Talend community forum / Use Context with Directory Field in UI

Tags: [context, Context on Directory Field, java]

Hi,
I am creating a Directory type parameter in a custom component.But when i try to use context in that field it fails it simply takes the value that in there in the directory box ex "context.GIP_DATAFILE_LOCATION" instead of the value of the context. Is this a bug because context is working fine with text fields in the same component.

I am using talend version V4.0.3

My entry in component xml file tGipOutput_java.xml

<PARAMETER NAME="DATAFILELOCATION" FIELD="DIRECTORY" NUM_ROW="23" REQUIRED="true" REPOSITORY_VALUE="DATAFILELOCATION">
<DEFAULT>"__COMP_DEFAULT_FILE_DIR__" OR context.GIP_DATAFILE_LOCATION</DEFAULT>
</PARAMETER>

In the code

<%
CodeGeneratorArgument codeGenArgument = (CodeGeneratorArgument) argument;
INode node = (INode)codeGenArgument.getArgument();
String cid = node.getUniqueName();
String file_path = ElementParameterParser.getValue(node,"__DATAFILELOCATION__");

%>
int nb_line_<%=cid%> = 0;
String file_path__<%=cid %> ="<%=ElementParameterParser.getValue(node,"__DATAFILELOCATION__").replaceAll("\"", "")%>";

Regards
Siddhartha

Hi

<DEFAULT>"__COMP_DEFAULT_FILE_DIR__" OR context.GIP_DATAFILE_LOCATION</DEFAULT>

It is impossible to set the context variable in the xml file, the default value should be
<DEFAULT>"__COMP_DEFAULT_FILE_DIR__"</DEFAULT>
Please refer to the directory filed on tFileList component.

Best regards

Hi Shong,

You are saying that "it is is impossible to set the context variable in the xml file". But within the same component, we have text-fields, where we use context-variables to set the values. E.g. to set an IP-Address, the relevant section in the xml-file looks like:
<PARAMETER NAME="IP" FIELD="TEXT" REQUIRED="true" NUM_ROW="88" REPOSITORY_VALUE="IP">
<DEFAULT>"Enter IP Address" OR context.GIP_IP_ADDRESS</DEFAULT>
</PARAMETER>

The above section works perfectly. So should the same approach not work for directory-fields if it does for text-fields?

Kind regards,
Rico

Hi Rico
Sorry, I made a mistake, thanks for correcting me. I test to modify the xml file of tFileList component like this and it works.

<PARAMETERS>
<PARAMETER NAME="DIRECTORY" FIELD="DIRECTORY" NUM_ROW="1">
<DEFAULT>context.filepath</DEFAULT>
</PARAMETER>

But when i try to use context in that field it fails it simply takes the value that in there in the directory box ex "context.GIP_DATAFILE_LOCATION" instead of the value of the context.

Are you sure you have removed the double quote in the javelet files? even thought I see you add this line of code
String file_path__<%=cid %> ="<%=ElementParameterParser.getValue(node,"__DATAFILELOCATION__").replaceAll("\"", "")%>";

Best regards
Shong
