196 Chapter 11 Preventing and Handling Errors

Problem: Invalid attribute or value.

If you use an invalid attribute or attribute values, ColdFusion returns an error

message. To prevent such syntax errors, use the ColdFusion syntax validation tools

in ColdFusion Studio.

Problem: Mismatched quotes and escape characters.

Check strings in attributes and expressions for proper placement of single and

double quotes. Color coding in ColdFusion Studio can help you spot improper quote

placement.

Problem: You suspect that there are problems with the structure or contents of a

complex data variable, such as a structure, array, query object, or WDDX-encoded

variable.

Use the

cfdump tag to generate a table-formatted display of the variable’s structure

and contents. For example, to dump a structure named

relatives, use the following

line. Note that you must surround the variable name with pound signs.
