Error:

Custom tag attribute list cannot be runtime expression. value: "[${prty.propertyConcern}]"

Please help me. how to resolve this.

Answer 1

Such expressions were allowed in earlier releases of Struts2, but were turned off after struts 2.0.10 to resolve a security issue.

You should be able to access the "prty" object in struts tags using this alternative syntax:

<s:select list="#attr.prty.propertyConcern" listKey="prtyCrnId" listValue="concern.concernText"></s:select>

Answer 2

Modifying fieldValue="#attr.resultTable1.id" to fieldValue="%{#attr.resultTable1.id}" resolved my problem.

i.e.:

<display:table name="libraryList" requestURI="showCopyTravelType.action" sort="external"
defaultsort="1" pagesize="10" uid="resultTable1" partialList="true" size="totalRecordCount">
<display:column title="Select">
<s:checkbox id="copiedFlag" name="copiedFlag" fieldValue="%{#attr.resultTable1.id}" />
</display:column>
<display:column property="code"/>
<display:column property="name"  />
<display:column property="description"  />
<display:footer>
<s:submit action="copyTravelType" />
<s:submit action="searchTravelType"/>
</display:footer>
</display:table>

Answer 3

<s:select list="#attr.prty.propertyConcern" listKey="prtyCrnId" listValue="concern.concernText"></s:select>

If we want a list then the parameter should passed like:

list="%{#attr.prty.propertyConcern}"
