[izpack-users] Variables in custom panel are not passed as IzPack variables

[Klaus Bartz]

Hi Yossi,
seems so you have overcomes the bigest obstaclethe starting developing
IzPack panels; the API of panels and to create the WarPathPanel.jar
and put it into $IZ_HOME/bin/panels.
Seems so that the AntInstallerListener will be also start.

I hope your first custom panel will be shown at installation!

I have not tested your panel code, but it seems OK. Only one question
context related...
myAntActionSpec is a little bit wrong (see context related).
UploadFile.xml can be discussed...

I do not know whether you know following or not:
There is one point which will be a little bit "magic" if you do not
know the source code: How can I use own messages.
Simple declare them in the locale files with the right key, no more
references are neede.
For messages we have two xml files for each language; the needed
(and existent) one will be placed in
$IZ_HOME/bin/langpacks/installer/<ISO3>.xml
If you declare e.g.
<str id="WarPathPanel.intro" txt="common user blah blah" />
This messages will be placed on the top of the panel. There are the
messages:
<myPanel>.intro
<myPanel>.info
<myPanel>.required
<myPanel>.notValid
<myPanel>.notwritable
<myPanel>.empty_target
<myPanel>.warn
Not all are used in all sub classes of PathInputPanel.
And for the summary
<str id="WarPathPanel.summaryCaption" txt="Path of JBoss war file"/>

//Has Advantag.war to be exist before installation?? If so, add
	setMustExist(true);
	setExistFiles("Advantag.war");

At this point you have to write that it is a variable.
Do not forget the brackets because we use a special char
(the dot).

      <property name="WAR" value="${Jboss.WarFile}"/>

Uups, a fixed path as dest?? Not really...
