How to use charAt() in a highlight expression? [message #891888] Tue, 26 June 2012 08:42 Go to next message
Eclipse UserFriend
I have been trying to use the following expression in a highlight rule.

row["Status"].charAt(0) equalTo '1'


It never seems to work.

I also tried

new String(row["Status"]).charAt(0) equalTo '1'

row["Status"].charAt(0) == '1' IsTrue


... no luck

Am I doing something wrong here?


On a related point:
I believe that the data is correct but I would like to debug this or spit out some kind of trace to make sure. How could I do this?

Is row["Status"] a string? Take a look at the attached example. Select
the product code and see the highlight rule.

Also may want to put a check in for null, because this will most likely
cause the highlight to fail.

Have you tried like this?

(row["Status"] != null) && (row["Status"].charAt(0) == '1')

Thanks for the replies.

I am pretty certain that the value is a string and is not null. The string is always 2 chars, xy, where x indicates attendance (0 or 1) and y is the role (., M, B or X). The role is output as text in the cell. The attendance is used highlight the cell (change background colour).

The role value does appear correctly using normal data binding (e.g. dataSetRow["Day1"].charAt(1))

Is it possible to debug javascript?

I am not certain why this happening. Can you reproduce with the sample db?
