CDE: Change the CCC onclick?

Hi guys,

i´m pretty new to the whole Pentaho Suite.
I am developing a Dashboard with three different Line Charts.

I have three Columns (Headers in HTML with Text in them) which are clickable and change their background-color for example.
It is necessary that a different Line Chart is displayed when I click on the proper Column.
Just like a switch for the different Line Chart Components.

Is this possible without using iFrames?

Best regards,

THaupt.

Fields not available in report when data integration source uses a JSON Input task

May 6, 2016, 6:47 am

PDI 6.1
PRD 6.1

I have a MongoDB that I'm trying to query & transform to create a report for. It seems that any fields I add to the stream through the JSON Input task aren't visible to the report.

Here's a walkthrough of a basic example:
- Have a collection with nested documents
- First MongoDB Input task retrieves OID field and a second field containing the JSON of the nested documents
- Send output to JSON Input task
- Parse JSON in stream to extract additional fields
- Send output to select task
- Remove JSON fields from stream (to clean it up a bit)

Now in PRD
- New report, data integration as data source
- choose transformation created above
- preview query --> receive error
- in console (after changing .bat to use java instead of javaw) - see error about "couldn't find field x in row"
- the fields it always complains about are always the ones that were added to the stream by the JSON Input task

I've been able to avoid this in some cases by not using the JSON Input task and always making sure the MongoDB Input task contains the fields, but this nested document scenario is causing me some grief. I'm currently going to explore using a javascript task to evaluate the json and output the fields I need - and initial tests indicate that fields added to the stream by the javascript task do show up in the report. Wonder if anybody has encountered this - if there's something I'm missing on that particular JSON Input task. It would make my life easier, and the transformation easier to maintain, if I could do all of this in the JSON Input task and not some scripting workaround.

Thanks for sharing any ideas or information you can. This forum has been an amazing resource so far and has helped me work through most issues until now.

Cheers!

Reading multiple Excel sheets to one textfile

I have an Excel workbook with dept figures from each department on different sheets. I want to read all figures from each sheet and write them to rows in a text file with sheetname (dept name) as first column. Is this possible? When I set up an Excel Input and add selected sheets to the import I only get one of them and I also can't figure out how to attach the sheet name as a row in the output textfile. All sheets are the same, they differs from the sheet name.The output text file should be like this:Sheetname1;Sheet1:A1;Sheet1:B1Sheetname1;Sheet1:A2;Sheet1:B2Sheetname2;Sheet1:A1;Sheet1:B1Sheetname2;Sheet1:A2;Sheet1:B2etc.

Component not refreshed in time

May 6, 2016, 9:36 am

Dear Community :

I am using Pentaho CE 6.0 and CDE.

I have a select component with months and a simple variable holding the selected month.
Based on the simple variable month, i refresh a table showing sales data of that month.
The table component has listeners: month and parameters: month, month. The datasource under the table component has also parameters: month, month string.
Whenever my select box changes, my table changes nicely with the selected month data. So far, so good.

However, based on the selected month, I want to hold the quarter in a variable and refresh the sales data of that quarter.
I did this creating a new simple parameter Quarter and a Post-change function in the select component for month, doing:

Code:
function f() {


Dashboards.setParameter('quarter', quarters[Dashboards.getParameterValue('month')-1]);


}
Again I created a table component listening to the month variable (if it listens to the quarter variable it doesn´t do anything) and having as parameters the quarter variable with an underlying Datasource also having parameters quarter.

The problem is that my table component updates 1 click to slow. For example: default select is March (Q4), it shows Q4. clicking on December (Q3) it still shows Q3. Clicking then on November (Q3), it shows Q3.

I find this strange since I also show the content of my quarter variable to the screen, using a text component and a function:

Code:
function() {       
  return Dashboards.getParam("quarter");
}
and here the quarter changes nicely whenever a month is selected.

Can somebody guide me please how to solve this.

Can dashboard designer be used outside of PUC? i'm using Pentaho EE with CDE and other plugins. i was hoping to call it via api like we can do with the analyzer. http://host:port/pentaho/api/repos/xdash/editor does bring up the designer but the file repository folder list is not available so we can't insert files or analyzer reports into it.

Issue with DBF Input

May 6, 2016, 2:49 pm

People, please help.


