Parsing the data in js function
and concatenating data from child nodes with comma as delimiter
Dr. Watson,40
and assigning this value to select option using
new Option("text", concatenatedString)
After submitting the page selected option (multiple select allowed) value is again splitted in java with comma.
Issue arises when there is comma in data obtained from ajax call in any of the nodes
Dr, Strange,55
Increasing number of comma and leading to number format exception: type mismatch due to index.
To keep changes to minimum, Is it safe to replace comma in ajax data
with , and replace again in java with comma to avoid the
issue or any other way to handle?
Or Can we bind an array with
select option value tag using new Option("text", array) and get
value of array in java using its index?

I'm having a csv file with two columns for example column A and Columb B. Column B consists of string value like this : I am, doing good. so when I try to insert this data into a database only the string I am is getting inserted. I just want to know what attribute I need to add to the process group so that I am, doing good will get inserted to the database
The attached image consists of the attributes in the current process group
I have a nifi flow that takes in .csv files and partitions each into multiple records with each csv column value added as an attribute.
At one point in the flow, I'd like to collect the value of one attribute from each record that passes though. There could be from 0 to n collected. Once I have the list, it'll be emailed out.
I'm trying to avoid me (or someone else) getting bombed with emails if there are 200+ bad records in a file. So if I could collect for a fixed period of time or until another attribute (filename) changes, that would be great.
I've tried merge content and record. I even tried replace text to replace the content w/ just the attribute value I want to save and merging those, and a slew of other things.
Is there a simple way to do this in nifi?
Have you tried UpdateAttribute with a new attribute of type array. When each flowfile passes the this processor you could continue to update the value of this attribute by appending a new value to the array, attribute.
However, as #daggett pointed out, it will be helpful if you can provide the input and expected output.
I am building a generic CSV output module with a variable number of columns. The DataFormat in BW (5.14) lets you define repeating item and thus offers a list of items that I could use to map data to in the RenderCSV step.
But when I run this with data for >> 1 column (and loopings) only one column is generated.
Is the feature broken or do I use it wrongly?
Alternatively I defined "enough" optional columns in the data format and map each field separately - no really generic solution.
Looks like In BW 5, when using Data Format and Parse Data to parse text, repeating elements isn’t supported.
Please see https://support.tibco.com/s/article/Tibco-KnowledgeArticle-Article-27133
The workaround is to use Data Format resource, Parse Data and Mapper
activities together. First use Data Format and Parse Data to parse the
text into the xml where every element represents one line of the text.
Then use Mapper activity and tib:tokenize-allow-empty XSLT function to
tokenize every line and get sub-elements for each field in the lines.

As a beginner to TOS for BD, I am trying to read two csv files in Talend OS, i have inferred the metadata schema from the same CSV file, and setup the first row to be header, and delimiter as comma (,)
In my code:
The tMap will read the csv file, and do a lookup on another csv file, and generate two output files passed and reject records.
But while running the job i am getting below error.
Couldn't parse value for column 'Product_ID' in 'row1', value is '4569,Laptop,10'. Details: java.lang.NumberFormatException: For input string: "4569,Laptop,10"
I believe it is considering entire row as one string to be the value for "Product_ID" column
I don't know why that is happening when i have set the delimiter and row separator correctly.
Schema
I can see no rows are going from the first tInputFileDelimited due to above error.
Job Run
Input component
Any idea what else can i check?
Thanks in advance.
In your last screenshot, you can see that the Field separator of your tFileInputDelimited_1 is ; and not ,.
I believe that you haven't set up your component to use the metadata you created for your csv file.
So you need to configure the component to use the metadata you've created by selecting Repository under Property Type, and selecting the delimited file metadata.
I'm using a grid which have editurl: "clientArray",datatype: 'xmlstring', datastr: '<%=_xml_string %>'.
I have a button in my page , and when i click it i make an ajax call and get an xml containing new rows that i want to add to my grid.
Currently i'm looping through the xml rows and using addRowData for each row.
My question is how can append these rows to the current grid? I want the rows that are currently in the grid to still be there and append to them the new rows from the xml i get.
Thank's In Advance.
You can for example prepare an array of data with the new rows. You can add all the rows in one call of addRowData (read the documentation for more information about different parameters of addRowData).
The things will be more easy if you would return JSON data from the server instead of XML. It is recommended for the most situations. Then you can just make one call of addRowData with the data returned from the server to append there to the grid. Optionally you can needed to use small customization of the localReader (see here for more information)
depending on the formatting of the returned data, you could use addXMLData, however you may have to manipulate the returned XML first in order to have it format correctly.
