Re: Invalid conversion error when using TEXT datatype in INPUT

Hello Mike,

in TUI mode there is one more little bug (I think):
When you start an external text editor with ! in a blob field, change 
the content, save & exit, the the content of the form field is not 
updated. I'm not sure what the original Informix behaviour is, but AFAIK 
the field content is updated after the end of the external-editor.

the datatype-conversion bug still exists in the XML UI. Can you give me 
a hint where this conversion take place? I'm a bit lost in the aubit 
sources :-)
