Loop

[ideasandinno...@gmail.com]

Hi

I have used a loop to write multiple entries into spreadsheet. I have used default("") function in case if any of the values in the column is not entered. But actually this function is not working. Is there any alternative method for my requirement?
The error thrown out is
2014-07-14T08:17:11+0000 - Task "update the array" (id: 122[0] - status: ABORTED): Error while processing {Orderarray.slNo}
Expression Orderarray is undefined on line 1, column 3 in update the array.
Please assist.

Thanks

Hi,

Can you send me the code where you set your default value?

-> If you want to set the default value of array in Freemarker, the expression is : your_array_variable?default([])

-> If you want to set the default value of string in freemarker, the expression is:  your_string_variable?default("")

Regards,

Richard

Hi

The code which I am using is given:

<gsx:slno>${Orderarray.slNo[P_index]?default("")}</gsx:slno>
<gsx:devicetype>${Orderarray.device_type[P_index]?default("")}</gsx:devicetype>
<gsx:quantity>${Orderarray.quantity[P_index]?default("")}</gsx:quantity>
<gsx:unitprice>${Orderarray.unitprice[P_index]?default("")}</gsx:unitprice>
<gsx:taxrate>${Orderarray.taxrate[P_index]?default("")}</gsx:taxrate>
<gsx:totalbilling>${Orderarray.total[P_index]?default("")}</gsx:totalbilling>
<gsx:instcharges>${Orderarray.instlln_charges_device[P_index]?default("")}</gsx:instcharges>
<gsx:servicetaxrate>${Orderarray.service_tax_rate[P_index]?default("")}</gsx:servicetaxrate>
<gsx:totamt>${Orderarray.amount[P_index]?default("")}</gsx:totamt>
<gsx:subscriptionrate>${Orderarray.subscription_rate[P_index]?default("")}</gsx:subscriptionrate>
<gsx:subscriptiontax>${Orderarray.tax[P_index]?default("")}</gsx:subscriptiontax>

These values are used inside a loop with loop condition as ${Orderarray.slNo}
where Orderarray is the variable name of the array widget ans slNo is the variable name of the first column in the widget.

Thanks

Hi,

The error message is showing that

Orderarray 

doesn't exist.

I think you should check that first.

And, another tip about ?default("") syntax:

If you know that Orderarray (parent node) exist, but child node might not exist, below is fine

Orderarray.slNO[1]?default("")

But if parent node is missing in above situation, it will show error, because it expected that to exist _before_ checking if child node existed.

What you can do is, something like this

(Orderarray.slNO[1])?default("")

This will substitute with "", for both parent/child missing cases.

Best regards,

Taka
