How to set empty string value in Rule

Greetings, dear Community!

I have a Combobox with multible values and an Radiobutton with two entries: a value and an empty string (<ENTRY value="">).

Depending on the value of the Combobox, I want to set the value of the Radiobutton. If both entries of the Radiobutton have values, everything works fine. But if I try to set the value to an empty string (<TEXT></TEXT>) in the rule, I get the error "expected token 'Text', got 'Closing tag'.

If I instead use EMPTY and not VALUE in the PROPERTY, the value is set to null and non of the Radiobuttons is selected.

As I am using the value of the Radiobutton in the HTML, the right value would be appreciated.

There is some code, if anyone wants to test around:

The Form parts:

<CMS_INPUT_RADIOBUTTON name="st_text_color" hFill="yes" preset="default" useLanguages="no"> <ENTRIES> <ENTRY value="grey"> <LANGINFOS> <LANGINFO lang="*" label="Grey"/> </LANGINFOS> </ENTRY> <ENTRY value="white"> <LANGINFOS> <LANGINFO lang="*" label="White"/> </LANGINFOS> </ENTRY> </ENTRIES> <LANGINFOS> <LANGINFO lang="*" label="Text Color"/> </LANGINFOS> </CMS_INPUT_RADIOBUTTON> <CMS_INPUT_COMBOBOX name="st_background_color" hFill="yes" singleLine="no" useLanguages="no"> <ENTRIES> <ENTRY value="grey"> <LANGINFOS> <LANGINFO lang="*" label="Grey"/> </LANGINFOS> </ENTRY> <ENTRY value="dark-grey"> <LANGINFOS> <LANGINFO lang="*" label="Dark Grey"/> </LANGINFOS> </ENTRY> <ENTRY value="red"> <LANGINFOS> <LANGINFO lang="*" label="Red"/> </LANGINFOS> </ENTRY> <ENTRY value="dark-red"> <LANGINFOS> <LANGINFO lang="*" label="Dark Red"/> </LANGINFOS> </ENTRY> <ENTRY value="black"> <LANGINFOS> <LANGINFO lang="*" label="Black"/> </LANGINFOS> </ENTRY> <ENTRY value="white"> <LANGINFOS> <LANGINFO lang="*" label="White"/> </LANGINFOS> </ENTRY> <ENTRY value="medium-grey"> <LANGINFOS> <LANGINFO lang="*" label="Medium Grey"/> </LANGINFOS> </ENTRY> <ENTRY value="silver-grey"> <LANGINFOS> <LANGINFO lang="*" label="Silver Grey"/> </LANGINFOS> </ENTRY> <ENTRY value="light-grey"> <LANGINFOS> <LANGINFO lang="*" label="Light Grey"/> </LANGINFOS> </ENTRY> <ENTRY value="dimmed-white"> <LANGINFOS> <LANGINFO lang="*" label="Dimmed White"/> </LANGINFOS> </ENTRY> </ENTRIES> <LANGINFOS> <LANGINFO lang="*" label="Background Color"/> </LANGINFOS> </CMS_INPUT_COMBOBOX>

And my rules:

<RULE> <IF> <OR> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>white</TEXT> </EQUAL> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>silver-grey</TEXT> </EQUAL> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>light-grey</TEXT> </EQUAL> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>dimmed-white</TEXT> </EQUAL> </OR> </IF> <WITH> <TEXT></TEXT> </WITH> <DO> <PROPERTY name="VALUE" source="st_text_color"/> </DO> </RULE> <RULE> <IF> <OR> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>grey</TEXT> </EQUAL> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>dark-grey</TEXT> </EQUAL> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>red</TEXT> </EQUAL> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>dark-red</TEXT> </EQUAL> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>black</TEXT> </EQUAL> <EQUAL> <PROPERTY name="ENTRY" source="st_background_color"/> <TEXT>medium-grey</TEXT> </EQUAL> </OR> </IF> <WITH> <TEXT>white</TEXT> </WITH> <DO> <PROPERTY name="VALUE" source="st_text_color"/> </DO> </RULE>

I think, this problem is due to XML seeing an empty string as the same as null, but maybe someone has come across this and has found another solution!?
