Title: Message

I would make a Set available from your Action and have your Action do the work of creating the Set from your List

Hmm, well our result is in a list containing beans with result data.

 

Can i set a value in the stack, like prevValue. And later in the iterator loop check if this prevValue is equal to newValue.

 

Like this? OrganizationName is the beans property value. SearchResult gives a list containing beans (POJO's).

 

<ww:iterator status="row"  value="searchResultTransport.searchResult"  >
<ww:if test="organizationName != prevOrgName">

  ....write orgName

</ww:if>

<ww:set name="prevOrgName" value="organizationName" />

</ww:iterator>

 

or is there a better way to deal with this.

For 1: No... use a Set instead of a List if you want only unique values

About the iterator tag.
1. Does there exist a function with the iterator tag, that check if the prev, value is the same as the next. Then if so skip printing that value.

2. Is there a odd/even  handling when iterating through a list? So you can print out a table with every odd row with a grey background, and even row as white.

Is there some good docs about the UI iterator tag? Any help is appreciated.
