    <p>I've passed the arraylist values from my controller to a gsp page, there I can access the data of the arraylist by using the key names. In that gsp page I've added the following link in my gsp page like</p> <pre><code>&lt;g:link controller="searchFun" action="seeMore" id="" params="[q:params.q,cat:params.cat,stat:'study',ids1:'sm']"&gt;See More&lt;/g:link&gt; </code></pre> <p>When I access the same parameter in other seemore.gsp, I can not access the values by using the key name like this <code>"${fieldValue(bean: result, field: "purpose")"</code>, It throws an exception <code>"No Such property is available for Java.lang.String"</code> But I can use the same code in the <code>index.gsp</code>, there the above code works.</p> <p>My question is how the variable can be passed to another action as it is?</p> <p>Here is my controller and actions</p> <pre><code>*class SearchFunController { def searchableService def index() { def Study def map1=new ArrayList() def tmpStudy=Study1.search(query,[max:500]) Study=tmpStudy.results Study.id.each{ def c=Study1.findAllById(it.value) if(c!=null&amp;&amp;c.size()&gt;0){ c.each{ def sui=it.uniqueIdentifier def sur=StudyUserRole.findAllByStudyUIAndUserName(sui,session.user) if(sur!=null&amp;&amp;sur.size()&gt;0){ sur.each { def stu=Study1.findAllByUniqueIdentifier(it.studyUI) def loSui=it.id stu.each{ if(map1==null&amp;&amp;map1.size()==0) map1.add(it) else if(!map1.containsAll(it)){ println "Added here 2" map1.add(it) println map1 return [study:map1.unique()] }}}}}}}} def seeMore() { return [s:params.s] }* </code></pre> <p>index.gsp</p> <pre><code>*&lt;tbody&gt; &lt;g:each var="result" in="${s}" status="index"&gt; &lt;g:if test="${index&lt;5}"&gt; &lt;tr style="max-height:10px;overflow:hidden;"&gt; &lt;td&gt; ${index+1} &lt;/td&gt; &lt;g:if test="${fieldValue(bean: result, field: "uniqueIdentifier")!=null}"&gt; &lt;td&gt;&lt;g:link controller="searchFun" action="view" id="${fieldValue(bean: result, field: "uniqueIdentifier").replaceAll("\\[", "").replaceAll("\\]", "")}" params="[q:params.q,cat:params.cat]"&gt;${fieldValue(bean: result, field: "uniqueIdentifier").replaceAll("\\[", "").replaceAll("\\]", "")}&lt;/g:link&gt;&lt;/td&gt; &lt;/g:if&gt; &lt;g:else&gt; &lt;td&gt;--&lt;/td&gt; &lt;/g:else&gt; &lt;g:if test="${fieldValue(bean: result, field: "name")!=null}"&gt; &lt;td style="width:40%; height:2px; overflow:hidden;"&gt;${fieldValue(bean: result, field: "name").replaceAll("\\[", "").replaceAll("\\]", "")}&lt;/td&gt; &lt;/g:if&gt; &lt;g:else&gt; &lt;td&gt;--&lt;/td&gt; &lt;/g:else&gt; &lt;g:if test="${fieldValue(bean: result, field: "protocolType").equalsIgnoreCase("[null]")}"&gt; &lt;td&gt;--&lt;/td&gt; &lt;/g:if&gt; &lt;g:else&gt; &lt;td&gt;&lt;g:set var="dc" value="${fieldValue(bean: result, field: "protocolType").replaceAll("\\[", "").replaceAll("\\]", "").split(" ")}"&gt;&lt;/g:set&gt; ${dc[0].capitalize()} &lt;/td&gt; &lt;/g:else&gt; &lt;g:if test="${fieldValue(bean: result, field: "purpose").equalsIgnoreCase("[null]")}"&gt; &lt;td&gt;--&lt;/td&gt; &lt;/g:if&gt; &lt;g:else&gt; &lt;td&gt;&lt;g:set var="dc1" value="${fieldValue(bean: result, field: "purpose").replaceAll("\\[", "").replaceAll("\\]", "").split(" ")}"&gt;&lt;/g:set&gt; ${dc1[0].capitalize()} &lt;/td&gt; &lt;/g:else&gt; &lt;g:if test="${fieldValue(bean: result, field: "statusId").equalsIgnoreCase("[null]")}"&gt; &lt;td&gt;--&lt;/td&gt; &lt;/g:if&gt; &lt;g:elseif test="${fieldValue(bean: result, field: "statusId").equalsIgnoreCase("[1]")|| fieldValue(bean: result, field: "statusId").equalsIgnoreCase("1")}"&gt; &lt;td&gt;&lt;span class="label label-success"&gt;Available&lt;/span&gt;&lt;/td&gt; &lt;/g:elseif&gt; &lt;g:else&gt; &lt;td&gt;${fieldValue(bean: result, field: "statusId").replaceAll("\\[", "").replaceAll("\\]", "")}&lt;/td&gt; &lt;/g:else&gt; &lt;/tr&gt; &lt;/g:if&gt; &lt;/g:each&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;/div&gt; &lt;div class="span12"&gt; &lt;g:link controller="searchFun" action="seeMore" id="" params="[s:s]"&gt;See More&lt;/g:link&gt; &lt;/div&gt;* </code></pre> <p>In index .gsp its worked and i can see the data, but when i clicke the seemore link in the seeMore.gsp it throws an error. The same gsp code I used in seeMore.gsp too.</p>

    2. COThe controller action that is upstream from seemore.gsp needs to return your result bean in the model. You can get a better [understanding of controllers](http://grails.org/doc/latest/guide/theWebLayer.html#understandingControllersAndActions) and actions on the official reference.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
