checkbox problem in EP5SP5 (unable to find method: key)

Hello,

I experience a checkbox problem on EP5SP5. Here is the error:

Caused by: com.sapportals.portal.prt.servlets_jsp.server.jsp.ParseException: Unable to Find Method : key at com.sapportals.portal.prt.servlets_jsp.server.jsp.TagBeginGenerator.generateSetters(TagBeginGenerator.java:224)

at com.sapportals.portal.prt.servlets_jsp.server.jsp.TagBeginGenerator.generateServiceMethodStatements(TagBeginGenerator.java:267)

If I delete the "key" in the checkbox tag I get an error with "Unable to Find Method : text"!

It works fine in the pdk environment. Any ideas?

Cheers, Jens
