Clarity

Hello Everyone,
Here I am Using clear function for a Variable but its not working.

<gel:script

xmlns:core="jelly:core"

xmlns:file="jelly:com.niku.union.gel.FileTagLibrary"

xmlns:gel="jelly:com.niku.union.gel.GELTagLibrary">

    <core:forEach begin="1" end="2"  var="test">   

<file:readFile fileName="D:\Gel Script Docs\JS Custom Scripts\test.csv" embedded="false"

var="input"/>

<gel:out>  ${test} Input has ${input.size()} rows.</gel:out>

    <core:forEach begin="1" end="4" indexVar="i1" items="${input.rows}" var="row">   

    <gel:out>IndexVar ---------------${i1}</gel:out>

    <gel:out>q Username = ${row[0]}</gel:out>

<gel:out>First = ${row[1]}</gel:out>

<gel:out>Last = ${row[2]}</gel:out>

    </core:forEach>

    <gel:out>132 ${input.clear()} </gel:out>

    </core:forEach>

</gel:script>

When i run this script
For the First time forEach Iteration it shows 1 Input has 4 rows

for the Second time forEach Iteration it shows 2 inout has 8 rows
It means Clear is not working

could you help me out How to use Clear.

Thanks.

You may try this  http://commons.apache.org/proper/commons-jelly/tags.html#core:remove

A defect had been created for this previously (#clrt-70265 "GEL file library tag readFile retains and accumulates old data when reading from multiple files") but it was not something that any customers had encountered or reported.

Could you please raise a support ticket for this, indicate your product version that this is affecting you on, and give the above reference?

The following was given to describe a workaround of sorts at the time (it is not trivial or straight forward):

Revise the algorithm into 2 loops, one to iterate over the files and accumulate the data into the rows array (storing separately the quantity of rows in each if needed), and the other to then iterate once over the final set of file rows all together.

 

 

Note that this workaround would need to be removed again if the defect is fixed as the lack of data accumulation would then mean it is no longer aggregated, by reverting the algorithm to an outer loop of files being read and an inner loop iterating over the rows for just that file.

I don't know if that helps in the meantime, but the storage mechanism used in the tag for the data isn't exposing methods for clearing/resetting, so it appears to need to be another way required like this workaround.