I'm migrating a database that is in dbf (yes, still people using .dbf's). At some point in processing, the kettle terminates the process and returns me an error that can not convert a string to number. Originally the input field is numeric, the value in error is an exception.

The kettle shows that the value he tried to convert to a number was [$2.55]. Yes, with this dollar sign in front. Analyzing dbf "inside" have not found any trace of something that looks like this, however, when I exported the dbf to text, the record with the error appears. Thus, correcting everything works! I thought the line on dbf with the error, delete it and so the transformation work.

Handmade the solution worked. The problem is that I am reading hundreds of these DBF files. Well, there's the question: is how I make a processing of data passed through the stream before writing them to the destination bank? I tried the solution mentioned by Matt on this post, but unfortunately for me it did not work.

The xDbase step does not allow me to change the field type. I could even force it to be a string, but can not. If I put a select value in order to change the metadata saying that it is a string, not also work. The error occurs before the record out of xDbase step and get to the next step.

So that's my problem.


Does anyone have an idea? Thank you so much guys.

problems with replacing a word.

I have one data file in which regions are named (like for instance Quebec) and I have another file in which Canada is divided into other regions (north, east, central, south and west). I need to combine these two data files and replace the named areas by the geographical position they have in Canada.

What I figured I would do is use the "replace in string" function. So what I do is the following. I specify the fields as follows:
replace.jpg

The output is fine I guess, but instead of replacing the terms in one stream field, it creates a separate stream field for each. I however want it in one field.

replace 2.jpg

As I need to replace a few more terms I will end up with 5 separate stream fields. I think I will have to merge the fields after this step into one? Is my thread of thought right here? Or is there another, better way.

Thanks.

Setting fields (key value pairs) as variable name(s) and value(s) in a ktr

May 8, 2016, 5:35 am

Hi guys,

I have a string that contains a series of key/value pairs that need to be set as variables for the next transformation.

Easy bit is to split the field as rows and then split the resulting field into variable / value (fields)

What I haven't been able to figure out is how to setting these up as variables?

I'd like to be able to reuse this transformation to run other transformations so I can't really "map" the variables in advance.

The downstream transformations may have one variable or 20. This transformation should be able to run both.

I'm not very good with Java so I'd rather not use a java step.

Any help appreciated.

Thanks

Value mapper problem/merging tables problem

May 8, 2016, 11:47 am

I have 2 different CSV files that I have to connect to each other. Both of these files have area descriptions in them but in one they are described by provinces or city names and in the other they are describe by their localization in any of the wind directions (north, east, etc.), this second file also allocates manager names to those wind directions (which manager is responsible for which region). So I thought I should use the value mapper function and assign the region names in such a way that they would be both equal and by this merge the tables. Unfortunately I see that it does not work as I hoped it would. It seems that some of the regions are missing after this step, it is almost as if the mapper is not working properly. I am missing some manager names that I would expect to appear, is there another function to achieve this what I want or am I missing an additional execution that I need to do?

Thanks again for all of your times.

Hello everyone,

I want to use xaction to call a kettle job, and this job contains many transactions. But when I run this xaction on bi server 6.0, some exception occurred..
QQ截图20160509103124.jpg

About my kettle job and transaction:

1. I use kettle variable ${Internal.Entry.Current.Directory}(i also tried to use ${Internal.Job.Filename.Directory}) to specify the path of the transactions in this job.
2. I upload these files into the same directory on bi server
3. It works fine when i use spoon, but seems that ${Internal.Entry.Current.Directory} or ${Internal.Job.Filename.Directory} was not replaced correctly when running on bi server..

Processing GZIP/Deflate xm file from HTTP Post

Hello Community,

I need some help with a process I'm designing that makes an HTTP POST to a web service and receives a gzip file as response. Here you can see the request:

1.jpg

I have been doing some tests using Postman Chrome Extension, which understands and decompress the file:

3.jpg

However, HTTP Post step does not understand the answer (see document field):

2.jpg

In the last step I try to identify the different fields in the xml. I did a test by downloading the XML from Postman and identifying the fields from there and it worked. However, I need to find a way to do it from Kettle without Postman. Do you know a way to decompress the file prior to capture the data stream?

Thanks in advance!
