How can a hyperlink in a table load an image in a new page?
Hello,
I磎 using Java Studion Creator 2 Update 1 an I have following problem:
In my jsp-page (main.jsp) I have a table component with an image hyperlink (showOriginal) in the first column and a hyperlink to another page in the second. On this page is also a hyperlink, which refreshes the table.
The hyperlink "showOriginal"should open an new browser window and display an image depending on the selected table row. I set the property "target" for the hyperlink to "new Window" and specified an event_method (showOriginal_action() ), which gets the image for the selected table row and returns a new jsp-page (originalView.jsp).
OriginalView.jsp has only one image component. The url for this image is set by the event_method of the image-hyperlink of main.jsp. Everything works fine but if I press the refresh link on the main.jsp to refresh the table (after opening the new window with the image), the image is also loaded in the main.jsp and every other link causes the same problem. Even when I close the window with the image, the same happens. It seems to my like I`m still on the main.jsp and not on the originalView.jsp (after I included a </redirect> tag in navigation.xml, I can see in the browser address line that the OriginalView.jsp is loaded) and the main.jsp "thinks" that the current content of itself is the image?
I changed the return value of showOriginal_action() to null (because of the target property I always get the originalView-page) and then I included an onClick-method for the imagehyperlink to open a new window with the image via javascript but this didn`t work because the onclick is performed first and at this time I don`t have the image url yet (because first I must know, which row was selected in the table).
Am I doing something wrong or is this not the correct way to do this? I just want to click the link in the table and a new window/page should be opened, which displays the image, independent from anything else. and all the links in the main-page must still work properly.
I appreciate any help & suggestions.
thanks
