I am attempting to write the following bean :

-----------
package com.adaptavist.confluence.builder.layouts.model;

public class SpaceDefault {
private String layoutId;
private boolean locked;

public SpaceDefault() {
}

public SpaceDefault(String layoutId, boolean locked)

{ this.layoutId = layoutId; this.locked = locked; }

public String getLayoutId()

{ return layoutId; }

public void setLayoutId(String layoutId)

{ this.layoutId = layoutId; }

public boolean isLocked()

{ return locked; }

public void setLocked(boolean locked)

{ this.locked = locked; }

}
-----------

Where layoutId == 'test1' and locked == 'true' (or false, happens either way), I am using the following code to call for the write:

----------
private static final String SPACE_DEFAULTS = "com.adaptavist.confluence.builder.themes.spaceDefaults";
private TreeMap spaceDefaults;

private void writeSpaceDefaults()

{ bandanaManager.setValue( new ConfluenceBandanaContext(), SPACE_DEFAULTS, xStream.toXML(spaceDefaults) ); }

public void setSpaceLayoutLock (String spacekey, boolean locked) throws BuilderException {
initData();
if (spacekey==null)

{ spacekey = GLOBAL_SPACE; }

SpaceDefault spaceDefault = (SpaceDefault) spaceDefaults.get(spacekey);
if (spaceDefault==null)

{ spaceDefault = new SpaceDefault(DEFAULT_LAYOUT_ID,locked); }

else

{ spaceDefault.setLocked(locked); }

spaceDefaults.put(spacekey,spaceDefault);
writeSpaceDefaults();
}
----------

To be honest .. this also happens with every other write I have ever attempted to make to bandana in 2.3 when called through DWR, however with the other writes the data was actually getting written away so I have left it as something that could be resolved later (when 2.3 is a bit more stable) ... however for this write the data is NOT getting written away, hence this is causing me major problems in my development work.
