Potential defect in creating ListGridField

[JLivermore]

SmartClient Version: SNAPSHOT_v9.1d_2013-12-17/PowerEdition Deployment (built 2013-12-17)

IE-8

new ListGridField("class","Class",50);

new ListGridField("class33","Class",50);

new ListGridField("class33","Class33",50);

I get this ERROR for the first 2 code snippets above. I would expect this error on the first one only.

ERROR: 12:57:35.722:TMR0:WARN:Log:'class' is not a valid JavaScript identifier. DataSource and DataBoundComponent field names are required to be valid JavaScript identifiers, the syntax for which is specified by ECMA-262 Section 7.6. Note: The String.isValidID(string) function can be used to test whether a string is a valid identifier. This field applied to [DataSource ID:pivot_table_flat_fact_POF_233]. This will be the last warning.

Can you double-check this result? You show ListGridFields, but the warning is about a DataSourceField, and the identifier being complained about is "class", not "Class".

[JLivermore]

I tried all three examples above and the first two gave me that error.

[Isomorphic]

Just so we're quite clear on the problem, can you show the actual error message resulting from the second sample?

[JLivermore]

ok, when I retested the 2nd example, I got the identical error. I need to check the DataSource fields too, I will post my findings.

[JLivermore]

That was the problem, case 2 now works fine. It was the DataSourceField name in the DataSource named 'class' that was causing that error.

thanks!
