PK58103: Nested custom tags that declare variables cause bogus .jsp valid ation errors

Rational Software Architect, Version 7.0.0.7
Rational Application Developer for WebSphere Software, Version 7.0.0.7

APAR status

• Closed as program error.

Error description

• In a .jsp file, nested custom tags of the same name that define
  variables are not properly interpreted causing bogus validation
  errors to be reported in the .jsp. e.g.:
  
  
  
  ?@ taglib uri='/WEB-INF/mytags.tld' prefix='my'?
  
  
  
  ?my:customTag declareVariable='foo'?
  
    ?my:customTag declareVariable='bar'?
  
     ....
  
    ?/my:customTag?
  
  ?/my:customTag
  
  
  
  If the 'customTag' tag impl. declares any variables via extendin
  g the
  TagExtraInfo class, the .jsp validator will report bogus errors
  such as:
  
   Syntax error, insert '}' to complete ClassBody.
  
  
  This can be worked around by declaring the taglib a second time
  with a
  different prefix for use in the nested tag:
  
  
  
  ?@ taglib uri='/WEB-INF/mytags.tld' prefix='my'?
  
  ?@ taglib uri='/WEB-INF/mytags.tld' prefix='my2'?
  
  
  
  ?my:customTag declareVariable='foo'?
  
    ?my2:customTag declareVariable='bar'?
  
     ....
  
    ?/my2:customTag?
  
  ?/my:customTag?
  

Local fix

Problem summary

• Improper handling of nested custom tags with the same name
  were causing syntax problems during validation.
  

Problem conclusion

• Handling of nested custom tags has been reworked to include
  tags with the same name.
