Dear mailinglist members, this might be a trivial problem, but even after a longer research I haven't found a solution to it. I try to insert a non-breaking space via a button created by a framework. I use the following code within an <action>: <actionMode> <field name="xpathCondition"> <String></String> </field> <field name="argValues"> <serializableOrderedMap> <entry> <String>text</String> *<String>{CODE_FOR_THE_NON-BREAKING_SPACE}</String>* </entry> </serializableOrderedMap> </field> <field name="operationID"> <String>ro.sync.ecss.extensions.commons.operations.InsertOrReplaceTextOperation</String> </field> </actionMode> I added a placeholder CODE_FOR_THE_NON-BREAKING_SPACE above to show you were I want to fill in my non-breaking space. I tried which caused my whole framework to NOT be read by Oxygen XML Author. I tried which just created a regular space. I tried   which just created exactly these characters as a string in my XML document. I tried several other things which all didn't work. What do I have to put between my opening and closing <String> tags? Thanks in advance and kind regards Christian Achter
