <apexClass>BPGConfigController</apexClass>
    <enabled>true</enabled>
</classAccesses>
<classAccesses>
    <apexClass>MetadataController</apexClass>
    <enabled>true</enabled>
</classAccesses>
<fieldPermissions>
    <editable>false</editable>
    <field>Account.FormulaHyperlinkFieldNew__c</field>
    <readable>true</readable>
</fieldPermissions>
<hasActivationRequired>false</hasActivationRequired>
<label>BPGovernance Permission Set</label>
<pageAccesses>
    <apexPage>BusinessPartnerDetails</apexPage>
    <enabled>true</enabled>
</pageAccesses>
</PermissionSet>

In Force.com IDE (Eclipse), you need to refresh whole permission set folder (not the permission set file itself) in order to get complete XML and dependencies. Profiles also have similar behavior.
